Specialty Diamond GB1R Glass Grinding Bit 1 Inch X 100 Grit

The Specialty Diamond GB1R Glass Grinding Bit (1" × 100 grit) is designed for fine shaping, smoothing, and edge finishing in glass, stained glass, tile, stone, and other hard materials. With its fine 100-grit surface, it delivers precise control and a smoother finish than coarser bits, making it ideal for detailed work and refined edge preparation. 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 accuracy when working on thin or delicate 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 major grinder systems.
