You just showed me how to correctly sharpen drill bits! Never realized that there is a technique to properly get the drill square and sharp! Thanks so much for explaining this! I've struggled with this a long time, can't wait to try my hand at this now.
Decades of professionalism right here! All free, technically correct, machinest advice. Very grateful for what you've shared so thank you! I now know EXACTLY what needs to be done.
100% correct on that claim. I've now watched a load of drill sharpening videos on TH-cam and this is by far the best, particularly in the area of splitting the point (or thinning the web as Paul calls it). A lot of this has to do with the videography and the close ups accompanying the instruction, but also the simple idea of using a Sharpie to outline the area that is going to be relieved to show you what you are aiming for. Most people just show the webbing area being ground (often super quickly) and if you are lucky you get an out of focus view of the result.
Yes your are right, I love how patient he is when explaining the process. I’m working on how to do that my self. He is a great example of a humble craftsman. 🤜🏽
Best video I've seen on the subject. Clearly tons of experience. Solid filming and great detailed useful explanation. Wish TH-cam had more content like this! Thank you!!
Great to see that you are out of the hospital and back home again Paul! You and Mitch together have produced one of the best, most informative and entertaining TH-cam channels on bike and workshop subjects. Best wishes.
Ronald thank you for the update with Paul’s health. I’ve been checking the comments virtually daily. I’m curious, is there another area to look at for updates on Paul’s health?
This is the best drill bit sharpening video I’ve seen, many videos I’ve watched do not show you close ups of the angles, thank you for uploading this video it’s now in my saved list.
Good morning and hope you are doing better. I also sharpen drills by hand. You know when you're good at it when you're fellow mechanics ask you to sharpen theirs. Now retired, I have my neighbors asking to sharpen theirs. There is something meditative in the process and enjoyable. Blessings 🙏
Finally somebody on TH-cam that actually knows how to sharpen a drill bit. This guy is spot on the angle really doesn't matter what is important is to make sure that the leading edge is higher than the trailing edge and it will cut
Excellent instructions! I just now ordered a diamond wheel dresser from Amazon. $19.00. Thank you very much. Best drill bit sharpening demonstration and instructions out there. Instant LIKE and SUBSCRIBE! Greetings from Alaska.
Good to see you are replying to comments Paul, you will be back educating & entertaining us when you are ready, of that I am sure. Beaming lots of positive energy from the UK.🤞
I have binged watched every episode now twice. Nope, couldn’t find Mitch. Reading your responses gives me hope that things are going well and getting better. We are waiting for your triumphant return as I need a little inspiration to get back in my shop.
Not to give anything away, but the is a very small possibility you may be seeing a little more of Mitch in the days to come! Thanks for liking our videos. Mitch and I appreciate viewers like you 😉
Thank you both, that is the best "how to sharpen a drill bit " that I have come across. I have always known the basics but you have clearly and simply upgraded my skillset. I have subscribed. Thanks again
When I was 18 and went to work in my first machine shop, the owner asked if I could sharpen tool bits. Of course I said "Sure". He took out a drill bit, ground the end flat and said "Sharpen it". I did. Been doing it by hand ever since. Great video Paul!
The best drill sharpening video in the world, I did my fitting machining apprenticeship 30 years ago in Sydney and I was lucky enough to have an instructor who was very much like Paul. Made me a better man and good tradesman :)
I don't normally watch drill sharpening video's but this time I did. What you showed is pretty much exactly what I was taught in the mid 1970's, including using two nuts to get 120 degree angle which is often 'close enough'. It's pretty much forgotten about nowadays so good to see it mentioned (I've never used a drill guide either and I don't have the rests on bench grinder) I will add two things though, the first you've probably seen, someone who 'knows how to dress the wheel' then using diamond wrong and losing the actual diamond from the holder and the second is using a slip stone (India stone) to remove the edge when drilling brass (to get zero rake but still have clearance angle) Conventional grind often 'pulls' the drill into brass.
