These 6" x 1" flat wheels are a great choice for grinding and shaping small work pieces on a bench grinder. These wheels are narrower than our standard diamond wheels and a great choice for fitting more wheels on your grinder shaft. The electroplated diamond surface is a durable and clean way to grind your rocks and cabochons to your desired shape. These heavy wheels feature a solid steel hub and a 1" bore hole that can be bushed down to 3/4", 5/8", or 1/2".
