I can tell by the sparks and size of the burrs that is mild steel which is not steel for drillbits since it is mild steel. why did you try to trick me???
ОтветитьI come back to this every year or so after I've destroyed every last one of my drills...It's a oldie, but a goody.
Ответитьgood quality video by a seasoned pro. Thanks for teaching.
ОтветитьChizzler, not twizzler
ОтветитьI remember when I first learned about "toolmaking" by seeing a book in a library about it once in college. It just had never occurred to me that of course there is a study and whole vocation dedicated to designing and making tools, I was just so intrigued by the whole idea of it, like what is a tool and just the nature of it all, i don't know it was a cool feeling.........im now a machinist and knife nerd and sharpener
ОтветитьAnd always make a backup copy before you start grinding !😄
ОтветитьYou talk about everything but how to sharpen bits
ОтветитьHello everyone I'm 40 and I used to be a drill bit abuser. 😥 Just spending my days one thill bit after the next and so. People told me I could sharpen them and reuse then but not how , and as I asked to the engineer in my rehab clinc he told me it was an unsafe habit. Now that I hear all the science behind it all makes sense and I feel complete, grown up and ready to make a more responsible recreational use of all my drill bits. Thank you, Tony. ❤
ОтветитьIt looked to me like the point-splitting went almost far enough, and he just needed to go the rest of the way to the apex of the chisel. I also feel like the splitting operation can be done on the edge of a wheel, but the same way the secondary grinds are done.
ОтветитьIf you can't sharpen a Drill you should not be in Engineering 😮
ОтветитьAfter 10 other videos I finally understand this art!
And great humor!
Thanks! 🙂
superb tutorage there ...
ОтветитьPerfectly explained. Thank you!
ОтветитьHoly cow the implicstion that everything is a very dull drill bit
ОтветитьOvercomplicated explanations.
ОтветитьExcellent video. Thank you so much. Well, I did watch the entire video, but half way thru it became evident to me why I've never had much luck sharpening drill bits -- didn't quite know how to put this secondary relief cut on.
ОтветитьHe said “bit” lol
ОтветитьGreat video! Really makes me want a Twizzler. Good job on getting the point across.
Ответитьgood vid
ОтветитьIn my country we don’t sharpen drill bits we replace not worth time and energy..
ОтветитьI could tell you why you're not starting with square stock, but I'm afraid to broach the topic...
ОтветитьThere 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.
Ответитьis it because the round piece of material doesn't have any edges that need to be cut to a cylindrical form?
ОтветитьWow man great info and entertaining! Thanks
ОтветитьExcellent Tony that was best video for sharpening that I have seen 🙏🏼👌
ОтветитьLove your humility. Made it very enjoyable to watch.
ОтветитьI can't remember how many times watch this video, this is gold
ОтветитьThank -you The Best Video on the subject I Have Ever Seen . And With 2.2 M VIEWS Aparently a Few Others Agree .
ОтветитьWow 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.
ОтветитьMan love your videos, you are an amazing teacher
ОтветитьI love your videos. Greetings from Europe, Estonia
ОтветитьThe wrong way? 😛🤣
ОтветитьI'll give ya 2 thumbs up gradpaw.
ОтветитьOk 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.
Ответитьwhat if i don't have a pair of nuts?
ОтветитьProfesional metal school lesson rewiev
ОтветитьAmazing video. I learned so much. Thank you!!
ОтветитьAwesome video highlighting a amazing innovative service doing good
ОтветитьI think you need to do a collaboration with thecrafsman
ОтветитьI 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.
ОтветитьI really enjoy these ten minute videos 🙃
ОтветитьDrills 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
Ответить"I'll bet that thing looks huge in the camera as compared to what I'm seeing" t.o.t.
ОтветитьI 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
ОтветитьEvery day is a school day 💚🇬🇧🌱
