A carbide ball burr features a fully spherical cutting head designed for precision shaping, contouring, and smoothing curved surfaces. Its rounded profile makes it ideal for creating radiused edges, hollowing or carving rounded recesses, enlarging holes, and finishing internal contours that flat or cylindrical burrs can’t reach effectively. Made from tough tungsten carbide, a ball burr maintains sharp cutting performance, resists heat and wear, and delivers clean, accurate results on metals, stainless steel, hardened steel, stone, wood, plastics, and other tough materials. It is commonly used in metalworking, fabrication, automotive repair, die grinding, woodworking, and detailed finishing work where smooth curved accuracy is essential.