Sounds like we have the same sharpening style. I thought about adding brass and plexiglas drill sharpening techniques but then the video would be even longer... I am a little amazed that my Diamond on a Stick has lasted me 40+ years. Thanks for commenting.
It took me a lot of time to learn how to sharpen a bit by hand. I got tired of buying drill bits. I finally used new bits to learn the angle, then put them in a drill press to test them. Learn on big bits first and that will help you. I finally mastered the process.
👍 , , , my grandfather was a machinist , , , started out during world war two , , , became a machine shop teacher here in Sault Ste Marie , Ontario in Canada at the Sault College , , , i took machine shop all through high school and at the college , , , i really like watching your channel and the things you show and teach , reminds me all the stuff i learned and the the things my grandfather showed me. 👍
Hey Paul, I learned to hand sharpen bits in high school, a skill that is still with me to this day. A story to go with that skill: I was supervising the construction of an observatory. The crew assembling the steel frame for the dome was drilling bolt holes to secure the dome. They told me they had to stop for the day because all their 1/2” bits were to dull to continue. I asked if they had a hand grinder, they did. I clamped the grinder to a beam and quickly sharpened 6 bits. They where stunned that it A- could be done at all, and B- could be done using a hand grinder, C- that as a project manager I knew how to do something they didn’t … Cheers.
This was one of many skills I was taught in Jr. High shop class in the 70s. It seemed easy then but now when I try to free hand a drill its a challenge. Its great to see someone with skills!
Really clear, informative and detailed explanation of the subject. I've recently discovered your channel and as a long time mountain biker and a woodworker I absolutely love it! Especially your chilled method of teaching, I know a pro when I see one. I picked up a few good techniques here, usually I put a sort of micro bevel then the rake angle on my bits which works ok but I can't wait to try out your more fluid motion. Thank you Paul!
Thank you for the information on how to sharpen a drill bit. I never knew how to do it ,but now I'll be able to save some of the ones that got messed up after using them.
Whew, this is just as frustrating as learning to sharpen knives on diamond stones! I finally was able to get in bit to cut, I have have over a hundred to sharpen, I appreciate your time!
Took me back over 40 years to being an apprentice in the machine shop and being shown how to sharpen drill bits. And truing the wheels. Thanks for the memory Paul.
Excellent. I have struggled with this for years. I bought drill sharpener electric things and they never worked or I was using them wrong. This is the most comprehensive, clear, concise explanation I have ever seen. I have bought numerous bits just because the old ones were dull. Thank you!
Another very good instructional, anyone can read a book telling you what the correct words are, but a simple explanation and a good result are often the best teachers. Thanks guys.
Thank you for the helpful tips about the web! I've been having trouble with that, myself. I've gotten a lot of my bits razor sharp, but end up with a thick web and I've tried various methods to thin it down, but I never thought of just doing the wee corners like that. I'll give that a try soon!
i can just listen to you all day you made me feel so relaxed. the world needs more people like you. thank you very much Paul. your a legend with the gift of the gab. i am now subscribed and will watch all your other videos at my earliest convenience.
Thanks, just learning this and your video is brilliant. You clearly have a huge amount of experience, it is a pleasure watching you work. I have a lot of practice ahead of me!
Very helpful for someone who never seems to get this quite right! I think I need a knew wheel, and something to dress it with. And then some practice. Your photography is great, you get right in there so we can see what is actually going on. Thank you.
good video !!that's the way I was leaned to do sharpening drills 50 years ago , by my stepfather who was a professional tool maker, now my viewwing is not very good , can't sharpen smaller drills than 1/8 " on one shot...but manage after redoing from flat and cheking after each step , still have the diamond sharpener ( only good tool for dressing the weels )
Mr Brodie.Your years of experience shine through.This video was an absolute pleasure to watch and understand.Keep up the amazing work..Thank you,from Ireland.
