53KC45 Cobalt Jobber-Length Drill Bits

$11.79

Bulk orders will be discounted, please contact us.

These drill bits can drill into harder materials than would be possible with standard TiN-coated cobalt jobber-length drill bits. They are used for drilling tough, high-tensile, and work-hardened materials like titanium. The bits have a TiN coating that protects them from wear and heat, and they have spiral flutes that evacuate chips as the bits drill into a workpiece.
