Drilling nickel silver and copper spacers?
I think I asked that before but I didn't find it. How do you guys drill through nickel silver, copper, and brass spacers, something between 1/16 and 3/16". Of course, I have been doing this for a while but it drives me nuts every time. The last drill I tried was a DeWalt titanium drill with a pilot tip that went trhrough the first one and then I tried drilling a piece of stainless steel spacer fron Jantz and the thing almost melted on me. After that, I could not even go through 1/16" of n.s. Anymore. There has to be a way I haven't discovered yet, nobody would do this if there weren't an easier way. Oh, and we are talking 1/2" holes here. I predrill the pieces with the same series 1/4" using cutting oil. Once I try opening the predrilled hole with the 1/2" bit, nothing goes anymore. Makes me feel really stupid...
thanks for your tips,
