You don't need a hammer drill to drill into concrete, brick, or stone. Concrete is the hardest of the materials, and a regular drill will work just fine; it's just a bit slower, and you will have to apply more force.
Any time you plan to use concrete anchors or concrete screws, you will first need to drill the appropriately sized hole into the concrete So first, you need the correct size masonry drill bit, then a decent quality power drill.
From there, simply mark the location, carefully get the hole started, then drill just like you'd drill into any other surface.
Once you have the hole drilled about 1/4" deeper than the anchor or screw you'll be using, clean out the hole thoroughly and then pound in the anchor or screw in the tapcon screw.

Having drilled thousands of holes in masonry I can say that having the right tool for the job makes things go much smoother and quicker, and that would be with a rotary hammer drill. Yes you can use a regular drill with a masonry bit, and as commented on, you're going to have to use some physical pressure to get the job done. I believe the point is, if you only need a few holes for a specific install then it isn't necessary to blow a bunch of money for another tool. However, if you're doing this in a repetitive fashion then save your body and energy and use the correct tool for the job and get the job done more efficiently.
Agreed
Also depends on the material you are drilling. I know this video is about concrete, but a regular drill even with a masonry bit would just simply not work on certain brick and concrete that is extra hard, old brick especially. There are some materials that requires that hammering effect which chips away at the material as opposed to just drilling it.
Can you please share what's a good hammer drill to buy and drill bit ( including manufacturer) will be greatly appreciated?
@@anilg28 sorry, I missed your inquiry, I would recommend an SDS hammer drill. I have a Dewalt myself but there's lots of them out there, corded and battery models. Folks tend to be brand loyal so take a look at your favorite first. On some of the SDS drills you can get attachments that will do things like drive a ground rod in the ground,.. very helpful for electricians.
Not to mention the added stress put on the regular drill motor, battery and gears. For a hole or two probably okay but anything more would be not good.
Drill with a smaller hole because it’ll be easier going through the concrete, then move up to the larger drill bit. It takes less toll on your drill,especially if it’s cordless.
Thanks for the tip.
Do you also recommend using water as a lubricant?
@@zanderesp4295probably just for indoors
Pilot holes? No shit
Really stupid question but for clarification, you mean you would recommend drilling a smaller bit first and then use the size for your anchor? I ask only because I have yet to see it mentioned for masonry drilling but of course it's mentioned for wood drilling...since brick can be more brittle some times, as a newb DIYer I don't know when it comes to brick
Good luck with this approach. I tried this when I moved from my old home into my current one. In the old house I could easily drill into the wall with a normal (corded) drill and a masonry bit. Tried that in the new one, took me an hour, I got about 5 mm in and I had to get a new masonry bit. I also bought a hammerdrill and it took me 5 seconds.
This same wall, I hired someone to drill a hole for the kitchen ventilation. He came, and then used a huge diamondcore drill with watercooling that he bolted on the wall with 4 separate bolts. Still took him 5 minutes to get through the first wall at full power. Yeah, my walls are a bit of an outlier, but still. If you find yourself with really hard concrete, get a hammer drill. It's way easier.
Yes, and also hire someone making a living out of this as you correctly did.
One of the best presentations of any DIYer that I've seen.
It’s a good idea to mark the hole's centre position with a cross that’s a bit larger than the drill bit. That way, if the drill drifts at the start you won’t loose the correct centre position if the drill moves a little and scrubs some of the mark out.
Good tip. Thanks
This was one of the most helpful videos. I used the same drill your using to install a sturdy ground anchor, the cement was almost as easy as wood. At first I tried a cheap bit - it overheated and barely made the hole. Then I switched to a quality bit - HUGE difference. I'm also 240 which probably helped - thank you for saving me from buying an overpowered tool that I'd never use.
You’re welcome!
You could have rented the drill with a bit for like $35 or less probably.
