8mm Shank Tongue & Groove Joint Assembly Router Bit
Tongue-and-groove (T&G) joints form sturdy, interlocking connections with lots of glue surface area for all sorts of woodworking applications: cabinet door joints, self-aligning shelf edging, web or face frames and even carcass assembly. There are DIY applications for this joint too, such as V-groove wainscot or wood flooring. Cutting the narrow centered groove and the corresponding tongue to fit into it doesn’t take a dado blade and table saw. You can do it all at the router table easily with three different cutter approaches.

How to use Tongue & Groove Router Bit:
Generally speaking, it’s easier to cut the groove of a T&G joint first, then mill the tongue to fit the groove. A 1/4-in. straight bit or spiral upcut bit makes an ideal groove-cutter into the edge of a workpiece. Mark your workpiece with a couple short reference lines for centering the bit on the thickness of the wood. Hair-splitting accuracy isn’t crucial here — just get them close. