405G89 Solid Carbide Screw-Machine Length Drill Bits

$49.63

Bulk orders will be discounted, please contact us.

The EgiAs coating on these drill bits resists oxidation at high temperatures and provides excellent hardness and heat resistance. The coating protects the bits from wear in high-speed drilling applications with steel, cast iron, and hardened steel with a Rockwell hardness of 35 to 50 HRC. These drill bits do not have coolant holes, so a separate hose is required to bring coolant to the bits' tip if it is needed. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.
