Can an electric drill drill copper?
Yes, but be careful:1, copper material is very sticky, so in the drilling process, the feed speed can not be fast, the amount of feed can not be too large, the drill must be sharp (front angle to large).2, the thermal expansion coefficient of copper, and melts part in the borehole, but again after cooling together, it is difficult to control precision.

The Mohs hardness of copper is 3, so an electric drill is used to drill copper.
Sure。Different electric drill bit material is different, but generally are alloy, hardness.
