Specialty Diamond GB1L Glass Grinding Bit 3/4 Inch X 50 Grit

The Specialty Diamond GB1L Glass Grinding Bit (3/4" × 50 grit) is designed for aggressive grinding, shaping, and stock removal in glass, stained glass, tile, stone, and other hard materials. With its large 3/4" diameter and coarse 50-grit surface, it removes material quickly and is ideal for heavy edge preparation and shaping before 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 performance. Uniform diamond bonding reduces chipping and helps protect delicate or thin materials when grinding aggressively. 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 major grinder systems.
