This is The Ultimate Guide To Drill Bits. Putting HSS (High Speed Steel), Cobalt, Carbide tipped and solid Carbide drill bits to the test. Yes It's long but Compared to the Year + it took to gather the information it's not that bad. So Sit Back and learn or keep wasting your money on junk, trash bits that keep breaking and not drilling through what you want them to.
RHC - Rockwell Hardness C
HSS Drill Bits - Work well up to the 50ish RHC
Drill - Mild steel, Some tool steel, Some Spring Steel
No Drill - Hard Plate, Anti Drill Plate, 404c Stainless Steel
Pro - Good in Hand Drills and most drilling applications
Con - Has limitations in hardened steels
Cobalt - Works up to 58ish RHC
Drill - Mild Steel, Some Spring Steel, Some Tool Steel
No Drill - Hard Plate, Anti Drill Plate, 440C Stainless Steel
Pro - Good for hand drills and most drilling applications
Con - Has limits with hardened steel
Carbide Tipped - Will drill almost any steel, Hard, Stainless or Mild.
Pro - Drills all steel
Con- Blunt tip requires extreme pressure to produce cuttings. Drill bit is hard to start on all steels.
Diamond Coated Drill Bit - Cuts on most steels(Not Hard Plate) just not for long.
Pro - Will Drill most steels (Not Hard Plate)
Con - Cutting stops quickly after diamond grit has warn off, Then behaves like HSS bit
Solid Carbide Drill Bit - Cuts all steels.
Pro - Sharpened points wont "walk" like carbide tipped bit. Cuts all steel
Con - Sharp tip and fine edges can chip easily and ruin drill bit. Not for hand drills. Expensive!

Wayne your journey to unravel the chaos and enigma of drill bits to metal was an excellent practical scientific approach at shinning a light of clarity to the appropriate application of each type of drill bit metal versus the types of samples. Excellent job regardless of the when your instructional video was done. A true timeless classic. Good job.
Machining 101 is workholding. 101.1 is center punching. Diamond and carbide bits need to be run fast. Instead of websites, try the Machinery's Handbook.
What an enlightening and thorough review of drill bits. Nobody seems to know all this info you have touched upon. I see all these people drilling lug studs and some succeed and some dont but they dont even know what metal their drill bit is made of. Thanks for your explanation! Great job!
Thanks Wayne , after all of these years I finally know what drill bits to buy , super good informational video.
Nicely demonstrated
one of the best demonstration UA-cam could have for drill bits .thanks
Thx for watching!
Thx for watching!
I appreciate you doing this Wayne.Good job

carbide is carbide, Tungsten carbide is the same as any other carbide mentioned in this video. It's all the same
Excellent topic, what is your opinion about hi-moly drills?
look up the ultimate guide to drill bits here on YT. There great for hand drills as they are more forgiving
For heavy used for automotive mechanics daily garage broken bolts there are these various automotive grades that I have tried and all failed I really appreciate your video just really curios for hand held drills the bits for automotive, really now I understand a little better
Very good information for the basic machine shop person like me. I am sure there is a lot more to this type of work (like drill speeds), but your video (and your research) just took years off my research!
You can use a diamond 4" thin smooth wheel to sharpen carbide bits and lathe bits. I got mine from harbor Freight for cutting masonry. Just mount it on jour bench grinder next to the stone wheel and it works for me.
I have a mechanic background so its very good to know. Excellent job!
excellent video thanks for the info ,muchly appreciated ,keep up the good work Wayne
Wow! That was a great demonstration. I now have a much better understanding of drill bits and hardness of metals. Than you.
Thanks, good video. I was looking for a bit to drill a hole through the front wheel axil of my lawn mower because the horseshoe clip kept coming off. Now I know what I am looking for.
Thank you. I'm having a problem with drilling through hardened steel for a project and this will hopefully help.
knowledge is power, thank you..
I enjoyed watching your informative video. My recent challenge is to drill out bolts from the exhaust manifold of a 350 GMC V8. What a nightmare. I wrecked a bunch of bits. I used slow, medium and high-speed attempts. Bottom-line is that your video made me appreciate the materials science behind various steel and their respective hardness. Nice job and thanks again!
Well you learn something new watching excellent videos like this good on you for doing this it's blokes like yaself that put the hard yards in that help and learn save thanks keeping coming
Np
I figured this out decades ago when I tried to drill a hole in a digital caliper. Worked like magic.
You know, I used to have an engineer friend that I thought was probably one of the smartest men I’d ever known. I mean you ask him a question and he didn’t just spout something at you, like most no it all’s. He thought and then spoke and he made sense. He could figure stuff out...but you know the greatest lesson that I ever learned from him? One day we were talking about something and he looked over at me (we were riding down the road) , and said something I have never forgot. He said, “you know, I learn things from you every day”. Well I thought, damn.
