407H05 Non-Coolant-Through High-Speed Steel Jobber-Length Drill Bits

Bulk orders will be discounted, please contact us.

The black-and-gold finish on these drill bits lubricates the bits and provides some resistance to wear and rust. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece. They also have flats on their shank that help prevent the bits from slipping in a drill chuck when drilling at high speeds or under heavy loads.
