drill a hole in a knife blade?

You could spot anneal and then drill. The easy way to do that would be to use a square cut section of drill rod the size of the hole you want. Then run it against the spot you want to drill. The friction will heat that spot and anneal it so you can drill it.

6000 rpm is more like it. I'd spin as fast as I could, use a steady feed and not rub it to death. SS is prone to work hardening.

button hole.

grind to fit.

hard stainless

or a

oil or annealing?

Try this one instead:

I've had good luck with these and have several different sizes on hand. Turn it slow with heavy feed and make sure it is held solid. Best done in a mill. I've drilled through easy-outs, ball bearings, bearing races, band saw blades etc etc.........so it should cut your knife blade......IMHO phil

Brand new carbide bit with lube, very slow rpm (hand brace speed) very high pressure.

You might want to search the archives of rec.knives. The same question was debated there some time ago. I do not remember the details. Or you can post there. The group has deteriorated due to idiotic trolls, but a few die-hard experienced knife makers still monitor and post there.

Don't worry about the drill, it will last and can be red hot. The blade should be cut long before that. Yes cutting it in a pool of coolant and flood isn't a bad idea.

Good luck. I found the knife I lost - I turned my chair upside down for a second time - it was lodged within and finally fell out. I had no idea where it was.

Good luck!

I've had good luck with cheap masonry bits when I only needed to do a few holes. (I convert old files into knives. )

Center punch and drill at ~1200 RPM.

What goes through un-annealed files should go through your blade.

Smokey mountain knives used to carry a thumb stud that clamped on with a screw. You might be able to find one or make one. Karl

I wouldn't use a masonry bit - better than nothing.

The design isn't for precision holes. Just one in that cement...
