Greetings. I have to drill 35, 13/16" holes in a 6" mild steel pipe, .430" wall thickness. I want to be able to drill completely thru the pipe to insure reasonable hole alignment. I'll be using a magnetic drill.
Should I use a conventional twist drill or a core/shell drill for easiest drilling?
Thanx.
