- In this video i will show you how to sharpen a masonry bit to cut harden steel
I will demonstrate drilling into hardened steel with a cheap carbide drill bits
this works well for drilling in to knives or knife making

I knew you could do this, but your video showed it well, thanks mate
Thank you for your nice comment and thank you for taking the time to comment. It is much appreciated.

Nice demo.You didn't talk us to death like some do.I like that.I have dulled many bits drilling hardened steel.Now I can do it the right way.Thank you and looking forward to more useful demos.
Tests like this are a great use for 9mm wrenches.
Surprisingly wrenches are not that hard.
I have other videos where I drill a top out and also drill through 50 some Rockwell.
The latest video I’m drilling through an end mill.

Great info. Your attention to detail is what makes the difference between success and failure. Following your procedure also gives (most importantly) repeatable results,,,,the best kind of results. I have a blind hole in a piece of turning stock that inadvertently became ‘work hardened’ through the use of a cheap drill. I now have a viable and repeatable method to drill past this zone in my work piece.
Thanks
thank you for your comment and sharing your experience
comments like your puts fuel in the creative gas tank

Wow. I never knew that but I had 4 case hardened steel parts to drill an oil hole in and the masonry bit worked like a charm. Took only 5 minutes to do 4 pieces.
That’s excellent
Thank you for sharing your experience much appreciated and thank you for commenting that really inspires me to create more contact
Thank you
Ray
Great tip and I am sure to use this some time in the future. Thanks for the video.
Good demonstration very useful tip to know. Cheers Tony
Thank you for the nice comment and thank you for taking time to comment. It is much appreciated.
This is legit. I used one of these bits to drill out a broken bolt that had been work hardened to a point that nothing would touch it.
Thank you for sharing and thank you for taking the time to comment. It is much appreciated.
Worked like a charm Thanks for the heads up! My first try I had it too pointed but once I flattened it out just like he said I was drilling holes :)
I am glad that this worked out for you
Thanks so much for sharing your experience it is much appreciated
Ray
Brilliant bit of information 👌 Thank you for sharing 👍
Glad it was helpful!
Thanks for this! Was drilling hardened steel yesterday and dulled too many bits. Next time I'll know what to do!
thank you for commenting
Ray
Your lesson helped me a lot!
Thanks
I’m glad that it helped and thank you for taking the time to comment. It’s much appreciated.
i did this trick and bam worked like a charm and i tryed just about every thang thank you sir for your expertes
Thank you for taking the time to share your story
Much appreciated
Ray
Congratulations ! Very usefull, thank you for your excellent explanations.
Thank you for your very kind comment
Ray
Good job Chief!👍👍
Thank you for the nice comment
Ray
Thank you for Good information...^^
From South Korea..
thank you for commenting

