# Mori Kobo Stained Glass Tools This is a bit used for grinding glass in stained glass. It's half the price of genuine Glaster products, but it grinds well. The size is the general 3/4 size. The grit is a coarse type. Because it is coarse, it is suitable for those who want to grind glass vigorously with a router. You can check how coarse it is in the second image. Since the shaft diameter is the same as Glaster and Inland, it can be used with any router. # Mori Kobo Stained Glass Tools Stained glass, glass cutting, mosaic, grinding, fusing, router, grinder, tile, DIY, craft, coarse grit
