Product Details

These straight-flute drill bits have a super-hard diamond coating that prevents wear on their cutting edges when drilling composites and other tough materials. Carbide drill bits provide excellent hardness, wear resistance, and heat resistance. They require a rigid setup such as a drill press.

Straight-flute drill bits are stronger than spiral-flute drill bits and resist breaking when drilling into hard and abrasive materials, such as hardened steels with a Rockwell hardness of 35 to 60 HRC. The bits provide free-cutting action, generate minimal heat during drilling, and leave a smooth finish on the hole without requiring a reaming pass. The bits' straight flutes help with chip evacuation in horizontal drilling applications.
