The reach of the shaft for internal grinding was 4.5 inches and the device came complete with five internal grinding wheels of 3/8", 1/2", 5/8", 3/4" and 1" diameter. A 6" x 1/2" external grinding wheel was also included, together with a pulley to reduce the spindle speed to a safe 3,600 rpm when it was being used.
