Simpli-Switch Tongue and Groove System with Case

The Whiteside Router Bits 360 Simpli‑Switch Tongue and Groove System gives woodworkers twelve precise tongue and groove router bit setups from a single matched set. Built around a 1/2" shank and a 1‑5/8" large diameter cutter, it replaces multiple dedicated bits while maintaining tight fit and repeatable results.

This system solves a common shop problem: dialing in different tongue and groove sizes without stacks of shims or extra cutters. Tongue thickness is controlled by swapping cutters while bearing changes set tongue depth. The result is fast size changes that stay consistent from cut to cut, making it easier to match panels and frames.

By combining four tongue thicknesses with three bearing‑controlled depths, the set covers a wide range of joinery needs while keeping setup straightforward. One cutter and one spacer change is all it takes, so workflow stays focused on cutting, not recalibrating.