Thank you Paul and Mitch, that is the very best drill sharpening video I've seen, nobody has any excuse now for throwing away dull/damaged drill bits.Also, really appreciated the extra detail on dressing the wheel too.
ii dont need to sharpen drill bits. I'm watching to get functional storage insprations. Nonetheless, i did learn a thing or 2 about sharpening so thankyou, sir. You have my sub 👍🏼 "Learn from yesterday, live for today, hope for tomorrow. "
Hi Paul, Thanks so much for your entertaining and educational channel. We all hope you can overcome your injuries soon. Early in my Electrical Trade apprenticeship 50 years ago I was taught exactly what you have shown in this video. I have sharpened all my own drills and everyone else's ever since and is a great skill to have under your belt. Greetings from Australia.
Thanks for this great instructional video on drill sharpening Paul, a very detailed explanation and you went over the tech side of it very clearly. I found what you were saying to be very easy to follow with plenty of close up views. It's easy to wreck a good drill, (and I've wrecked quite a few) if you don't take care and know what you are doing. I saved this video for future reference. First thing tho', I'm gonna check out my grinding wheel - Thanks Paul.
The best but video and very cool to see old school simple tips with simple rules to follow. People always trying to use a device to sharpen bits but it's not a tool..... it's understanding what needs to happen while sharpening. Thank you so very much...... now I just need to practice my knowledge just learned.
Nice one Paul, the diamond tipped dresser is great, taken from dressing tool and cutter or surface grinding wheels. Your just like myself, softer material to cut more acute angle harder more obtuse, I always just eyeball a good drill for the general angle. In terms of thining the web, we always done it as the drill length gets smaller as the web thickness increases for drill strength, so as you grind the drill down the top land increases, hence thining the web. A great tip for checking each cutting edge of the drill is at the right height is to screw a piece of soft metal against a wall, then a V piece of wood or metal at right angles to. This allows you to place your drill into the v block and rotate and scratch on the soft metal when both cutting faces scratch and follow the same lines as you rotate, then voila each cutting face is cutting at the same height Thanks again
Hahaha! Thanks for adding the 🦚 'Peter Counter' Mitch! 😂 And thank you Paul for sharing your sharpening know-how! Great video! Hope you feel better soon.
Combining your expert knowledge with a flawless video makes a fabulous teaching tool. Paul, you are an exceptional teacher. Thank you, and keep up these amazing tutorials.
I was a machinist at an aerospace company when I was tasked with sharpening drills for about 6 months. Drilling titanium and stainless needs a good sharp drill! We had so many drills we had to send them out to get sorted. During that time I developed "The Eye". I still use a drill gauge though to check flute length and angle so that the hole will be sure to drill on size. Pedestal grinders in a shop with many machinists, mechanics, and passersby meant the wheels always had rounded corners. That made thinning the web after hand sharpening a problem. By mounting a thin cutoff blade on the opposite end of the grinder, I was able to make a nice sharp "split-point" with a wheel that wouldn't get rounded corners.
When I have to drill say 1/2" holes by hand, I have found impact drill bits work amazing on steel, and no worry about the drill ripping your arm off when it catches near the end. It just doesn't catch using impact drill. Goes like butter, except when I had to drill through an area adjacent where I welded. That was no longer mild steel and it really dulled my drill bit. I have sharpened my own before on a grinder but your explanation was clear with the how and the why so I learned something and will do a better job with my impact bit - hopefully the geometry is similar. Many thanks!!!
LOL! You guys did the Peter counter!!!!😅 Get well soon Mr. Paul, take your time to heal. And thank you and Mitch for the nicests videos on YT! Good vibes from a fellow motorcycle builder from Brazil.
Hi Paul & Mitch, Great demo and explanation on the drill bit sharpening. My college machine shop teacher didn't explain it anywhere near that well! Thanks again!
Another amazingly well filmed and documented teaching video, thank you, Gentlemen. Missing seeing you guys on TH-cam, hope you are recovering well Paul.