Lesson learned, you’re never too damn smart that you can’t learn from anyone else!
This was the Randomest post ever
@funnyman1972 Sounds like someone else has had that same experience in the past in a different land!
Bet you were the friend that he learned what the fuck not to do ....for sure you taught him alot
@@ynotitsfun990 Seems you get your jollies putting other folks down. The point that started this whole topic was "we can all learn from each other". What I learned from you is some people are
just really good at being jerks.
YNOT!! itsFUN you are a foolish person, stop trolling good, productive folks!
Thank you for video,great video and you just help me with sailboat project drilling ss
Very helpful thank you so much for your video!!! Hi from Ecuador 🇪🇨
Great video Wayne!
Interesting test. Thank you for the research. I am trying carbide in a hand drill and had some luck.
Very helpful. thank you.
Good video thanks for your research!
Thank you! Upon fixing a car for a loved one, I learned very quickly that all drill bits are not created the same! The only bits that I found locally, within a store was cobalt bits unless I could properly sharpen carbide tipped masonry bits so, I chose Irwin cobalt bits. My 20 some mile away/ local Royal King sold both single's & sets of Irwin cobalt drill bits & just the other day, I went to purchase more of them to add to my collection, I advance of a much needed repair (drilling seized suspension bolts holding on my rear coil springs housed by it's own control arm & also the rear shocks-mounted separately but, all corresponding bolts will need cut out & drilled & replaced, I am assuming because, I know the shock bolts are seized!) In wanting to ensure that I have everything I need, My local Royal King has always had the Irwin cobalt bits that I have needed until now!!!! When investigating drill bit's & what to purchase, It is confusing! You should sharpen those carbide masonry bits for best effectiveness!!!! I will be subscribing & re-watching at such a time when I haven't been up all night working!
I LOVE YOUR VIDEO. SPECIALLY THE SCIENTIFIC APPROACH. I WILL STUDY IT SEVERAL TIMES. I SPENT SOME 6 TITANIUM BITS FROM LOEW'S TRYING TO BORE A TINY HOLE IN A PIECE OF STEEL TODAY. TOMORROW, I'M GETTING A CARBIDE BIT. I HOPE THEY HAVE ONE THAT SIZE. THANKS.
Thank you for your testing and sacrificing tools - it really helped me to select the right bits for my stainless sheet metal needs.
Great thx!
Thanks Wayne,
Great video.
very intresting, could you do a video on the different types of cutting pastes
Carbide tipped bit that are designed to drill glass and tile have worked well for me drilling hard steel. They are cheap and have more of a cutting edge over masonry bits that are designed to be used in a hammer drill.
Good research and work Wayne! Really informative.
Thanks for sharing!
Learnt a lot - for my needs i think i need to get the solid cobalt bits
Great video thanks for uploading.
Very informative. Well done.
For what i used to in my work and now in my home shop, I use cobalt bits. Never been disappointed. I do have std hss bits also and use those on other stuff that softer than hard steel. The sets I have are not your normal big box store sets.
Glad to help out.
Nice slow detailed summary
AWESOME VIDEO ! MORE IMPORTANT THE INFO YOUR SHARING . THANKS A BUNCH ! Now I can drill this bolt out of my engine , I hope.
you most certainly can if you choose the right bit!
Great video thanks for sharing
Vete useful. Thanks for effort
Thanks for the great vid. I been using carbide bits with just a spot of oil to drill my 1095 knife blanks before the heat treating process and having some success. But I've noticed I go through quite a few drill bits every couple of months. I'm gonna try the kobalt bits and see if they last longer and drill better. Looking for a good source for metric bits. Any ideas??
Thank you for the video. Before I watched it, I didn't know to use heavy duty grease, and I melted a titanium and cobalt bits. I'm using titanium a bit slower now, but I have found cobalt to be better, as you have demonstrated. Thanks.
+William Pittenger good to here. TTP- Cut It paste works best as well ua-cam.com/video/NdPM1lCDYFI/v-deo.html
that was a serious demonstration. cheers
+David Magazzi THX!
Verrrrrry informative thanks
one word.......OUTSTANDING
+Dennis Arterburn Thanks!
Thank you so much!!
thx for the upload Mr. Winton
thx for watching!
Very informative thanks
NP!
Thanks!
