How to Sharpen a Drill Bit Quickly and Easily by Hand
Тәжірибелік нұсқаулар және стиль
Being a tool and die journeyman I had to learn how to sharpen drill bits by hand early on. This very simple method of grinding a new cutting lip on any size drill bit that only takes seconds. It will get you back to drilling that hole pronto!

You probably should use a drill point gage to make sure your tip is centered. And as he said, get the angles right. Should be 118° tip, but doesn't matter so much depending on what you are drilling through. The relief angles is very important. If too shallow you won't be cutting much. If too much angle, too steep, it will dig in fast and break. Should be about 12° angled down.
Good one
Great tips. Can you tell us what nuts sizes you used?

1/2” works real good but bigger will work also
What kind of disk did you use with the grinder?
What were you using on that angle grinder, one of those thin cutting discs or a thicker grinding disc?
Super helpful, thank you! What grit sandpaper ,bench grinder wheel, and hand grinder do you recommend?

Hello 60 grit on the belt sander, med grit bench wheel and I use a 4 1/2” dia grinding wheel on the delwalt
Good enough
Drill bit angle is 118⁰, your setup is 120⁰, should be close enough. I bought a drill bit sharpener. Any thing larger than 1/4" i like to use a grinder. Much easier to do than using a special made grinder. An added plus to grinding your own. You can drill a slightly oversized hole by offsetting the center of the drill point.

They're probably referring to the angle grinder. The safety police are worried about the zip disc failing.
