Tongue and Groove Router Bits
Tongue and groove router bits cut matching edge profiles for panels, doors, frames, flooring-style work and cabinet assemblies. The joint helps align parts and increase glue surface across long edges.
Choose by stock thickness, groove width, tongue size, shank size and whether the set is used on a router table or CNC setup. Matching profiles require consistent height and fence settings.
Run test pieces from the same material thickness, check the fit before final routing and avoid over-tight joints that can split or distort panels.