I already had the drill ...@@berzerkbankie1342
I've used masonry drills on many occasions and have to use one again today. SO, being a terrible procrastinator, I thought I'd have a look at CZcams for how to use a masonry drill, before starting the job. It turned out well because I watched this video. I'd not initiated the hole on non-hammer before, so I'll give that a go. And I'd never considered not using a hammer drill for masonry bits, so that's a lesson too. Anyway, very good video, it's now 10 minutes later, 12 mid-day where I am, meaning it's lunch time. I'll now start my job after lunch. Thanks very much for providing an excellent distraction!!! I've got to go now because my wife is screaming at me to get off the computer...
Haha, enjoy the new tips.
I did this experiment on my own as I did not want to go out an buy a hammer drill if I didn't need it. After going through 2 batteries and not even getting through 1 1/2 holes I decided to buy a drill with the hammer feature. It was a night and day difference. It took me just 5 minutes to drill the rest of the holes I needed.
Glad you got it figured out! Thanks for commenting.
Very beginner question….What setting was used for the cordless power drill? (1v2 and 1-12)
Dan, thanks for your instructional video. Really appreciate it. Can you also share what anchor (including picture) would use for a 6" thick cement deck for a storage shed in the back yard. Any feed back appreciated.
Thanks for that side by side comparison. Good to know!
Glad it was helpful!
Option 3: Rotary Hammer plus SDS bits. The SDS bits are splined which allows for a superior hammering action. Can also be used as a mini breaker (with appropriate chisel bits). Well worth the investment.
Yeah, now its not expensive to buy off brand one. China makes millions of them, and its completely ok if you don't use it as professional tool every day.
Thanks for this video, I was looking for something like this a while back and this would have helped. It helps now!
Glad to hear it!
Quality bits are a must! Thanks
Yes, they definitely help!
The difference is wear and tear on your cordless. If you’re doing lots of holes you will burn up the cordless, a good sds hammer drill will last years with daily use. For a home owner this is fine, but for me, a 25 year veteran in structural concrete form work, it’s not even comparable.
Makes sense.
Yes...I'm sure, he talking about in a pinch dude...he said if you don't have a hammer drill or can't afford it...geez
No kidding! I burn up at least 10 cordless drills a year from drilling concrete with them. Happens all the time. All my coworkers have the same complaint. A cordless drill will only last for about 1,000 holes before it burns up.
@@StayHandy Stop being a stupid p.ick. You NEED a rotary hammer not a regular hammer dill to drill concrete and even brick.
Damn right buddy
You can keep a cup or bottle of water to pour water around and into the hole to keep the bit cool which helps with wear.
Great tip!
Thank you! this helps a bunch.
What drill bit material used - cobalt? - for drilling through brick and concrete. How do I make I nice circular indention that will fit the square part of these bolts just under the head of the bolts? My biggest drill bit won’t so it. Is there a special type of drill bit for this application?
It depends on the concrete. If it's fresh concrete with lots of sand and no gravel, then it can be relatively easy to drill through. If it's decades-old concrete with lots of gravel then you'll want a hammer drill.
That's the best reason for a hammer drill, getting through rocks in the concrete without problems like the hole getting huge or having to stop to break each rock by hand.
Hi, I believe that the proper drill for this job would be a SDS hammer. It is significantly faster then a hammer drill and it will take about 3-4 seconds to drill a hole.
Thanks for the tip about marking holes where you want them to be. I was randomly drilling holes all over and didn't understand why the bracket didn't line up.
Haha
To clear the holes and get rid of dust you can insert a 1-2ft.-long piece of 1/4" pex tubing and simply blow all the dust out. Much easier and faster than vacuuming ;) Thanks for the videos!
That’s a good tip. Thanks
Or suck out the dust with a mc Donald's straw
It tastes better than mcdonalds toooo
I also use Bosch multi construction bits. Work really well with battery drill, and much of the time don't need to use hammer function anyway.
