$35.11

Bulk orders will be discounted, please contact us.

These drill bits come in standard sizes expressed in millimeters. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece. The bright finish on these drill bits is not affected when their cutting edges are resharpened. The bits do not have coolant holes, so a separate hose is required to bring coolant to the bits' tip if it is needed.
