1/4-inch Standard Cylindrical Grinding Pin
120 Grit
These pins can be used for drilling small holes as well as for general grinding. In general grinding where a very tight curve is required, a grinding pin is often the only choice. Because the Grinding pins have diamond on the top face as well as the sides, they can be used to drill holes in glass. Once a hole is drilled, they can also provide fine grinding and elaborate shapes within the inner surface. Virtually unlimited shapes are possible by this technique.
For the Gryphette Diamond, Studio, and the Convertible Grinders.