You saved me $150-$200. I was about to go buy the hammer drill, however your video gave me the confidence to get the work done with driver drill!! Thank you, really appreciate your advice!!🍻
I'm so glad to hear it.
you would still want a hammer drill, if you have a big project, eventually your cordless drill will crap out.
If you're going to spend the money skip the hammer drill and get a small sds plus rotary hammer. Drill holes faster and you can switch off the rotation and use chisel bits
I’m having a hard time getting the provided masonry drill bit that came with concrete screws to drill trough an outdoor brick area. Using a 20v dewalt max. I tried applying a lot of force into the drill but hole is like not even halfway
You can have a hammer drill driver
Great video. Thx!
I resisted getting a hammer drill for a long time. I needed to drill into concrete on occasion but not often enough that I thought it justified buying a hammer drill. I was wrong. Drilling into concrete is fun with the right kind of drill. More importantly, if you intend to use Red Head anchors you need a hole fairly close to cylindrical. The ragged hole produced by a non hammer drill may not be smooth enough. It is true that for smaller holes, maybe less than 3/16 of an inch a regular drill works OK. For 3/8 inch holes a regular drill might work if you are on Mars and can't get a hammer drill. But, if you're on Mars, you need to drill a half inch hole or larger into concrete and you can't get a hammer drill, just give up and enjoy the time you have left.
I had a project for a customer last fall that required me to drill several holes in very old concrete. After trying to use my regular drill and several bits later, I decided it would be much easier to rent a hammer drill and it was a wise decision for sure.
Sounds like it worked out in the wnd
@@StayHandy Yes, it did work-out in the end, but even with a hammer drill, it was still a chore to drill holes in the old concrete.
Concrete hardens with age.
thanks for the tip!
Sure thing!
thanks, very helpful
You're welcome!
I came here because I bought a 20v cordless drill and it just got delivered today. Never used a drill until a few hours ago and I want to mount a TV on my concrete wall. I'm giving this a try tomorrow and I pray it works out and I don't phuqq myself up 😂 fingers crossed 🤞🏼
How’d it go?
Really nice video. Can you comment on where you got that pergola? That's exactly what I'm looking for. Thank you!.
Thank you for the video. Where did you purchase the pergola from? It looks very nice!
Great video very informative for a novice. What make/brand drill bit do you use?
Thankyou
Look forward to your response 👍
Thank you so much for sharing this. I only need to drill a couple holes to install a handrail and didn’t feel like purchasing a hammer drill.
You're welcome!
A smart person evaluates the situation . If you find you require tools that shorten time on the job and you defo will use on many jobs then go buy that tool . I got my big rotary SDS hammer drill and that pounds big holes 24/7 . If I’m doing the odd hole then I’d use the cordless . If you doing these anchors all the time then go bigger than a powered small hand drill ,go for a big SDS , my Bosch I’ve had for twenty years and minimal maintenance( just brushes and a bit of grease ) and it’s punched holes through bank vaults ( 3.5 ‘ reinforced concrete) . No am not a bank robber , we turned an old bank into a dentists. Mad thing was I used a 3ft drill bit and still didn’t punch through
This video just in time for me! I need to drill four holes to anchor my lean metal shed, I’ve been considering to buy a rotary hammer drill since it’s what I saw in some other videos, but it’s kind of waste to buy a hammer drill just to use once. I’ll try if I can use the normal power drill to get it done after seeing this video!
Yes. Give it a try and if you absolutely need to, then buy a hammer drill.
If you haven’t bought a hammer drill yet… get one at Harbor Freight. They’re about $95 and if you’re gonna use it just once, it’s better than buying a brand name for triple that… at least this is what I did and was well worth it for my project.
;;;;;;;;;; 2 Esdras2: 31-100 '''''''''''''''''''''''' ;;;;;;;;;;;;;;;;
Did it work?
I have a fish pond with 2 closed off concrete walls on the side that trap rain water. I was gonna get a saw but I think I can makensome drainage holes now with the right drill bit. Thank you! Hopefully this saved me some fundsol
Go for it!
