Groove edges for T-moldings, splines or biscuits, and other purposes. Rout tongue-and-groove joinery. Each assembly includes a cutter, bearing for a 1/2" deep cut, and either a 1/4"-, 3/8"-, or 1/2"-shank arbor. Use in a handheld or table-mounted router. All assemblies include cutter, arbor and ball bearing.

Flush trim bits cut the wood on your project so that it is flush with the template edge. The downshear cutting edge moves the chips away from the router.
