Nirvana Posted December 24, 2015 Share #1 Posted December 24, 2015 (edited) So I had done drilling and lost a one of the HSS drill bits in carpet, when I found it it looked like this. Most of my bits going of like this has been broken. Take a look and ponder about it. Edited December 24, 2015 by Nirvana Canute and mtaylor 2 Quote Please, visit our Facebook page!

S.Coleman Posted December 24, 2015 Share #2 Posted December 24, 2015 What size is that drill bit? I have had a couple small tiny drill bits bend on me before.

mtaylor Posted December 24, 2015 Share #4 Posted December 24, 2015 I've bent some HSS at times and other times they break, but I find the carbide always break. That one looks like it's been stepped on.

Nirvana Posted December 24, 2015 Author Share #5 Posted December 24, 2015 I thought in order to bend a bit like this you need some heat..... maybe a carpet is good enough... The length: oh sorry, total length only 2 3/4 inches ( about 6.2 cm) long. Could have been stepped on, never felt it though...... Canute 1 Quote Please, visit our Facebook page!

mtaylor Posted December 24, 2015 Share #6 Posted December 24, 2015 It looks pretty thin then... Did you run over it with a chair? I've bent some #65's by stepping on them on carpet but then again, I'm a bit of a bull in a china shop.

Bob Blarney Posted December 24, 2015 Share #8 Posted December 24, 2015 (edited) If you have a spot of flatness around, e.g. some steel or a granite countertop, then try rolling the bit between the hard surface and a piece of hardwood such as maple. And even if you don't have a hard surface, then try rolling it between two pieces of maple for a while. It might likely work for you. You might also reduce the driving pressure when drilling -- let the bit do the work.

shiloh Posted December 24, 2015 Share #9 Posted December 24, 2015 (edited) It should have broken into two pieces. Hardness and temper is bad. If you straighten it like Bob suggests, re-harden it and then temper it and you should have a good bit. jud Edited December 25, 2015 by shiloh davyboy, Canute and mtaylor 3 Quote Link to comment Share on other sites More sharing options...
Bob Blarney Posted December 25, 2015 Share #10 Posted December 25, 2015 (edited) Try heating the bit red hot (hold it in pliers), and then stir it in vegetable oil to harden. Let it cool. Then bake in oven at ~400F for 30' or so. You can tell when it's hot 'n ready to dunk in the oil when it is no longer attracted to a magnet, but don't heat the bit beyond that point.

bluenose2 Posted December 25, 2015 Share #11 Posted December 25, 2015 You could send it out to a speciality shop that sharpens drill bits. They could possibly straighten it. Have them spin out to 10,000 to ensure there would be no wobble in it. Or just go buy a new one. Your call. mtaylor, Nirvana and Canute 3 Quote Link to comment Share on other sites More sharing options...
Nirvana Posted December 26, 2015 Author Share #12 Posted December 26, 2015 Bluenose2, I think it will be much much cheaper to dispose the drill and get another one than having it re-shaped. Think I could some 20+ drills for some the shop price, or even more... Canute, maltbyguy, mtaylor and 1 other 4 Quote Please, visit our Facebook page!

shiloh Posted December 26, 2015 Share #13 Posted December 26, 2015 That soft and bent drill bit provides you with the opportunity to learn how to straighten, harden, temper and sharpen your own drill bits, take advantage of it. jud Nirvana, mtaylor and Canute 3 Quote Link to comment Share on other sites More sharing options...
