THE USE & CARE OF DRILL BITS part 3 of 3 Sharpening tubalcain

[ajkqy1]

thank you so much!! u r simply the lighthouse that enlightens this world...

[ScagSWZU]

Mr. Cain

What do you think of the drill dr?

[bradenn]

Ha! I agree with your thoughts on the drill sharpening fixtures, hahahaha. That was very unexpected! Great video, It would be awesome to be a student of yours.

[nosloppyagape]

Hahahahah thts what I think of novelty gimics

[nzlqzb]

After viewing several videos on drill bit sharpening yours was by far the most informative and professional. You mentioned restoring damaged bits by cutting off a portion of the tip and I assume grinding it down. I have a large project using stainless steel which has burned a few of my bits. Could you create a video detailing how to restore these damaged bits ? It would be greatly appreciated considering the expense of these bits. Thanks in advance.

[spilperson]

Thanks so much for this and all of your videos. I am 45 years old, and I am ashamed to say I have never understood drill bit sharpening until now. You made it crystal clear for me. Thanks again.

[wjlhwe]

Thanks for the videos, I learned a lot. Quick question. What brand of drill bits would you recommend for doing basic metal fabrication. Mostly 1/8" to 1/4" steel. I would like to invest in a decent set of bits that will last me a while.

[stevehoughton]

Dear Sir, thank you for this awesome how to video. Not only have I learnt how to finally sharpen my bits, I am going to take this video over and show my 70 year old neighbour how to do it. I am sure he will love this as much as I have. Thank you so much for your excellent teaching style and for passing your wisdom and experience on to others. Kindest regards from Australia.

[HmsSulaco]

Grumpy old man with experience ;-), thanks for sharing this.. "Perhaps you have a sharpening jig hmm And those are good to SMASH and get rid of, absolutely useless !! haha you made my day..

[subsonicnat]

used to grind drills TEN THOUSANDTH of an inch by EYE, They were good then, used to grind them for the Fitters.. Sadly my eyesight is no longer any good, but does bring back memories.lol.

[IGotN0]

LOL you should smash more things

thanks for the videos

Very good for an apprentice like myself

[arnoldcustom]

I did the very same as he did but only to my drill doctor some one bought me, NO DAM GOOD

[mowersman]

Thanks, this has been incredibly helpful, I've always just bought new cheapo bits when mine get blunt, but hopefully as I get some practice at this, I can get some better quality ones.

[Dubbie99]

Very good video. 1000 times better than Experts Exchange one.

[d25j4149]

Thanks very much , Learned more in short video than in an hour of reading a how to manual. I thought those drill sharpening attachments were not that great.

[d25j4149]

 Thanks very much

[canals22]

Howdy, hey y'all, is it possible fo "freshen-up" a drill bit if one has no power tools ? By using a file ??

Think of a "field" condition, like in a sailboat or out in the ranch...

Godspeed

George

[mrpete222]

@canals22 Not a file. A hone and 3 hours.

[canals22]

@mrpete222  Wow... Thanks !

[mrmatt2525able]

Before i just winged it and eye balled it now ill do it the right way, thank you sir

[bunberrier]

Thanks for sharing your knowledge, tubalcain! Too bad we can't share a bourbon and watch the sun go down together at the shop door when you are done teaching.

[eartaker]

I couldn't stop laughing at 4:54... it caught me off guard when you started hitting the jig =]

[stubblyhead]

You are awesome. If I could have a third grandpa, I'd want it to be you.

[Dieselolds]

HSS might be good but i think the chinese stamps HSS on even the lowest qualty bits...

[pilothawk400]

Great tutorial! You sound just like Jimmy Stewart :)

[AntillRS]

i love coming across great little videos like this. thanks for sharing your experience and know-how

[specallez]

Thank you! I'll have to try sharpening my collection of dull bits. Often, my drills drill more triangular holes than round ones, is this because they are not sharp, or something else ?

[davetileguy]

Why would a "machinist" eyeball his drill bits? Drill Doctor $50.00

Tip!! Two nuts held together create the proper angle,hold the finished bit in the v of the two nuts for proper angle.

[shonuffisthemaster]

@davetileguy

Because that's the way machinists have been doing it, accurately, since the invention of the twist drill. The drill doctor also only sharpens a range of bits well, on larger ones it will put a concave edge on the bit, and it doesn't do great with smaller ones (I have successfully sharped 1/16" by hand) and it has the problem of being very laborious (and hard on the expensive diamond wheels) if you need to completely regrind a large bit.

[davetileguy]

@shonuffisthemaster He's eyeballing it,that may work but its not accurate,the drill doctor is just a cheap jig thats better then your eyeball! also diamond is going to "cut" a new surface and it's going to stay flat a belt sander isn't going to last as long,also diamond wheels are not expensive,being in the stone and tile buss I have seen their cost come down over the years.

