About Drill Bits

These jobbers'-length bits have the rigidity and length required for most applications.

Black-oxide and black-and-gold-oxide drill bits produce less friction than uncoated drill bits.

Drill bits with a split point keep centered without a pilot hole.

Cobalt Steel Drill Bit Sets

These jobbers'-length bits have the rigidity and length required for most applications. Made of cobalt steel, which has better heat and wear resistance than high-speed steel, they can run up to 25% faster and have a longer tool life.

Drill bits with a split point keep centered without a pilot hole.
