I have been drilling holes into lead for the last 20 years, first with power drills and lately with electrical screw divers (they are slower and more controllable), and I never hurt anything. Of course you have to be careful and drill against a base and shit, that's clear....
the only thing that happens rather often is that the lead breaks the drills if I am not fully concentrated
what ist this?
"Archimedes screw pin vise"
a manual drill?
I can't use manual drills because of my tendonitis that pops up very regularly, so I had to come up with solutions for working around that very early