Amazing. Will try it to drill out a stuck bit in impact driver. Edit: used an unsharpened masonry to drill. It worked well and my drill operational again.
let me know how it works for you
ray
@@michaelcook4922 i got this b4 others got to it. It looks hit and wedged in real hard from previous attempts. I dont think magnet will work, but I'll try. Cheers
Thanks, I've been know to break taps and not have a carbide bit to drill them out. Masonry bits are widely available and cheap. I'm not as steady as you are so I'll try sharpening a masonry bit on my Deckle knock off tool grinder.
You should have more subscribers!
thank you for the comment
it just takes practice
you can do it
i usaly use a carbide end mill but the drill press is not ridged enough and will snap them
Ray
@@shopandmath I don't have a full set of carbide end mills. I use the mill instead of the drill press when ever possible.
@@shopandmath carbide ball mills actually do ok at removing taps for non rigid setups the ball curve helps protect the carbide
thank you very much. it helped me a lot
Thank you so much for taking the time to comment
It’s much appreciated
Ray
Destruction for "positive" purpose is good. please keep your great work continue.
thank you for the nice comment
Ray
GREAT JOB
thank you
Just wondering what rpms was the drill turning at. I drilled hard steel last week with a masonary bit , but the package said good for steel too. Able to do rebar, I guess. Any way, I had 4, 3/16 holes to drill though 1 1/8 diameter hard steel. It worked but took about 2 plus hours. With a hand drill. Could not get the piece in a drill press. I used rapid tap oil. Masonary bits work. But in my case it was hard pushing. Thanks for the video.
You are the second person to ask about drilling hard material with a hand drill
I am currently in production of a video to drill hard material with a hand drill
I am currently swamped with school work
Hopefully Video will be posted either this Friday or three Fridays from now because next Friday’s video is on glass cutting
That amount of time is unacceptable and should have cut a lot faster
The piece I’m going to be cutting I believe is 49 or 59 Rockwell I film the hardness testing three weeks ago
Did you sharpen the drill to resemble a spade bit?
Did you also re-sharpen after the tool became dulled?
Do you use a guide to drill the hole perpendicular and also to prevent angular movement during drilling?
Hold tight the video should be up in a couple of weeks
Thank you for your support and comments
Ray
Can you do a video on indicating work pieces on OD and ID for the cnc lathe?
Great idea! I wonder if you could you do the same thing with a Drill Doctor? Drill Doctor doesn't recommend sharpening drills smaller than 1/4" but for larger drills it works reasonably well. I have a broken 1/4" tap that I need to remove so I think I'll try sharpening a 3/16" masonry drill even though it's not recommended, then see how it works.
I removed a broken 1/4-20 tap in a the video (remove broken tap) Video link
czcams.com/video/rSShHH2Us5Q/video.html
I tried to brake it in the drill press but i could not do it
so it got the hammer treatment
the sharped drill in this video was what i used to drill it out
Ray
Carbide will tear up your wheel on the drill doctor. You need diamond to sharpen carbide.
Fortunately there are cheap diamond disks and wheels available nowadays...Some are very expensive...the one shown here is probably around a hundred dollars new but the ones he showed will do the trick also.
I really enjoyed this video and would love to have your thrift store in my town with 50 cent new craftsman wrenches and 5$ diamond wheels~!! I have always wanted to try this so I think I will now after seeing your way of doing it.
thank you for your nice and positive comment
Ray
@@shopandmath UR Quite Welcome~!
Would this principle work on the bigger masonry bits like 1/2 and 3/4 and so on? Do you calculate the RPM for these as 80x4/drill dia or do you use other numbers?
I have done this with drawls up to 3/4 of an inch with great success
Under ideal current conditions you can use probably up to a 300 CS
In the type of demonstration that I showed in this video the set up is not rigid and you would have to drop your CS down to probably 50 to 100
I hope that this helped
All the best
Ray
Thank you that awesome
Thank you for your nice comment and thank you for taking the time to call me it’s much appreciated
Ray
nice tip
thank you
100% - but will this work for enlarging and existing hardened motorcycle sprocket 8.5 mm bolt hole to 10.5 mm? Cobalt drills aren't supposed to work as the central web isn't big enough so they will likely grab and snap; and even if not the sides of the cutting faces in contact will just blunt after one or two holes?
Carbide generally outperforms cobalt. The only factors are the quality of sharpening and the angles.
The more rigid, the set up the better the carbide will perform
Great video! Could you share the specs of the diamond wheel you bought of ebay? Thanks! Fabian
that under cut could be made with the drill held in a vice and use a small diamond wheel on a dremel.
That’s a good idea. I will have to try that one time.
If drilling through thick aluminum, how long should the bit stay in contact before lubing and clearing shavings?
Also, how much downward force should one use to not burn up the bit?
I've used a few HHS jebbsen bit and some other bits but nothing seems to make a hole bits keep braking.
What are you drilling into?
It depends on the type of steel I have another video which basically does the exact same thing or a drill into a tap
This method does work relatively well there are a few things you have to keep in mind the diamond wheel I’m using puts an extremely sharp edge on the tool so that’s a bit of an unfair advantage
I am also drawing into something that is flat so if you’re drilling into something that has a bumpy contour onto it that you cannot flatten out you’re going to run into problems with the chip not fighting right away and wandering that could be a problem
Another problem is if you’re drilling into something that is hard and soft so the tap that I was drilling into the tap was hard but the surrounding material was not so that could be a bit of a problem as well
I hope that this helps
Ray
Drill into broken studd at the sump af the engine
Now they make "multi-material" bits like this with slightly better geometry for cutting steel. Some manufacturers recommend high as possible rpm when drilling steel.
Yes, Bosch and a few other manufacturers make them they’ve come down quite a bit in price and there’s multiple sizes
I have made three videos on drilling, hard material or using the same technique just to show that from home with very little investment, you can drill harder material in a non-Ritchard set up
Thank you for taking the time to comment. It is much appreciated.
Ray
What rpm did you use?
i Just checked it was set at 600 but i should have changed it to around 400
Ray
my wife watched this with me. She said she needed to purchase that bit from you because I am hardheaded.
Would drop forged be considered hardened steel?
Honestly not really
But it does look good on video
This is a more honest representation of Drilling harden steel
