... I am about to order more drill bits
and I need advice. ... David Lowry
Dave,
We bought some solid carbide drills (not burrs) from
McMaster Carr that work very well with carbon. These are
expensive little buggers and are extremely brittle. If you bind or try to bend
one it shatters instantly--the end result for all six #40's we bought.
The #30 and larger ones seem to be strong enough to withstand a small
amount of abuse--we actually have a couple of these left from the original
six. I think McMaster calls them "PC board drills." Hope this
helps.