Thank you Shane! It was not easy showing how to sharpen a simple drill bit. I am slowly getting better, and we hope to resume filming possibly in a few months time 😉
One thing that wasn't discussed in this video is head on bit geometry. When you look at a twist drill bit head on the chisel point ( that's the bit in the middle the web) will have an angle in relation to the cutting lip angle. There's two cutting lips one on each flute and they both have to be parallel to one and another. Go look at a bit. If it's sharpened right those cutting lips are parallel. When they're not even they're not parallel. That's not good. You need to keep grinding until they are parallel. Otherwise you'll drill oversized holes. The bigger of the two flutes will swing wide. Throwing two chips is a sign you have an evenly ground bit. If they're not even one lip will cut and one won't. A large part of learning how to sharpen twist drills is studying the geometry. Which in practical terms means really looking at a drill bit and seeing why it cuts. If you make the bits you sharpen look right they'll work right. Paul covered heel relief but he didn't cover parallel edges. A twist drill are chisels in the round. That's how they work.
That's true. However, when you keep track of cutting lip length and angle - because of it being a twist drill - you will be pretty darn close. You develop the feel and chip formation can be checked visibly. Going one step further, you can put a micrometer on the mill table and check the height of each individual flute. An experienced machinist will keep a tolerance of 0,05 mm, but this will of course grow the more you sharpen the same drill.
When hand sharpening achieving perfection is all but impossible , we can get close but if you want it perfect use a tool and cutter or D bit grinder , i prefer 4 facet sharpening on anything over 10mm 0r 3/8 inch and anything under is either hand sharpened or replaced . I have yet to find anyone on TH-cam that shows how to sharpen a number 80 drill !
@@ianbertenshaw4350 Sharpening is not the same as grinding a drill bit sharp from blank as Paul here does. You can dress the edge and here's where the 0,05mm comes into play.

Your just like myself, softer material to cut more acute angle harder more obtuse, I always just eyeball a good drill for the general angle.
In terms of thining the web, we always done it as the drill length gets smaller as the web thickness increases for drill strength, so as you grind the drill down the top land increases, hence thining the web.
A great tip for checking each cutting edge of the drill is at the right height is to screw a piece of soft metal against a wall, then a V piece of wood or metal at right angles to. This allows you to place your drill into the v block and rotate and scratch on the soft metal when both cutting faces scratch and follow the same lines as you rotate, then voila each cutting face is cutting at the same height
Thanks again
Steven, thanks for watching and commenting 😉
Hahaha! Thanks for adding the 🦚 'Peter Counter' Mitch! 😂 And thank you Paul for sharing your sharpening know-how! Great video! Hope you feel better soon.
Thank you.
thank you for taking the time to really explainthr bit . good job sir i understand everything you explained.
Thank you Stosh!
Paul, give Mitch a raise, that was outstanding camera work.
Yes, I thought so too!
Combining your expert knowledge with a flawless video makes a fabulous teaching tool. Paul, you are an exceptional teacher. Thank you, and keep up these amazing tutorials.
This is an excellent tutorial covering points that all the others ignore.
Hope you get feeling better man. Take it easy and heal up 🤙🏻 miss seeing the videos but praying for a quick recovery for you.
Working on it for sure!
I was a machinist at an aerospace company when I was tasked with sharpening drills for about 6 months. Drilling titanium and stainless needs a good sharp drill! We had so many drills we had to send them out to get sorted. During that time I developed "The Eye". I still use a drill gauge though to check flute length and angle so that the hole will be sure to drill on size. Pedestal grinders in a shop with many machinists, mechanics, and passersby meant the wheels always had rounded corners. That made thinning the web after hand sharpening a problem. By mounting a thin cutoff blade on the opposite end of the grinder, I was able to make a nice sharp "split-point" with a wheel that wouldn't get rounded corners.
That sounds like a good solution. Thanks for commenting.
Wonderful video Paul, best wishes from Florida, Paul.....
Thanks Paul, appreciate your comments...
Best drill sharpening video I've seen. Now I think I can actually do this! Thanks!!
Glad I could help! Thanks for watching.
Awesome instruction.
