Grinding wheels, called mounted points, are used in the benching phase of polishing. Mounted points come in various shapes and sizes. Larger ones have 1/4″ shanks and smaller ones 1/8″ shanks. They are always used in die and pencil grinders. Mounted points are used primarily to install radii or for the smoothing of machined radii. With care and practice they can also be used to blend surfaces and remove rough cutter marks and EDM in tight areas.
