438W62 Taper-Length Drill Bits

$10.16

Bulk orders will be discounted, please contact us.

These bits have a straw/bronze finish that improves their wear resistance. 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.
