$244.73

Bulk orders will be discounted, please contact us.

The bright finish on these drill bits is not affected when the bits' cutting edges are resharpened. High-speed steel drill bits provide more flexibility and absorb more shock and vibration than cobalt and carbide drill bits, making them suitable for use in manual drilling machines and handheld power tools. They may leave a rough finish on the hole. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece.
