McMaster 8834A13 Black-Oxide High-Speed Steel Drill Bit Set 114 Pieces

Drill a variety of metals, from the softest aluminum to the hardest steel.

High-Speed Steel Jobbers' Length—Our basic drill bit material is also the most versatile. These jobbers' 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.

Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.

Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.
