- I snapped a drill bit when drilling into some mild steel for the 2x72 Belt Grinder build. So I decided to try the new Drill Doctor 750x.

![SAVE YOUR BITS! Drill Doctor X2 Drill Bit & Knife Sharpener Review [WORK SHARP]](/img/n.gif)
I've had my Drill Doctor for almost 20 years. It's never failed me. I have found that when you sharpen a bit and then it doesn't work well like your 4th bit, It can generally be traced back to not seating it properly in the collet. Just slightly off will cause the bit to be sharpened just a hair off. placing it back in the collet and resharpening usually fixes the problem.
After watching this immediately bought a drill doctor through your affiliate link. I wish I discovered your channel earlier. You are what I aspire to be in 5 years.
I just pulled my DD-750x out of the box and, in an effort to try something new, I decided to read the instructions. That led me to CZcams for the manufacturers video and ultimately to here. This is a super hands-on, in the workshop, practical application video! I, too, recently did the math and decided I've spent just about enough on drill bits over the past [insert number] years. Fortunately, like most of the DIYers who have, or will be, watching this, I don't have the inner strength to throw away perfectly dull drill bits - even ones that snapped off just above the drill chuck (no, I won't try sharpening those - but they help tell the story). Anyway, thanks for the boost of confidence, Brian. I'm off to resurrect the contents of my shoebox and prove to myself that it's ok keep some things that appear beyond the help of superglue and duct tape!
Excellent! Glad it helped! 👊🏻👊🏻👊🏻
I have been using a drill doctor for 20+ years. I just updated to the 750x. man I love mine!
I've never had much luck with my Drill Doctor. But after watching this, I guess I'll have to try again.
Worth a shot
Position the bit properly. Sharpen some. Reposition the bit. Sharpen some more.
I have the 400, which was discontinued several years ago. About once a year, give or take, my 3 brothers, 3 brothers in law, our father and I spend a day touching up all of our bits. Awesome piece of equipment.
My only regret is that I didn't purchase the extra chuck to take up to 3/4 inch bits. Maybe I'll get lucky and find one on ebay or Craigslist one of these days.
One of the best $100 tools I've ever purchased...
I’m shocked it sharpened that broken bit, and completely convinced and sold on the drill Dr. Great video.
Yeah man! It’s been really great having sharp bits whenever I need them. Good buy for sure. 👊🏻🤩👊🏻
And I just realized you snapped a bit in the last build video. Makes more sense now as to why you would need one! 👊🏻
I have repaired dozens of drill bits with mr Drill Doctor, just ordered an updated unit to replace my hard used original.
Been looking at a drill doc for years and procrastinated and put off buying one for years…not anymore..gonna order 1 on payday cuz of yur vid sir…thanks 👍🏻
Awesome. We use it almost everyday. Worth it!!
Thanks Brian for your review. I just purchased one and plan on putting it to the test later this evening.
Mine gets weekly use still to this day. Great piece of gear. 🙏🏼
I use bench grinder first and then doc takes over. Great machine and love it 😍
Same!! 🙏🏼🙏🏼🙏🏼
Ive had the 750X for quite a few years and I love it. You have to mess with it to learn how to use it properly but, it works!
Totally agree Greg. Took a few try’s but I got it and it’s a really useful tool. It’s a tool for your tools!? 😂
I have am old drill dr still new in the box, will a have to start sharpening my bits now that I have a table. Thanks for sharing.
Heck yeah. I spent about an hour sharpening my box of throw always. Now I have all kinds of options. 👊🏻
Checking the 'exit wound." Instantly liked your style and subscribed. It's only a good deal if it does what you needed of it. The cost of damage from cheap tools is never worth the perceived savings. There are times when a HF tool will work but I've found their drill bits to be something to avoid. It's less expensive for me to buy better tools than to buy more raw material, especially when it's an expensive raw material.
Checked out the video because there's lots of spare time lately and I've had a Drill Doctor for years. There's always the opportunity to learn more.