Nice drill!
That was very informative, thank you. I likes the tip about correcting the position of the hole.
Sometimes it’s a bit hard to put all your weight on the drill, though, like when you’re drilling high on the wall from a ladder, or in the ceiling. Recently I had to drill 6mm holes in the concrete ceiling and even a hammer drill didn’t do the trick, I had to use a rotary hammer.
Makes sense. Thanks for the added perspective.
Do not push at all
I have listened to this guy do presentations on how to start a businesses!
Were you on the recent webinar?
@@StayHandy fortunately, I signed up, but the link went to the wife and I missed it so, I listened to it after the fact.
If you want to get more than 2 or three holes from your drill bit, have a bucket of water handy, and dip the drill bit into it every so often. This keeps the bit from over heating and loosing its temper. I also use a cold chisel punch to start my hole. This keeps the drill bit from wondering. Simply place the punch in the correct location and smack it with a hammer a couple of times. Also, if you are drilling into brick or concrete block, it is best to not use the hammer function, and it will blow out the back of the block like an explosion.
Good tips
so first thing, i have a tight budget for hammer drill and im currently only using just regular drill...so with various of other comments here...well i personally think choose the tools that can be supported by ur budget..anyway the videos really did helped me to drill through concrete walls with regular drill and masonry bits...maybe in the future if my budget allow ill equip a new hammer drill soon...thanks
Thanks for using the same model of drill i am looking to use. Lots of experience using sds and rotary hammer tools, but this job is independent and required only what i own. I know i can kill (3) 3/8" anchors at 3" dewp with my tool and not kill it
Purchasing cheap off brand sds+ rotary hammer drill is never bad idea.
Cheapest rotary hammer is infinitely more productive than hammer drill.
You have to put a lot of pressure to do anything with it and it will quickly wear out your drill and drill bit.
@@Georgggg the job went poorly. I spent 2x 5/32 bits to pilot, and 2x 1/4 bits to size the hole. Burnt, blued and destroyed all 4 bits. 5/16 x 2-1/4Tapcons failed, driver was stripping the heads off before they made it 1/4 depth. Went back for wedge anchors 1/4 x 2-1/4 and they performed.
Yeah... I was really missing the Bosch bulldog, or the DeWalt battery SDS, that I've used with other contractors... Rough day!!!
@@Georgggg to all readers: the harbor freight sds hammer would have been worthwhile for the labor I put in to the DeWalt drill with a 4ah battery
Is the cordless drill put into hammer action or is it set to drilling mode ?
great video
Thanks!
Good video
thanks God bless
a protective eye gear is a must while drilling into concrete considering the dust and small particles
do you think this is also doable with an 18 or 14 volt drill?
subbed - good content
Thanks!
I used to do with a cordless no hammer drill for convenience, and now I’m straight getting an extra wired hammer drill. It does the work in seconds instead of minutes, and my neighbors prefer a short burst than a long wiring sound
Buying a good DeWalt SDS hammer drill was one of the great purchases of my entire idiotic tool collecting life. It all depends on how many holes you need to drill, how big the holes are, and how hard the concrete or stone is. I have drilled probably thousands of holes in masonry. You can definitely just use a regular drill with a good sharp masonry tool bit. Slow and dreary but it does work. The next step up is the basic hammer drill. They are a bit faster but also super loud and vibrate like you can hardly hold on to them. I wore out a really nice Bosch corded hammer drill so ended up buying this very sweet cordless DeWalt SDS rotary hammer. Cordless I say! OMG so fast, a fraction of the vibration, so much quieter you can actually not use ear protection, I am not kidding. Also it will just a hammer, miniature jackhammer which is fantastic. Constructed walls in my basement had to drill about 50 holes into very old concrete. It was a real true pleasure using this new drill. If you just need to drill a few holes on one random project then yeah go ahead and buy masonry drill bit and have at it. I can give you about 20 of em I don't need the cursed things I have all SDS kit now.
