Find triangular drill bits suited to your next project.

FAQs

Triangular drill bits cut wood, soft metals, plastics, and some composites when used at appropriate speeds.

Triangular bits have three flat cutting surfaces instead of spiral flutes, creating non-round holes for specific applications.

They work in any standard drill or drill press that accepts round shank bits of the matching diameter.

Yes, triangular bits can be sharpened with a fine file or bench grinder while maintaining the original three-sided geometry.

Triangular drill bits come in various diameters to match different project requirements and hole specifications.
