439U72 Taper-Length Drill Bits

$40.15

Bulk orders will be discounted, please contact us.

The TiN coating on these drill bits protects them from wear and heat when drilling steel, stainless steel, and aluminum. Cobalt drill bits tolerate higher drilling speeds and are harder and more wear-resistant than high-speed steel drill bits. They provide some shock absorption and can be used in handheld power tools. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece.
