My invention relates to tools employed for turning off or dressing the working faces or surfaces of solid emery-wheels, and has for its object to provide for this purpose a tool which, while it shall have its cutting devices composed of metal, (steel,) and can therefore be made and sold at a comparatively low price, shall be capable of as effectually dressing the emery-wheel as a tool in which the cutting device or devices is or are composed of the much more costly substance now most successfully employed and known as "black diamonds"or "carbon points." To this end and object my invention consists in an emery-wheel dresser composed of a gang of disk-like cutters mounted fast on an arbor, which latter is mounted to turn freely on its axis in the tool stock or handle of the dresser, the said disk-like cutters being of such contour that the perimeter-of the gang shall be coincident with a cylindrical surface generated about the axis of the arbor, and each either having its sides corrugated or wave-like in form, or being set at an angle to the axis of rotation of the gang.
