Cutting wheels, or cut-off wheels, differ from grinding wheels in their function and structure. Where grinding wheels use an abrasive to grind large pieces of material off a workpiece from a shallow angle, cutting wheels typically make narrow, precise cuts at 90-degree angles.
Cutting wheels or cut-off wheels have different applications and structures than grinding wheels. Cut-off wheels cut small material workpieces at 90-degree angles, whereas grinding wheels grind large material workpieces from a low angle. As a result, cut-off wheels are quite thinner than grinding wheels.