[shonuffisthemaster]

@davetileguy

Wheels for it are $20, belts are under $1. Aluminum oxide, silicone carbide, boron carbide, and diamond all "cut" steel, the difference is mainly hardness and Friability. I can go to a 9 micron finish, the DD is limited to 180 US grit (80 micron). The DD produces a concave face on larger bits for some reason, the platen on the sander is pretty flat. Never underestimate what the human eye and hand together with skill can achieve, hand scraping can produce surfaces flat to 0.000040”

[davetileguy]

@shonuffisthemaster Sanding belts are not one Dollar and your human eye cannot determin 0.000040 LOL! If I gave you a pile of drill bits you couldn't tell the difference between one that was 1/2 a degree off,have you thrown away your dial indicator and cali and calipers Mr eyeball?

[YellowKard]

Thanks for this video!

[1934hotrod]

very interesting thank you, learned from this...

[Mr19601965]

thanks to you i can run a lathe

[AndreaGanora]

Really well explained and informative video, as allways.

Thank you very mutch for the time and efforth you put in sharing your knowledge, it's greatly appreciated

[batvette]

Now I know why that drill bit sharpening jig I bought never worked.....wrong application! It seems it's for sharpening hammers!

(II have one absolutely identical to that one, even with the instructions I couldn't figure out what to do with it)

[mrpete222]

@batvette That was a good one!!!!!

[cannonball666]

I hope you never get mad at me while your holding a hammer, Tubalcain.

[cannonball666]

I hope you never get mad at me while your holding a hammer, Tubalcain.

[saswsz]

thank you 4 that video :) can you please tell me haw to Sharpening the flat head steel drill .?

[st00pidity]

would uneven sides cause smaller bits to walk on mild steel? And also Thank you for your knowledge!

[st00pidity]

would uneven sides cause smaller bits to walk on mild steel?

[mrpete222]

@st00pidity Not walk, but drill an oversize hole. This is sometimes done on purpose.

[JamesRedish]

Great video, thanks for taking the time to share.

LOL @ 4:55>

[puppetfilms]

I am a self-taught third generation machinist who makes very small parts. I just wanted to say thank you for sharing your wealth of experience!

[Thetruthishere11]

great vid. this applies to metal drilling bits too?

[makedoandmend2]

helpful video

[mezansky]

great video - thanx for posting it

[that1s10]

Really, fantastic. Thank you.

[volkaholic]

great video, thanks a lot for the help!

[jamesjeffh]

You just saved me gobs and gobs of money.

[gbowne1]

thats one huge MONSTER drill bit!!!

I don't use 118 degree bits.

[matt986423]

thanks

[SEGROCKWORKS]

Thank you. Now I know.

[oompsta]

I see Brendan did the same thing as I - HA HA I loved the hammer!!

[PJStein]

Thanks for sharing your knowledge!

[AkGrayWolf]

Thanks Lyle, I have been hoping you would do a piece on drill bits and you were way more thorough than I had hoped. I REALLY appreciate you taking the time to pass on some of you knowledge and experience. Now if I can get a bit sharp, maybe it won't be just dumb luck. Thanks.

[mrpete222]

Thanks--you can do it.

[thomastholin]

The BEST video I've seen about drill-bit sharpening!!!

Thanks Tubalcain

[trumpy81]

Thanks Tubal, I've tried to sharpen drill bits in the past and I always failed to get a sharp properly cutting drill, that is until now!!

After watching your videos I can now sharpen a drill properly!!

Thanks so much for sharing your knowledge

[SlowEarl1]

Thank you!!! As always the best learning videos .This Country needs more teachers like yourself.

[mrpete222]

THANKS

[whotoinfinity]

Sir, thank you again! I learn something new with each of your series. Just this past weekend I was drilling out rivets holding in upper ball joints on my wifes Blazer. On the second one, I skipped the middle sized drill, and it was slow going and dulling of a new drill... I realize now that the chisel must have been larger then the pilot hole. Oh well, live and learn right? Now I can practice on that brand new drill I dulled...

I also liked the Jig Smashing... LOL

Gill

[electramechdotcom]

Thanks for all the videos, they are very informative. You should have your own TV show! Please bash more junk with hammers.

[jfco61]

I watch your vids and I learn a lot

If your keep uploading I will keep LEARNING.

Thanks Mr Pete.

[cdbflynow]

A fine trilogy - thank you for your efforts.

Loved your "hissy fit" about the sharpening aid. Such treatment is well deserved by that unit ( I have one). I also have one that works well, though is long out of production. Maybe I can post it one of these days.

[russtuff]

fantastic series!

[camochannel1]

sir, thank you so very much.

[ottersbro]

tubalcain your you have a wonderful way of teaching, i have learned tons watching your videos.

thank you so much.

[redoorn]

the puff of dust out of your circular file is a fine touch to your opinion of the novelty gimmicks.

[mrpete222]

Thanks--I'm glad like my first attempt at "special effects".

[timothysvec]

Thankyou sir. Your video was great! I look foward to seeing the casting of your engine in the spring.

[baconsoda]

Super! This is great information and very timely because I have a load of blunt drill bits that I need soon.

It took me over 12 minutes to watch this because I replayed the 'smashing jigs' bit about fifteen times! LOL.

Best Wishes, Brendan

[happymark1805]

I'm using the same method on the grinding wheel, for smaller bits buy some cheap reading glasses (+2,5) , there is one thing, bits for plastic and copper need to be sharpend with other angles, would be nice to know what angles, can you make a video on that ?
