Amana Tool 55170 Replacement Cutter for #47170, 3 Piece

E-Z Change router bits are an economical alternative to standard router bits. They feature replaceable head carbide tipped cutters, saving our money by replacing only the cutters when the knives become dull, instead of the entire tool. We won't need a second bit while ours is in the sharpening shop; instead, just change the cutters. We won't even lose our set-up because the E-Z Change cutters can be replaced with the bit in the router collet. The interlocking hex design guarantees that the cutting surfaces will not slip during use.
