Desciption

This 1/4" Standard Grinding Bit is a versatile cylindrical grinder pin designed for precision work in stained glass, fused glass, mosaic, and coldworking applications. Coated with high-quality diamonds on both the top face and the sides, this bit allows you to grind, shape, and drill with accuracy.

Use it to drill clean holes through glass, then continue refining the interior with smooth, controlled grinding. It's perfect for creating detailed inner contours, keyhole openings, jewelry cutouts, and other intricate shapes that standard grinding bits can’t reach.

Ideal for:
✔ Drilling small holes in glass
✔ Fine interior grinding
✔ Shaping inner edges and contours
✔ Jewelry and detailed glasswork

Compatible with most standard glass grinders.
