Hi guys, Just a tip, If you want to drill holes in really hard ****
(stainless included) go buy the cheapest tungsten tip masonary drill and
grind the negative rake off with a bench grinder ,(make take a while) and
push hard with a drill press.
I've drilled holes in saw blades, gears, case hardened axles and of course
stainless steel. and people pay me to do it!!!

The above is also true, once you stop cutting you start work hardening (SS)

Cheers Cam

(don't tell anyone..... I may have to kill ya)

PS. you can also grind the sides off to get an exact hole size.