Thanks for the insight!
Gr8 info
Does it work in black top?
I have DeWalt DCD796 hammer drill and I am struggling to to drill into the ceiling of my apartment which is made of concrete/cement. Any Tips?
If using a regular drill for using it on concrete brick what setting should I have on ?
Great video. Anyway, I am interested building a pergola like the one on your video. Where did you purchase it? Thanks
The customer purchased it from Costco
Hi, great video. For a similar project where I have to install a metal pole to anchor a sail shade to, how can I drill perfectly straight into the concrete at a 90 degree angle?
Either a drill press or a decent level of skill using a drill
If you're mounting a plate with multiple holes, use the plate as a jig to start the holes in correct orientation to each other after getting at least one accurately started by eye, marker and/or punch.
what about impact drills?
Excellent informative video for this DIY guy and the simple project in mind. Thanks! One question. You don't use some sort of cement epoxy when installing the bolts?
👍😉👌
No
Just about to install the same pergola. Do you remember which drill bit you used? Also would you recommend using a tapcon kind of screw instead of an expanding anchor. I have read lots of people had issue getting the provided anchor to grip in the hole. Thanks in advance
I don’t remember. I believe it was 9/16. Also, just don’t over-tighten or use too big of a drill bit.
Can you share where did you get your pergola?
Masonary bits are horrible. I only needed to drill two holes in my garage for some garage door sensors. It seems like the bit dulled almost halfway through the first hole that I needed to drill. Had to use so much force and took twice as long as what you demoed with your ordinary drill. Mine was a Ryobi 18volt drill with a heavy-duty lithium battery. Maybe the bits I got from Home Depot were poorly made also by Ryobi.
Any recommendations on speed when using a regular cordless drill, and should I worry about the drill bit getting too hot?
I don’t worry about either.
Using the cordless drill, which is more beneficial?...using the gearbox in speed 1, or speed 2?
And as well, which torque setting? My Ridgid has 24 stops and the aforementioned two speed gearbox.
I am drilling 4 holes in concrete porch to install a handicap railing. Thanks.
Same question. I destroyed some drill bits and still don’t know
You have a cordless drill and you want to drill a half inch hole in concrete, first of all it is the wrong tool for the job, not that it cant be done, you can, you will have to put a lot of pressure on the thing, so low speed and maximum tourgh setting. If you are smart you start with a small size hole drill to the needed depth a, go up in size from there, use quality drill bits if it is more that a few holes you will have to make. If the drill gets warm/hot let it rest for a while, read the manual about duty cycle, don't be surprised if you can only drill for 5-10 minutes and then let it rest for 30-60 minutes, you see it is not the best/right tool for the job, sorry.
Yes you do ! New concrete is far easier to dril than many years old concrete. Many other factors come into play as well.
Make a video then.
Some old concrete that was poured back in the 20th century simply can't be drilled with a regular drill, especially larger holes. It has to do with the amount of crystalization within the concrete. New concrete that was made with high water content and allowed to dry very fast has lower crystalization and is more like styrofoam compared to old concrete. The concrete in this video looks newer and 'builder grade' (cheap and fast).
Thank you for this, highly appreciative. Thoughts on drilling into granite ?
Try it without the hammer function first, then if you need it, use the hammer function.
I just drilled a hole in old concrete with a 3/16" x5 " bit .. for a 1/4" x 2 1/2" tapcon. for some reason that tapcon doesn't want to go all the way into the hole. Maybe i pushed too hard on the drill and it slightly warped the bit while drilling? would that cause issue with the tapcon going in? I like your tip on using the drill w/ bit and vacuum to clean . I did clean out the hole but used a little brush and canned air. any ideas on what went wrong and why the screw doesn't want to tighten down into the concrete? thank you
Most likely you need to drill deeper. Drill at least .25 inches deeper than you need then clean out the dust thoroughly. Go deeper if it's not an issue just to be safe.
