Cup Wheels come in a variety of different styles and grit sizes. Some are designed for general use while others are created for specific applications. As with diamond stones the bond hardness plays an important role when selecting a cup wheel, to see the most life out of your cup wheels a bond hardness should be selected based on the "hardness" of the material you're grinding. Another option to keep in mind, with some cup wheels you have up to three grit sizes to choose from. Cup wheels have been designed to fit a variety of hand grinders along with the Terrco Edger and Flex-Shaft machines. The standard sizes range from 4" to 7" with some of the cup wheels reaching 10" diameters. A velcro backing pad is available to allow for the use of resin polishing pads.
