Product Summary

The Specialty Diamond GB1G Glass Grinding Bit (1/4in. × 200 grit) is designed for ultra-fine grinding, precision shaping, and detailed edge finishing in glass, stained glass, tile, stone, and other hard materials. With its extra-fine 200-grit surface, it provides superior control and the smoothest finish, making it ideal for delicate work, intricate designs, and final edge polishing.The bit is built 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 protects fragile or thin materials when working on fine details.This bit mounts with a universal arbor and set screw design that fits 0.312in. (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.
