439P58 Cobalt Screw-Machine Length Drill Bits

$32.88

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. Parabolic-flute drill bits have wide, deep flutes that improve chip flow and heat dissipation, which means feed rates do not need to be reduced as the drill moves deeper into the workpiece.
