Use these round-faced carving wheels when doing carving, intarsia, channel work, stained glass and other applications that require curved edges. Use the 1/4" and 1/2" widths for narrow grooves and the 1" wide for larger ones. Four wheel diameters increase your choices. All carving wheels can be used on the Titan. All but the 8" wheels can be used on the Genie. Only the two and four inch wheels can be used on the Pixie. These wheels can also be used on most other grinding machines that have standard arbors. Wheels are bored to 1" and come bushed to fit 3/4", 5/8" and 1/2" arbors.
