About Drill Bits

Drill Bits

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

Short-Length Drill Bits

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

Extended-Length Drill Bits

Short-Flute Extended-Length Drill Bits

The short flutes provide increased rigidity for drilling straighter holes than standard extended-length drill bits.