Wish you would have done the split grind.. But this is what I am looking for.. For years I did it by hand but at 73I can no longer get it done right the first time.. so it is the drill doc for me..
I liked the comment ""Now we have a short drill bit." The good news it really worked well. I see many workman that dont know how to use a bit expensive or cheap and just go buy more. After watching this video. I am buying a sharpener and quit judging others. Ask for their discards. I just paid 13.00 for an Irwin 3/8" titanium bit. Not sure if it wasnt that good out of box or it was me. (I was drilling into a light steel fence gate no oil) However the video demonstrated the value of the sharpener regardless of bit user abuse. . Great video. Nice shop
I ordered the 500X for my use , great video .
awesome video this is why i watch u-tube thank you!
Thank you Eric for saying so! 🔥👊🏻🔥👊🏻
Nice review good teaching..
Thank you Bobby. 🙏🏼
For the longest time I thought you lives in Italy (all the espresso, boating content, end music). It just clicked that there is a a certain city in FLORIDA with the same name, ahaha. Cool vid, I sharpen by bits with a cutting wheel in a grinder locked in a vice. I made a habit to also write down the bits I break and buy new ones when I'm at the hardware store. Cheers
Haha! Yeah man Florida Naples, not Italy. That’s a good idea on writing it down when you break one. I’ll have to try that. In any case this keeps me from having to run out of I do need a specific size. Merry Christmas my Friend! 🎄🎄🎄
I've been thinking about getting one of those! Happy to see it works well. Wish it went up to 1'' though! I have some big (expensive) bits that are dull as a butter knives. I abuse a lot of my bits... I've found pretty good deals on ebay if you're looking for bulk twist drills in a specific size. I use a #13 drill for my corby fasteners and I think I have 25 of them! Same with 1/4''. Have a merry Christmas!
Thanks J! I was skeptical about this thing, I had been burned by the Onion sharpener made by the same Corp so I figured this was a bit of a fad. But the Amazon reviews seemed genuine. I may only use it a few times a year but at least I won’t be throwing out bits. It’s definitely worth having in your workshop. As always I appreciate you and have a Merry Christmas!! 🎄🎄🎄
Great video Brian. I would say I'd ask Santa for a drill doctor..but he's already been and gone for the year. Great info and presentation. Some bits of info I've gained over the years, that I'd like to add to your info: make sure to use cutting fluid when drilling, take into account the specs for the material and depth of cut as well as specs on the type of bit you are using. And when I say specs, I mean hardness of material, material composition, RPM speed/rate for drilling, as well as what the bit material is recommended for. Also make sure to not overpower the bit when drilling..you can dull or snap a bit quick doing this. Let the tool do the work. Just "bits" of info I've had to learn the hard way over the last 25 years. LOL Merry Christmas to you, your family and all of your followers!
I started using Tap Magic and that stuff definitely works. Maybe I’ll do a vid on this subject alone. The things we don’t think about when drilling a hole. Just a thought. Hope you had a great Christmas! 🎄🎄🎄
Square up a broken bit with a bench grinder or cut off wheel. Remove stock to the approximate angle, reliving the backs. Use the drill doctor.
Week that's very impressive. I'll drop off some bits next week for you to sharpen 😆😆😆bMerry Christmas Brian 🎄🎅🦌⛄
Haha! Yeah man, come on by! 😎
Merry Christmas to you too Marshall!! 🎄🎄
Wow Brian you are the "Emeril" of the home tool mavin. You should be on Public Broadcasting Channel.
Great explanations. Easy to follow. Thank you for the help (yeah, I've got a Drill Doctor too.
Hi Alborg, thank you so much for this wonderful comment. I really enjoy doing this work. And supporters like you make is all worth it. Thanks again.
To sharpen a broken off drill bit, I simply take it to a wheel grinder first. I point the bit directly at the wheel and push the bit straight into the wheel to grind away all of the damage giving the bit a flat end. That way little spring grippers on the Drill Doctor properly position the bit when you put in the the Drill Doctor's chuck. (I know your way eventually worked, but as we could see, you had to readjust the bit a few times).