Thank you Tyler....
this is great , the camera work and explenation was very well done . thanks so much
You know it's right when you see swarf coming from both sides of the drill as it goes in. :)
When I have to drill say 1/2" holes by hand, I have found impact drill bits work amazing on steel, and no worry about the drill ripping your arm off when it catches near the end. It just doesn't catch using impact drill. Goes like butter, except when I had to drill through an area adjacent where I welded. That was no longer mild steel and it really dulled my drill bit. I have sharpened my own before on a grinder but your explanation was clear with the how and the why so I learned something and will do a better job with my impact bit - hopefully the geometry is similar. Many thanks!!!
Thanks for watching.
Good Morning you two. Thanks for the tip!
The world is on pause, waiting for You.
We are expecting You to come back stronger, better and with a good fit. 💜
Thank you Jim. I will do my best. Paul 😉
LOL! You guys did the Peter counter!!!!😅 Get well soon Mr. Paul, take your time to heal. And thank you and Mitch for the nicests videos on YT! Good vibes from a fellow motorcycle builder from Brazil.
Yes, the Peter counter! Best wishes to Brazil.
@@paulbrodie Thank You Sir!!! Your work has been a major inspiration to me. Hope you get better soon!
@@akemisaita8824 Thank you Akemi 😉
Nicely done
Thank you very much....
Your sharpened drill sounds nice as it goes thru the piece of aluminum.
Thank you for sharing.
Hi Paul & Mitch,
Great demo and explanation on the drill bit sharpening. My college machine shop teacher didn't explain it anywhere near that well! Thanks again!
Thank you Tom.
Another amazingly well filmed and documented teaching video, thank you, Gentlemen. Missing seeing you guys on TH-cam, hope you are recovering well Paul.
Thank you Shane! It was not easy showing how to sharpen a simple drill bit. I am slowly getting better, and we hope to resume filming possibly in a few months time 😉

One thing that wasn't discussed in this video is head on bit geometry. When you look at a twist drill bit head on the chisel point ( that's the bit in the middle the web) will have an angle in relation to the cutting lip angle. There's two cutting lips one on each flute and they both have to be parallel to one and another. Go look at a bit. If it's sharpened right those cutting lips are parallel. When they're not even they're not parallel. That's not good. You need to keep grinding until they are parallel. Otherwise you'll drill oversized holes. The bigger of the two flutes will swing wide. Throwing two chips is a sign you have an evenly ground bit. If they're not even one lip will cut and one won't. A large part of learning how to sharpen twist drills is studying the geometry. Which in practical terms means really looking at a drill bit and seeing why it cuts. If you make the bits you sharpen look right they'll work right. Paul covered heel relief but he didn't cover parallel edges. A twist drill are chisels in the round. That's how they work.
That's true. However, when you keep track of cutting lip length and angle - because of it being a twist drill - you will be pretty darn close. You develop the feel and chip formation can be checked visibly.
Going one step further, you can put a micrometer on the mill table and check the height of each individual flute. An experienced machinist will keep a tolerance of 0,05 mm, but this will of course grow the more you sharpen the same drill.

if you can hand grind a drill to within two thousandths of an inch ( approx 0.05mm) you are a god😂
When hand sharpening achieving perfection is all but impossible , we can get close but if you want it perfect use a tool and cutter or D bit grinder , i prefer 4 facet sharpening on anything over 10mm 0r 3/8 inch and anything under is either hand sharpened or replaced . I have yet to find anyone on TH-cam that shows how to sharpen a number 80 drill !
@@ianbertenshaw4350 Sharpening is not the same as grinding a drill bit sharp from blank as Paul here does. You can dress the edge and here's where the 0,05mm comes into play.
"chisels in the round" ... I'll remember that.
What a wonderful piece of knowledge showed precisely , with calm and serenity, best teacher imposible. Cheers from Brazil Paul.
Great tutorial on drill sharpening, 👍, the best I have seen on TH-cam, thanks.
Nice comment, thank you.
Thanks Paul and Mitch love the attention to detail and what you share with us. Go well.
