Drills are solid cobalt steel and outlast high speed steel (HSS) bits 15 to 1.
Speed Recommendations:
Drilling speeds should be between 500 and 10,000 rpm. All drilling should be done with a lubricant. The harder the material (metal) to be drilled and the larger the hole size, the slower the drill speed.