czcams.com/video/rSShHH2Us5Q/video.html
can you tell how you get the high end diamond wheel for $5 on where of Facebook? thanks for sharing.
It was just luck
thats what got me hooked on market palce
What oil do you use?
honestly it was on sale when I picked it up for two dollars for 500 mL
ORAPI
Target top premium cutting fluid
I got it when My local Rona store was closing was clear out
You can use almost any type of oil
I hope this helps
Ray
What is the name of the wheel you used ? cheers
Wheel that I used is it American-made diamond wheel
I have a separate video on mounting it that goes into explain that I picked the wheel up for five dollars from somebody on Facebook marketplace and it had been on there for months. No one knew what it was.
Drop the price from eight dollars to five dollars who is selling off his father-in-law‘s woodworking tools
This particular wheat retails for around $500 but you can get them on Amazon much cheaper and for doing this type of work. A CBN wheel will work just as well.
Your demonstration is very informative.. I've yet to try it myself. Thank you. Oh, one question. Does it work with a smaller 1/8 drill bit?
Thank you for taking the time to comment
It should work with smaller drills now that I’m getting older I’m having a harder time dealing with this very small stuff
Magnification is required
@@shopandmath Thank you so much for your time and help. I've tried an 1/8" bit and it really worked.
For your information, I first used a high speed drill bit and then a cobolt bit. Both couldn't even scratch an 1/4" thick hardened steel.
I am glad to see that it worked out for you
and thank you for sharing
Ray
Try it sometimes with an old file. They are very hard. Useful information
there is a video of the same drill drilling out a HSS 1/4 -20 tap
For us lesser mortals, would you consider doing this demo with a hand drill (for those of us who are drill press-less).
I can do a demo what would you like me to drill threw ?
@@shopandmath I need to put some bolts through a spading fork head so that I can attach it to a handle. My HSS drill bits were worthless...including the one that broke in half.
@@tomterrific8574
spading fork head ?
can you send me a photo and some more info
shopandmath@gmail.com
is it the same as fork lift forks ?
@@shopandmath A "spading fork" is what is called a "garden fork" in some parts of the country. It is a four prong implement for breaking up soil for planting or light agricultural work where a tractor is overkill. Generally, it is like a spade (shovel) that tills the earth without digging a hole. The material is approximately one-half inch deep by three-quarters of an inch wide. My original tool came apart after way too much use. If you are in Canada, you will have to convert my English (American) measurement into Metric.
@@tomterrific8574 is it a available on amazon?
or is it as hard as a wrench ?
Be aware that when using carbide tooling on the mill or lathe you either do or do not use cutting fluid or coolant,the reason is this if you use oil/coolant(milk) you have to flood the part not just add it here and there because the carbide is so hard it cannot take heat stress ie sudden cooling ,it will shatter.
No lube or coolant can be done easily at reduced speed,in the case of the drill i would add the oil to the top of the drill shank to allow a constant feed down the drill as the oil gets closer to the carbide the steel shank will heat the oil up to match the carbide temperature,use a brush to add the oil as it holds oil on the bristles as a reservoir.
I've ruined plenty of cutting tools on the mill and lathe by not realising carbide is happy dry cutting,just don't thermally shock it or it's done for.
I wish i could find a $80 diamond wheel for $5. hahaha.
Believe me, you didn't need cutting oil.
You can also use a dremel type tool with cheap diamond wheels....About 50 cents per blade: czcams.com/video/bZUEs3FLhUo/video.html
the diamond wheel or a green aluminium oxide grinding wheel for carbide.
to be honest you need better camera skills for this video because it could be one of THE MOST IMPORTANT VIDEOS on youtube.
I thought that you needed a diamond wheel in order to be able to grind carbide masonry bits
I am doing the best that I can
there is a NEW how to drill harden steel video coming out Friday Oct 23 -20 at 9am
I have had multiple requests to drill very hard steel with a hand drill ?
i picked up a random chunk at work 59 RC
Ray
@@shopandmath please do it using a drill press cause it is more professional rather than a " the king of random" style video. This could really help people. sometimes you need to modify a hand tool for a specific function.
About the camera skills if you could use the help of an acquaintance of yours who knows about cameras and angles, he/she could really help you get the tip of the drill so focused when you zoom in.
Your videos are very informative and helpful especially this one
thank you
@@athrunzala5337
don't watch the next video this friday
I used 3 camras and there is a good amount of white washing
it was the last worm day of summer
and filmed outside
should have done it inside
Ray
A spanner isn't really hardened steel - it may be tough but not hard
I was intrigued until you said oopsie
"Masonry" only has one "a" not two. You repeatedly add an extra "a" between the "n" and the "r". Thanks for explaining how to sharpen an inexpensive carbide bit to drill hardened steel. Agree it would be easier to see with a larger bit. Maybe next time...
3/16" is 0.1875", not 0.875" as stated in the vid. Big difference. Just an oops, but not everyone will know that.
thank you for catching that
it was just a slip of the tung
Ray
hmm. home made swiss army knife with proper tools on it looks rather doable now
that is good to hear
Ray
May - son - re
Pet Peeve: it's may-son-ree, not mays-son-ary
I think in the last video I called them concrete bits
Nice video…this is nothing new…solid carbide bits are available at a price…I don’t understand why carbide tipped bits for cutting through steel are not manufactured as standard….probably because they’d last too long..lol
15 seconds in you say 3/16" is .875....3/16"is actually .1875
you are right thank you for showing me this error i will try to edit that part if i can
Ray
Great demonstration. By the way, the Egyptians built everything they ever built with copper tools, which proves the point, you can cut hard stuff with soft tools if you have enough time, are patient, and you put a good point on the tool. By the way, , you are guilty of a pronunciation that I used to be guilty of, until someone corrected me. The word is pronounced MASON RI not MASON ARY. There is no A in there. OK yell at me, but you will be a better person. Oh, and slaves didn't build the pyramids. Egyptian Patriots did. They were proud to work on such a big national project. It was also off season work and a way to make money when they couldn't farm. It was like their Moon Shot. With the pharoah buried in the pyramid, their future and security would be guaranteed. That's a bunch of information you didn't ask for. That could also explain their persistence working with dull tools. I used to be a teacher. Sorry! Video Liked!!
thanks, I;ve always said masonary, but no more :)
