441J30 High-Speed Steel Screw-Machine Length Drill Bits

$3.95

Bulk orders will be discounted, please contact us.

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. The bright finish on these drill bits is not affected when the bits' cutting edges are resharpened.
