Hi Mr. Zekelman, All:

	With regard to drilling copper, Machinery's Handbook says that MOST
copper drills similarly to steel, but likes higher tooling speeds.  Soft
copper should produce "small, easily broken chips" Some alloys are
different, and are tough to deal with.  They produce "long, stringy
chips".  Some cutting fluid is also recommended.  Do you know the type
of copper you're using? (UNS number: should be C1xxxx).  If so let us
know, and we'll find the exact properties of that alloy.

Hope that helps...

Winston
