The trimming bits are available in 3/4" or 1/2" diameters and have beveled cutters for little or no filing. The 3/4" bit is for 1/2" horse routers or bigger for very smooth cuts (ideal for router tables) and the 1/2" diameter bit is for small hand-held laminate trimmers. The trimming bits can be resharpened. Ships via UPS/FedEx ground.
