O.k., this officially drives me nuts. I just want to drill 1/2" holes through thin (up to 1/8") nickel silver, brass, or copper spacers. I have tried all kinds of drills and it keeps annoying the heck out of me. The last ones I tried were drills with a little pilot thingie, and at first they seemed to work, but tonight I did't get a hole in a 3/32" piece of nickel silver amd when I pressed harder, the damn thing - piece and drill- started glowing.... I usually start with a smaller one of 1/4" and then try with the 1/2".
So, what drills to use? Anything else to pay attention to? What drill press speed, should I use something for cooling? I start feeling really stupid but i hope I am only the wrong tools... Thanks,
