50CN57 Mechanics-Length Drill Bits

Bulk orders will be discounted, please contact us.

These bits have a left-hand drilling direction and can be used in reverse-drilling applications to remove broken screws from a hole. The black-and-gold-oxide finish on these drill bits lubricates the drill bit and provides some resistance to wear and rust. The bits are made from high-speed steel, which provides some flexibility and absorbs some shock and vibration.
