High-Speed Steel Drill Bits

Jobbers' Length Morse Taper Shank |

Our basic drill bits are also the most versatile. Cut holes in a variety of metals, from the softest aluminum to the hardest steel.
Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.