I've seen a few videos on the drill doctor, they are about 50/50 people either love them or hate them... I started buying Molybdenum bits, which seem to last longer. Though most of my drilling is 1/4", so I just bought a 10 pack. Definitely have the bin of dull bits though, hahaha... Hope you and your family are having a great Christmas. Take it easy.
Thanks Dave, yeah man. I’m in the 50% who loves it. It’s really useful for me. I’ll have to look up Molybdenum. Never heard of that! Always learning something from you. Merry Christmas to you! 🎄🎄🎄
@@HouseMadeUS Just be careful if you get some, with metal, they'll grab & pull it right out of your hand. They are a little tougher than Cobalt.
Good info. I try to clamp everything down but sometimes I can’t do that every time. They sound tough. 👍🏼💪🏻
@@HouseMadeUS I have a built in reminder a scar down the center of my left thumb where i split it with a piece of steel that spun as the drill broke through. Saved time? Not if you count the time in the emergency room and the cost.
Accidents? There is no such thing. Should be called a stupid mistake.
What’s going on sir Brian lol?! I hope u and ur family are having a fantastic Christmas Day!! And I’m definitely going to order one of those now after seeing this!! And honestly bub the real expensive drill bits don’t last much longer then the cheap ones! When I was doing mechanic work for my dads company I had a set of bits that costed me like $50-$60 and it was a box of bits like that one u have, that comes with like 20-25 bits or something like that and then the head mechanic had a box of bits that same size that he paid like $200 for or something like that and my bits lasted almost as long as his did!!! But it looks like that drill dr worked pretty damn good!!! Hope u and ur family have a good rest of the Christmas Day!!
That’s a good point Mark! I wonder how many people have had the same experience. I’ve only really used cheap bits so I can’t comment. Hobo-Freight has had some deals again this Xmas. Like $10 for the big box of bits. It looks tempting!! 😂😂😂 Hope you’re having a great Christmas! 🎄🎄🎄
House / Work yes sir we had a great Xmas thank u!!! And yeah it’s hard to pass up good deals on tools, I know exactly what u are saying there. I just can’t justify spending that kind of money on drill bits or tools in general! Ya know I can go buy craftsman tools for a quarter of the price of snap-on or matco tools and craftsman has the same lifetime warranty on their tools as snap on or matco, and I never ever had an issue returning a broken tool and getting a new replacement for it!!! So why pay 4 times as much for a tool? I Just don’t get that at all!!!
From what I’ve read, coated bits will wear quickly once the coating is removed by resharpening. Cobalt bits are not coated and will return to their original durability if resharpened but they are not cheap.
Yeah that makes sense. I’ve always wondered what that ‘titanium’ coating is. I’ll keep an eye on it and see if I notice any issues.
That drill dr is more like drill necromancer reviving bits from the dead
I like your oil dispenser, can you share its part# and which oil you use? also I'm pretty happy with my old DD500, works well so far
I've come the conclusion that my drill bits aren't "dull"... they're just lazy.
My drill bits definitely have a low IQ. Or perhaps thats the operator? :)
I have several broken SDS hammer drill bits. Do you think these could be sharpened on the drill doctor, and made into a "regular" drill bit? Just an idea I had. Oh by the way, I just purchased the DD750X using your link, as well as a hard caring case to keep it safe as I travel from project location to project location.
Yes I think that would work. The coating (if any) would be removed but they would still drill just fine. I do this all the time.
HF has a lot of good stuff, but drill bits and taps are not among them. I have a drill doctor and it works great! Going to sharpen a few of my bits in the morning, in fact. Thanks for sharing.
So did you get to sharpen your bits yet?? 🤩 I appreciate you watching and joining in. I’ve used this dang Drill Doc about 10 times since I’ve made this video. Great purchase.
@@HouseMadeUS just got done with a half dozen. Ready to go, now!
Hell yeah man! Nice work! It’s best to do them in batches. 😅
I agree there butter
Would like to see you use the Drill Doctor make split drill bits.
