Hello.

I need to drill a 1/16 hole in some 101 OFE copper. The depth is .5 inches. Can you guys tell me what drill to use and at what speed. I tried a 3 fl carbide going 6k and 24 ipm down and it did not like it. I was chip breaking at .0156 deep. Thank you.
 
Really you just need to control the chip. You CANNOT do it without a chip break, it's too gummy. I would run 500 SFM and a .005 chip load but a chip break every .015-.03".

Ditch the Carbide and use a regular old black oxide Drill.
