Abstract
A power operable bone facing cutter has a body with a pilot hole or stem for orientation with the bone to be faced. A cutter disk is removably fastened to the working end of the body and has a cutting edge lying in a plane perpendicular to the pilot axis. The cutting edge extends from a circle centered on the axis, outward to an outer circular edge. The cutting edge is at an angle with respect to a radius from the axis to cut toward the axis as the cutter is rotated. A chip escape slot is provided in the disk and body above the cutting edge. The rest of the bottom surface of the cutter disk is flat to provide a supporting surface spaced at a gage height from the plane of the cutting edge to provide optimum cutting while the supporting surface prevents excessively rapid or deep cutting, thus producing a skiving action.
