Twist Drill Bits
what metal type can twist drill bits drill?

I have been able to drill into or through almost any type of metal with a high speed electric drill, even a battery operated one. The drilling time varies according to the type and thickness of the metal. It is true, at least in my experience, that with certain types of metal a less sharp (but not completely dull) bit is more effective.