Sometimes, broken rock debris jammed in the bottom of a hole that won't blow out can be a problem. That's where the drill combined with a vacuum can help. Probe the hole with a rod that's small enough to fit loosely to find out.
Can you do a demo drilling into a concrete wall, at a height of, say, 2 meters? For, say, attaching curtains rails?
how to insert the diamond coated milling bit to the drill?
Doesn't that 20v Dewalt have a hammer function on it too?
I know mine does.
You can drill a hole with out the hammer function however u will need to replace your bits quite often because the bit will overheat even while spraying water
thanks.
Got a cordless hammer drill from Aldi here in England, works great for going into concrete
Try the SDS version and it's way, way faster.
@@typhoontim125 yea that's the one
@@konstantine381 Great...Sds is on another level...and no loosening of the bits...and being from Aldi, incredible value.
what is the brand of the pergola you installed? @handyman startup
Paragon Outdoor. The customer purchased it from Costco. Seems good. Looks like I'll be installing one for their neighbor as well.
How do you use "pretty much all of your bodyweight" when drillng a hole on a wall? 🤗
Impossible, but position yourself as high as possible, at least at chest height to be able to apply your shoulder, chest and arms weight.
Hi I Like your info what’s the name or make of the Pergola in the video something I’m looking for. Thanks in advance.
Check the description
Thanks for this video. I don't have a hammer drill but do have regular and impact drill. Which one would be best for concrete with masonry drill?
Hammer drill
@@StayHandy Tks, but my question was if I only have a regular drill and an impact drill, which one of those should I use (since I don't have a hammer drill)
@@raekc4839 If you only have a Standard (Regular) Rotary Drill and an Impact Driver Drill it is best to use the Regular Rotary Drill to make holes in brickwork or concrete. Just make sure to use a masonry drill bit and take your time. The main difference between a HAMMER Drill and an IMPACT DRIVER Drill is in the way the machine drives the drill bit. A HAMMER drill will push the drill bit forward in a pulsing fashion to break up the material, where the IMPACT DRIVER drill pushes the drill bit around in a circle in a pulsing fashion to seat the fastener. Not the same thing.
Keep in mind, you could use the Impact Driver Drill to drill small holes in masonry - up to say a maximum of 1/4 inch. But you might as well use a Standard Rotary Drill in this case. It will do just as good a job.
Of course, nothing beats a HAMMER Drill for drilling holes in masonry though.
If yout using expanding anchors it doesn't matter what kind of drill but if your using tapcons your less likely to wallow out the hole with a hammer drill and the screws will hold better. Also if your not using a hammer drill your goi g to wear out the drill bit faster.
Thanks for the additional perspective, Chris!
what settings etc?
Can I ask why you prefer driving in your fasteners with a ratchet opposed to an impact driver? And I’m going to be installing some stuff in my garage this spring with some tap cons and I’m not looking to get the job done speedy, is it safer to use a ratchet to drive in the tap cons?
I think it’s safer. I like to be able to feel the amount of torque I’m applying so I don’t over tighten.
@@StayHandy Absolutely. I had used the 12v Dewalt impact driver to tighten and broke couple of tapcons in half.
@G8 Beast a good impact driver with good trigger control like the metabo hpt triple hammer is awesome for this.
I go about 3/4 of the way with impact drill, then last 1/4" with wrench.
Great video question how do you drill a 3” hole in concrete that’s 7” thick wall
There are special hole saw drill bits for concrete.
I needed to make 3" for ac lines and I had to make many 1/2 holes around the 3" circle. It took me an hour. I couldn't afford $75 for 3" hole saw.
I only have a regular 18v milwaukee drill. I've been wanting to put some screw in my concrete wall but it's hard for me. Should I just get a hammer drill? I can't seem to get the screw into the wall 😫 Just a stay at home diy mom trying to hang some things up on my wall 🤷♀️
Do you have a fresh concrete bit?
