Specialty Diamond GB1H Glass Grinding Bit 3/8 Inch X 50 Grit

The Specialty Diamond GB1H Glass Grinding Bit (3/8" × 50 grit) is designed for aggressive grinding, shaping, and stock removal in glass, stained glass, tile, stone, and other hard materials. With its coarse 50-grit surface, it removes material quickly and is ideal for heavy shaping and edge preparation before finer finishing. The bit is made from a single-piece brass body that resists fatigue cracking during high RPM use and vibration. A specialized bonding process secures multiple layers of diamond for extended wear life and consistent results. Uniform diamond bonding reduces chipping and provides better control when working on delicate or thin materials. This bit mounts with a universal arbor and set screw design that fits 0.312" (7.92 mm) spindles, making it compatible with Inland grinders, WIZ, Super WIZ, Wizling CG, Wizard IV, Impulse, WIZ CG, and other popular grinder systems.
