Carbide Burrs

KnKut Carbide Burrs also called Rotary Files, are solid carbide, double-cut tools built for deburring, shaping, and rapid stock removal on hardened steel, cast iron, stainless, aluminum, and other tough materials. The double-cut design with left-hand flutes reduces pulling and keeps the burr tracking cleanly, giving you better control at slower speeds. Available in a full range of profiles, cylindrical, ball, egg, flame, round tree, and cone in 1/8" and 1/4" shank sizes for die grinders and rotary tools. A go-to for fabricators, welders, auto body shops, and machinists who need precision material removal without grinding wheels. USA-made.

Burrs handle the finishing, the holes come first. Drilling hardened steel? See our carbide tipped drill bits. Truing or deburring holes? Reach for our car reamers.
