    SM-Type Carbide Burrs                

    Carbide Burrs are made of tungsten carbide, a metal that is extremely hard (about three 

    times stiffer than steel) and of very excellent wear-resistance and can withstand high 

    temperatures, sometimes regarded as rotary files and come in many shapes and sizes.

    The Carbide Burrs are used for shaping, smoothing and material removal (debur) on hardened

    steel, stainless steel, cast iron, nonferrous metals, fired ceramics, plastics, hard woods and other hard materials.

    Typical applications:

    weld preparation

    weld smoothing,




    Scale removal.
