Can I use masonry drill bit on metal?
The masonry bits work a heck of a lot better and don’t dance around as much on smooth steel. The only catch to using masonry bits on metal is that, since the tip is eccentric, it will drill a hole twice the diameter of the bit size. So for example, to drill a 1/2 inch hole, I’d use a 1/4 inch bit.