You didn't mention any settings on the cordless drill itself.. would have been nice :)
Tip: use a drinking straw to reach the bottom of the hole with the vacuum and clamp your hand around the vac nozzle and straw top.. it's way easier to get the dust out.
Thanks for the tip!
Good luck at my house with that. My grandpa used the same concrete for the foundation and cellar walls that he used to build bunkers with during WW2. Even when using a hammer drill and good Hilti bits, the concrete sometimes just turns white. When you manage to finally drill the hole, the bit is relatively fcked. xD
The drill motors you show all appear to use a normal Jacobs type chuck. The drill bits you link to are all SDS bits. Can SDS bits be used in a normal Jacobs type drill chuck?
That was a mistake. I’ll change the link.
@@StayHandy The drill bit you link to is still an SDS bit.
To answer "Can SDS bits be used in a normal Jacobs type drill chuck": No not directly, you can with an adaptor but those I have used need a chuck that opens up to a bit more than 13mm (1/2").
Will 12V dewalt work as well? To make small holes for screws?
Try it
1. It is not really easy to drill to concrete WITHOUT the hammer function specially when drilling holes to the wall or concrete soffits. Try "applying" your own weight on those.
2. Forcing your cordless drill to this concrete, and then doing it several times, will wear down your battery even faster which will require you to charge more often. It is interesting to see how many holes the cordless drill without the hammer function can finish with one charge(considering the battery capacity, of course)
3. It is also interesting to know that hammer drills will make your work faster and more efficient in this kind of situation.
The hammer function is designed to some drills, corded or cordless, for a reason.
Sure the non-hammer drills will get the job done as seen in the video. But if you want efficiency(specially if you are drilling a lot of hiles on concrete), you may want to consider affording a hammer drill.
It is not that you don't need a hammer drill per se.
But it is about considering the right tools for the right job.
Right, you don't need a hammer drill if you consider your drill to be 'disposable'😂
Exactly. If I had less than two holes to drill and no hammer drill, I'd proceed carefully, cooling the bit frequently and using the bit as a chisel to break any rocks encountered by hand. If I had more holes than that to drill, I'd stop and get the right tool.
I have a good idea - use an SDS drill and drill the hole much quicker, smoother, quieter and a lot less wear on the drill and bits.
just used my cordless drill no hammer drill couldnt barely get 1 in deep, was afraid bit would break with to much pressure. gonna get a hammer drill wondering if a cordelss hammer drill would be as good as a corded hammer drill?
Not usually. The dedicated corded hammer drill is going to be better. If you have really hard concrete (concrete hardens with age) then a rotary hammer drill is even better.
@@StayHandy what’s the difference between a hammer drill and a rotary hammer drill?
some ppl said to me that when u drilling concrete without hammer drill feature, it still can be done but it will damage your hammer drill, is that true?
What is "hammer drill"? is it the machine itself or the drill bit?
Cheap drill bit will get dull /damaged fast, quality bits will last longer. With and without hammer is two very different types of drilling techniques. Without hammer you are scraping/cutting into the material, with hammer you are crunching the material, so it is two very different aproches to get the job done.
if you are on a budget then what I would recommend is to buy a corded hammer drill. its not that expensive compared to a regular corded non hammer drill but makes a huge difference in my opinion because you cant always use your body weight in every situation. sometimes I drill way high up or in weird places where I cant use much of my body weight. And obviously if you are drilling multiple holes, you'll feel tired because you are also doing some of the work which the tool is not doing. Also bits gets duller quicker and less effective without a hammering action.
if your home is made using bricks and concrete then I suggest leaning towards a bigger rotary SDS type drill because those things works super well. They have much slower RPMs but the actual hammer effect is way higher. Since they spin slowly and have a better impact, the bits will last much longer as well. However these drills will use a different type of drill bits which you can slide in and you cant use other drill bits for example when drilling wood or metal without an adaptor. Most SDS drills will come with this adaptor but I think you can buy separately too. with most SDS type drills you can also select what you wanna do. you can just use the rotary action or just the hammer action or both at once. great if you wanna break up tile or small stuff like that.
if you got the money then what I recommend is to get a cordless normal drill + a SDS drill. owning just ONE drill is not that ideal because lets say you just got the SDS drill, then if you wanna drill metal or wood you have to use an adapter, then another drill bit. but if you got a cordless one too, then you can use that for wood or metal. I think all cordless drills comes with a keyless chuck so its easy to switch bits too.
another advice is you can rent and see before you actually buy the tool. just rent both drills and use em for a while and see the difference and see for yourself if paying more is better. In my case I own couple of normal drills and a corded hammer drill. When I need to drill a lot of holes I just rent a SDS drill. For now I don't have that many use cases to own one.
Depends on the concrete. The concrete i had to drill had really hard rocks mixed in. At some point it stops drilling, the bit heats up and it wears out.
My concrete wall has small rocks in it. Will an expensive concrete drill get through that, or am i just out of luck?
@@edntzA hammer drill breaks those rocks and continues on. That, to me, is their greatest advantage.
Rebar in concrete is a drill bit killer, but special SDS drill bit exist that claims to go thrugh rebar like butter. What happens when you hit rebar is that the drill bit can not "eat" the metal and heat starts to build up and melts away the tip of the drill bit and you are toasted. What I have done a few times when I feel I had hit rebar, I take a regularly drill with a standard metal drill bit and sacrifice that drill bit to go thrugh the rebar.
I'm a DIY person and I noticed that my cordless and good drill bits just better than I remember vs 15 years ago. I think it has something to do with cordless being stronger and modern drill bits a lot better than back in the day. still, I prefer the hammer mode as without it the job is slower and a cheap drill bit becomes too hot or dull.
Makes sense
It really does depend entirely on the frequency, size, and type of holes you're drilling into what type of masonry that seals the deal for what tool you actually need.
If you're the casual handyman who, on occasion, needs to drill a half inch hole into concrete, brick, mortar, cinder block, etc, the average rotary hammer with a solid masonry bit will work just fine. I wouldn't even blink twice telling someone to who needed to drill two holes for a concrete anchor into a brick to hang a gas cylinder bracket to use a rotary drill, even a cordless one.
If you do any sort of masonry drilling with regularity, of diameters larger than 1/2" into reinforced concrete, bricks, cinder blocks filled with cement, don't waste a second trying to use a regular rotary drill. *Find and buy the largest rotary hammer drill you can, preferably with an SDS or SDS Max chuck with at least 10 amps and 5+ foot pounds of energy and quality SDS bits that is CORDED*
You'll be legitimately shocked how quickly you'll pulverize all the above listed materials. Anyone who has large bore holes to drill on a weekly basis will attest to this. If you worked construction for any length of time and how to augur through masonry, you'd be either let go or laughed off the jobsite using a rotary drill, pressing with all your might trying to get through a single brick while the professional three walls down is slightly leaning into the wall with his rotary hammer drill bulldozing through with ease.
I've actually seen (and done in my amateur days) someone burn through two whole batteries on a cordless drill trying to drill into a cinder block nearly breaking their wrist through the effort. I walked up with the Bosch Bulldog Extreme with the notorious Bosch masonry bits and punched the desired hole length through in, no joke, 30 seconds. He looked at me, then down at his drill, and enough was said...which wasn't anything. In my opinion, Bosch and Makita make the best rotary hammer drills on the market with Bosch making the best SDS and SDS Max bits for said drills. They humiliate and brutalize masonry like it's an annoyance they're in thew way of the tunneling bit. Well worth the money.
For big holes, and a lot, you need a powerful hammer drill that takes SDS drill bits.
i wondered why their were drill holes in the concrete of the home i purchased they said they do it for termites. is that a thing that needs to be disclosed to a homebuyer?
Never heard of that
Can you use a center to indent drill hole first?
A center? One way to get the hole started is to put a couple layers of tape down and the tape will help keep the bit from walking.
