$29.15

Bulk orders will be discounted, please contact us.

The TiNAl coating on these drill bits provides a low-friction surface and is suitable for drilling most materials. 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. These bits do not have coolant holes, so a separate hose is required to bring coolant to the bits' tip if it is needed.