Thank you sir
Very informative.....a buddy of mine is a machinist and makes bits....says you can sharpen carbide masonry bits with a grinder and make them cut metal better
Hi Wayne,
Excellent video, quite a tutorial about drilling! Thanks for sharing...How about drilling (1/4" hole) a grade 8 bolt deep enough to use an "easy out" extractor on an outboard? These four bolts fastening the lower unit are seized to death and need to be drilled and removed. Only hand drill can be used though...Tried an HSS and a rather cheap cobalt bit but only pilot depth holes before they got dull...Thanks a lot for your time.
Thanks 👍
i noticed the same thing on my drill press as yours. The table dips as you bring down the quill. in turn the drill bends to the front. what I did was to use a old floor jack to study the drill table from dipping down and well la, the bits drill straight. The bits I use is titanium and work well with the table solidly reinforced..
This guy is great
thanks for the info and the great vid....
NP
Sure am glad I got a pure tungsten carbide bit... Very interesting and detailed video, tungsten carbide ain't nothing to fuck with :P
Try mount your workpiece on a vice to begin with instead of holding it with a vice grip.. The initial contact of cutting edge wil chatter and dull your cutting edge from the beginning if not securely mounted. also understanding feeds and speeds will help.
thank you drill chuck norris. what would we do without you.
How dare you bring your common sense into this equation.
I have a severely retarded brother who chucks up all of his hss bits with his front teeth.
OH wait, you answered my questions at min. 45 I think.
Hello from Montreal Canada 🇨🇦 I’m a new subscriber love your channel learning plenty from ya. I have a question which drill bit or a good drill bit can I use for a 1/4 to half inch brass to drill holes 🕳 a drill bit that can go through Brass like butter or with ease ? Thanks for sharing your videos yr a tremendous help to me thank you ?😃❤️👊🇨🇦 oh just to mention I use only cordless 20v DeWalt tools 🧰
Good vídeo thanks
Hi, Would you recommend using a Cobalt M42 bit for drilling a tiny 3mm hole through a electric motors hardened steel output shaft?
I need to hand drill a 4.5" hole on a SS plate that is 1/16" thick. What do you think is the best way/bit to do that? I searched but don't see a 4.5" bit.
GOOD INFO
Excellent video, I know it’s basically a comparison test, but there are so many other considerations to take into account. Drill speed, tip angles etc. Also when using a single bit on all the materials it will become less sharp at each stage….It’s pretty much common sense that the hardest material..carbide, came out on top. But then your also dealing with financial considerations…Carbide bits can cost more than than the object you intend drilling..
This one was as good as the other was bad! You learn fast, keep on going, young man! Thank you!
Perhaps you could try sharpening the masonry bit?
Man! What a wonderful video. thank you ever so much for all the time, $$ and effort you put into this. Saved thousands of people so much time and money. I was told that carbide was too brittle for a drill press. Did you find this??
Nope. you just need to be careful
hello friend i know burning a hole isnt exactly drilling a hole but i have a oxyhydrogen torch that i use to drill holes threw stainless steel with , up to 3 mm thick. the needle like high pressure flame can punch threw 1.5mm SS in just under a second.
it is realy good for drill SS tubing without a drill press
Looks like you have it figured out.
what would be the best drill bits to drill a hole through .15 inch titanium? I've heard carbide is the best for titanium. what drill bits and what types?
very interesting Wayne!
thx!
Uk gas bottles what drill bits are good to use on them.
So witch is the best in your opinion im doing alot of drilling and looking to buy ASAP witch should I buy I will be drilling all types of metal
Can you anneal stainless steel with a map/oxy torch before drilling it?
Hi Wayne from Adrian in the UK. I am about to start my own locksmith business hence the research for the best drill bit and this video confirms what I thought that Sharp! Tungsten Carbide will do most drilling you need.
But as a Ford trained toolmaker just thought I would add a little info that might help some viewers.
1/ When you drill steel, (any steel) if the drill is blunt the metal will work harden as you try to push it through making the metal harder in the process. (even mild steel will work harden under a blunt drill)
2/ If you can, it is better to have a constant supply of coolant to stop this process of work hardening, happening. Soluable oil - (DROMBUS OIL) is best but liquids work better than grease)
3/ The masonry bits can be sharpened on a small cheap tool grinder if you buy the right wheel for it. (Usually a green wheel is right for t/carbide) BUT CHECK BEFORE YOU BUY.
4/ Always keep the drill bit sharp, even the best bits lose there edge quickly so it can be necessary to sharpen it, to complete a hole depending on how deep the hole is , ie. how thick the material is your trying to drill.
Good video though saved me a lot of research :-)
Thanks again , I will use your recommendation !
What will be the best drill bit to drill broken end head bolts on engines in order to use
easy outs to remove them.
Also who makes good solid carbide samall bit sets. Thanks for your advise.
Thanks for the sharing this excellent video.
