Sharpening Drill Bits - The Long Way Round

good vid

In my country we don’t sharpen drill bits we replace not worth time and energy..

I could tell you why you're not starting with square stock, but I'm afraid to broach the topic...

There is one thing this video fails to mention. Don't try this left handed. You can not sharpen a drill left handed. I know. 50 years of sharpening drills by hand and even though I am left handed I never got the hang of sharpening drills left handed. I never use a fixture,it's easier free hand. When sharpening a drill it does matter what material you are drilling. Brass and plastic like dull drills or drills with a negative edge. One last tip. If you really want to learn how to sharpen a drill bit you will need drills. Go to a flea market and find some one selling old tools and get yourself some dull drills . Find a good(as in not cheap) grinder sit done and go to it until you got it.That how the old German bastard had me learn.

is it because the round piece of material doesn't have any edges that need to be cut to a cylindrical form?

Wow man great info and entertaining! Thanks

Excellent Tony that was best video for sharpening that I have seen 🙏🏼👌

Love your humility. Made it very enjoyable to watch.

I can't remember how many times watch this video, this is gold

Thank -you The Best Video on the subject I Have Ever Seen . And With 2.2 M VIEWS Aparently a Few Others Agree .

Wow 2 million people watched this. I can't hardly believe there are 2 million people that wanted to learn something. Thanks for the knowledge tot.

Man love your videos, you are an amazing teacher

I love your videos. Greetings from Europe, Estonia

The wrong way? 😛🤣

I'll give ya 2 thumbs up gradpaw.

Ok now something my uncle taught me, to give the bit a center point, after your second grind on the tralling side up to the web almost touching the cutting edge on the sharp 90 dgr corner of your wheel cut a slight kerf in to the web at to make a sharper point. Shhh its a family secret
This will keep the drill tip from wondering off your center punch mark it also helps the tip dig into the metal faster works good on a split point drill bit you've made
My uncle started do this in the 1950s.

Actually you can cut a helix on your milling machine, if you had an indexer.
Just thought you should know.
Hey I thought this was sharpening by hand. I dont own a Bridgeport. Not that I wouldn't want one.

Ok to be fair this might work better on a 5 axis cnc mill lathe. But you dont have that either. Back to you said hand sharpen now your showing off a lathe .

Cease to struggle and you cease to live.

what if i don't have a pair of nuts?

Amazing video. I learned so much. Thank you!!

Awesome video highlighting a amazing innovative service doing good

I think you need to do a collaboration with thecrafsman

I learned to sharpen drill bits as a teen in the 80ies, with no instructions, I had to because I couldn't afford to buy new ones.. I wish i could have seen this back then, then I would have understood how it's supposed to work, instead of just trying trying trying and finally have something that (sort of) worked.

I really enjoy these ten minute videos 🙃

Drills for brass have a slow helix, the opposite of what was said....... Is there a flaw in what the infallible ToT says 🤔😆
Nah, I can't believe it, this man knows all 🤙😆

The smiley faces made me subscribe

"I'll bet that thing looks huge in the camera as compared to what I'm seeing" t.o.t.

I know how to sharpen drill bits and I still enjoyed that, I also found out why I do various things so thanks for that as well.
Cheers dude thanks for sharing

Brill video

Every day is a school day 💚🇬🇧🌱

I do think im on the same page

Well after adding the flute angle i do think its now a twist drill the drugs are now kicked in

i think this is more of a spade drill Its early in the morning The drugs haven't kicked co0mpletely in

Thanks drill bit mastery.

That angle is not fast, and it is not slow. It is half-fast... ;)

It was I'm looking for! Thanks so much!

I've been a machinist for 40 years and 38 of em with sight in my right eye only due to a hunting accident, but anyways sir, your explanatory video of drill sharpening (in my opinion) is textbook perfect and me watching someone do something correctly (as you done), it'll help me with grinding my clearances, I have no depth perception whatsoever. You have been very helpful. I'm gonna see that some of my friends watch your video. Thanks for sharing.

Your half and hour was worth every minutes.

Large drills are easy to re sharpen would be more impressed if you sharpenen a one eighth or 3mm drill.

One word! Drill Doctor!

on ... point

Damn this bloke makes Great tapes

Canada Russ here.. i fell asleep 3x watching this, you've convinced me to take my 200+ bits to an old pro and buy him 2 cases of beer. Lol. Great vid though.

Such a great video very informative!

The video is pretty good. I wish I could have watched something like this 50 years ago. I was about 15 and wanted to make a gymnastics high bar and parallel bars out of pipe. I was totally frustrated. Grandfather had about 118 drill bit set, every one of them dull, and the neighbor had about a 29 piece drill index, and all of them were dull also. And with all the advice I was given, all I ended up doing is grinding up a bunch of drill bits that were about as good as dull butter knives. I gave up. A few years later, I was able to talk to a machinist that gave me the information to sharpen drill bits by hand. What I do different is that I climb up the grinding wheel to remove the metal from the heel. As you mentioned, the back side of the grind should taper slightly down and away from the cutting edge. If it rises, then the heel gets in the way. About 30 years ago, I started to grind the split point bits. I was able to drill by hand, a 3/4 inch hole through slightly hardened plate steel without a pilot hole. I started with the 3/4 inch to establish where the center should be, and was going to drill a pilot hole from the center location established that was about 1/4 inch deep, but the 3/4 inch was drilling so well making DNA (Double Spiral shavings) I just continued drilling! You need a grinding wheel or something with a good 90 degree edge to make split point bits. If not, they look like the bits with a rounded corner like the one you did. I have even sharpened 3/64 bits with a Dremel tool. Sometimes they aren't so sharp even if they are quality drill bit manufacturers. I use the two 6 sided nuts as a reference. Good instructional video.

It’s been a hoot binge waiting you the last three days. I probably should get out of bed and contribute somewhere to society,but instead maybe watch just one more. But enough about me. What i really want to know is “what do you think about me?” No thats not it.. Nixi clocks! Yeah Nixi clocks. Not sur e how to spell it, or anything for that matter. But if you look you’ll find them. There’s a guy on you tube that made a steam punk one thought it was pretty cool and thought you might as well. Was hoping you mite not the bug, might, make a machinist version and give it to me because I’m to lazy to get up and have been mezmorizde but your humor and lack of skill…J/k the work you do as a machinist and entertainer is pretty damn impressive look forward to what ever else you have cookin’ thanks for all of it!!!

This is the most concise video I have ever seen on drill sharpening. Bravo Drillologist!!!
