The Diamond Bur 6 x 9mm Coarse is a professional-grade rotary tool accessory engineered for aggressive material removal and shaping. With a large cutting head and coarse diamond grit, this bur is ideal for heavy-duty grinding, carving, and deburring of hard materials such as stone, metal, glass, and ceramics. Its precision electroplated diamond coating ensures long-lasting performance, while the extended stainless steel shank offers enhanced reach and stability during use. Perfect for jewelers, sculptors, metalworkers, and industrial applications where efficiency and durability are key.
