Modifying Drill Bits for Brass


H


ERE’S A TIP WELLknown in the metalworking field, but perhaps
not common knowledge among woodworkers. When drilling
soft metals such as brass, always grind or stone a small flat on the bit’s
cutting edge. This flat prevents the drill from chattering and results in
much cleaner drilling.
