Amana Tool 53600 Quadraset 1-7/8 Dia x 1/8-23/32 x 1/2 Inch Shank Sanders soft foam ear cushions andThe Quadraset is an adjustable slotting assembly that includes 1 8," 5 32," 3 16," & 1 4" two wing cutters, a 1 2" shank arbor with a pilot bearing, and a handful of spacers, washers and shims. Conceptually it is like a table saw dado stack set. You can use the cutters individually on the arbor, or you can combine two, three or all of the cutters on the arbor. Thus you can cut slots that range in widths from 1 8" up to 23 32" in 1 32" increments.
