Whiteside · Tongue and groove and lock miter bits
Whiteside 3373 straight tongue and groove set
1/2 in

When to choose it
The 3373 supplies separate cutters for the tongue and the groove. Whiteside lists it for 1/2- to 1-1/4-inch material, so start by measuring the actual stock thickness.
The maker sells the 3373A tongue cutter and 3373B groove cutter separately. Confirm the 3373 set if you are starting without either cutter and want the matched pair.