Look up my video called " how to drill out a broken bolt, drillbit and tap" by wayne winton here on UA-cam
HSS seems to just be a category which makes a lot of sense
Can you reharden your drill bits to make them harder. There will be less flex but heck even medium carbon steel can get pretty damn hard.
Great effort Wayne. Lots of good info.
thx!
Wayne, thanks a ton for this video. Very informative. Do you remember the drill speed you used while filming this? Is there any relevant experience you can add regarding speed, performance and durability with various bits?
+Ben Griswold Slower is always better. This is set on the slowest setting. Speed creats heat, heat causes failure
Ya that's what I've been taught and practice. Reason for asking is I've heard some conflicting information; more specifically that carbide bits cut better at faster speeds because they can hold up to the heat. Not sure I want to experiment testing this theory if others already have.
Insanely good video. Thank you so much!
Wow, like, how 'bout a vise for your scrap and a jig for the bolt??
great video man. just great
thx
+Wayne Winton I drilled to small hole through a 8mm Allen key last night then threaded them. I used dealt bits in the yellow box. they actually cut through it. Very interesting. what do you think of that??
thx
Thx
Good vid!
Thx
I decided to by cobalt since it's for home n mechanic use n pocket friendly. I have been buying drill set that keep on breaking n becoming blunt.
It's also worth the investment of a drill dr. bit sharpener if you use them often.
Great educational tutorial. I commend you for your time, research, & thought that was put into this video! Extremely helpful & interesting.
Thank you for your knowledge and time! Keep it up!
I'm having a real rough job trying to drill a few small holes (less than quarter inch) through one of the steel beams in my basement.
It looks just like your typical steel structural beams, but maybe because the house is 15 years old and has gone through multiple heat cycles this stuff has turned into something from an asteroid.
Now before you all yap that I shouldn't be drilling through this beam, I'm literally making a couple of less than quarter inch holes that you would barely see next to the size of the beam.
It's half inch thick the area that I'm trying to drill into.
I have a new dewalt 18A cordless drill with adjustable speed and hammer drill functionality.
I also have an older plug in to the wall seriously heavy duty hammer drill (the type with big support handle for leverage) and I've tried Bosch carbide tipped, Cobalt (multiple brands) and this steel literally laughs in the face of everything that I can throw at it.
I'm at a total loss and hope for some advice as the guys at home depot are just wasting my money and I'm tired of wasting gas and cash on drill bits that are dead within a minute and barely make more than a small dent in the beam.
I use cutting paste.
Appreciate any advice.
Look on ebay for screw machine length drills AKA stub drills. Buy either M35 or M41 (not M42 with a hand drill). Apply a lot of pressure while drilling on the drill's slowest speed. Good luck.
have you ever tryed cryo bits?
For anyone wondering what the $300 bits are called or who they’re made by, they’re made by Viper. I use the exact same ones in my shop at work and I can attest to the quality of the bits and the lifetime warranty. If you brake one, send it to em and they send you a new one. No questions asked. Very very very good company. If you get the chance to buy a set 100% worth it
diamond coated dremel disk cut ceramic tiles and also sharpen wood chisel beautifully. Masonry bits are fairly cheap . if they can be sharpen with a diamond coated dremel disk
one can cut the hardest steel at a low cost without the wobbling
Boy that diamond bit made a nice little dent on that hardened plate steel, to bad the bit was already beaten up from previous drilling, would of loved to see it new and not giving up so fast.
I thought there was supposed to be water suspended in the grease to prevent work-hardening and to drill with smaller diameter first on less brittle hard steels???
Also diamond is carbon which is soluble in steel (like high carbon steel lol) so using it to drill steel seems really strange
I watched the entire video. Thanks for making it. It answered a number of questions that I had and I couldn't solve by research online. Two Thumbs Up!
Lol o geeze. It was like nascar, i was waiting for something exciting to happen. Theres some information here for the layperson, but for people that do this on a regular basis theres nothing new here. Quick tip, as soon a drill bit stops being able to cut a material, it almost always has had the cutting edge ruined and will need to be sharpened. Even import basic hss drills as long as they come from a real industrial supplier are usually pretty good for most things. Ill pilot most materials with a high cobalt content split point drill, as they are tougher and need to chisel. Even fairly tough and hard materials can be drilled with standard hss easily as long as they have a pilot because they dont need to "cold chisel" the clearance for the web which is what takes the most energy to make a hole.
Sharpen your masonry bit like a normal bit and you can drill hard steel I have drilled oil holes in outer bearing races and broken easy outs out with them , now you can buy solid carbide drills
dunstrugglin I watched a John Heisz video yesterday where he did this with varying success. If I remember rightly on the occasion he failed he put it down to his own drill sharpening technique.
