ARGH!! can't drill small hole in copper

I'm trying to drill a #60 hole 1/2" deep in copper. So far, I've broke three drills, and just now, a very small center drill. I've tried 2000, 1000, and 500 rpm. Also extremely, extremely, small pecks. Never made it 1/4" yet. Am I work hardening the copper? Need a special lubricant? Any suggestions? I only have two more drills left, so I thought I'd ask before breaking them all. -- An apple a day keeps the doctor away. Two apples a day gets the doctor's OK. Five apples a day makes you a fruit grower, like me. Karl Townsend in beautiful Dassel, Minnesota STOP GUESSING! You are wasting everyones's time. Copper is a soft metal compared to steel. Clearly you have the wrong tool for the job. I dont know what the right tool is. Like everyone here I am looking for the answer and not finding it. STOP GUESSING! Let someone who knows answer it instead of adding to the confusion. |
