Short-Length Drill Bits

Black Oxide

Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'- and maintenance-length drill bits.

Black-oxide drill bits produce less friction than uncoated drill bits.

Cobalt Steel Drill Bits

Uncoated

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.

Chip-Clearing Cobalt Steel Drill Bits

Uncoated

The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow. With better heat and wear resistance than high-speed steel, these cobalt steel bits can run up to 25% faster and have a longer tool life. All are jobbers’ length so they have the rigidity and length required for most applications. A split point keeps the bit centered without a pilot hole.
