Ball Shape Premium Tungsten Carbide Burr - Ball Shape burrs are great for interior contour work, hole/bore deburring, and milling. These ball shape premium tungsten carbide burrs are designed for use with high-speed die grinders. The double-cut burrs will leave a slightly smoother finish than a single cut due to producing smaller chips as they cut away the material.
