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.

Short-Flute Extended-Length Drill Bits

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

Maintenance-Length Drill Bits

Also known as mechanics’ bits, these are shorter and more rigid than jobbers’ bits but longer than short-length bits.

Chip-Clearing Drill Bits

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

Short-Flute Cobalt Steel Drill Bits

The short flutes on these jobbers’ -length bits provide increased rigidity for drilling straighter holes.

Short-Length Cobalt Steel Drill Bits

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