That would be interesting.
Titanium drill bits are for suckers!
Once you wear through the thin titanium coating, the rest of the bit is just steel. Carbide drill bits are carbide all the way through!
I have had the Drill Doctor model 500 and model 750 for years and if something were to happen to either one, I would immediately buy another.
Here's a couple of tips: 1. Drill alignment in the chuck is everything. 2. don't fully tighten the chuck until you have carefully removed the chuck from the alignment port. If you fully tighten the chuck while in the alignment port, you can change the angle.
All good points! Thank you! I'll give that a shot with my drill doc.
I made a mistake. I said carbide when I meant to say cobalt. Cobalt drill bits are not made of pure cobalt, but rather a steel alloy with 5 to 8 percent cobalt. The 5-percent alloy is known as M35 grade, and the 8-percent alloy is M42. The cobalt increases the strength of the steel and makes it more heat-resistant; this is an important factor in drilling hard materials because the friction of metal against metal can produce high temperatures that damage the material or the drill bit. Bosch, for instance, makes a cobalt drill bit that can withstand temperatures of up to 1,100 degrees Fahrenheit (593 degrees Celsius). Cobalt drill bits are cobalt alloy through and through and not just a coating like titanium bits. For this reason, they can be sharpened relatively easily with cutting fluid while retaining their strength and durability (although the gold color may wear off).@@HouseMadeUS
I'm a machinist. Carbide sucks in a hard material. Cobalt is best
@@donjohnson7899 You're right! I apologize! I meant to say cobalt and I just plain screwed up. Thanks for correcting me!
How are you aligning your drill bits? Has anyone tried advancing the drill bit towards the plus mark to the left of center?
I can align them pretty well. I’ve not tried anything but the standard alignment. Still use this a lot.
@@HouseMadeUS so you just use the center alignment thats marked 118?
What happened to the 2×72 belt grinder project?
I’m traveling for the holiday to see family, this was a pre-recorded video. I’ll be back at it on Friday.
I sent you the message by accident. GMG is Green Mountain Pellet Grills.
Ain’t no way the 1st bit you sharpened was 3/64” or less than 1/16”. I’d guess 13/64” ?
Would sharpen to 135 degrees & split the point for tool steel drilling.
Good tip. I've been using 118. I'll try 135
wonder how long the drill doctor will last before having to be replaced? can you buy a new or extra grinding wheel for it?hmm!?
Yeah they diamond wheel is replaceable. It feels pretty solid so maybe it will last longer. 👊🏻
Yes you can buy a new wheel. The bad news is that it is about $20. Carbide drill bits?
Frankly, the only ones I own are for cement. No precision needed.
update your links brother
Thank you. Will do. 🙏🏼
Harbor Freight does have some good stuff, but I always avoid anything that cuts. They're invariably cheese grade.
Surprisingly the end mills are pretty good.
That doesn’t look like a 3/64 bit too me
"Twist drills"
i just bought drill doctor for 149.95 from link that you have in your on your channel . also i bought General Tools Drill Grinding Attachment #825 - Drill that i find my self .. please message me when you got commision i just want you must got it by the way nice channel...⚔
Your video ie way more helpful than GMG.
Thanks I appreciate that. Who is GMG?
I have a drill doctor 750X, That the tiny grinding wheel in it takes so long to sharpen large drill bits, and the motor has little power for the big bits. Forget sharpening large carbide bits, you would damage the little sharpening wheel.It's best for smaller bits that are just dull not broken.
NOTE: you can buy a lot of drill bits for $150 and save a lot of time.
That is a good point. I usually sharpen my bigger bits on my belt grinder. Thanks for watching and commenting.
Get the coarser wheel for larger drills.
The only thing bad about the HFT drill bits is the heat treatment which makes them on the Brittle side but for $9.00 you just can't go wrong, I have three sets around the bench & use my Drill Doctor to sharpen them. But for really hard metals especially small diameters I prefer M42 cobalt drill bits but you need to keep them cool but they will drill through Spring or Hardened steel with coolant.
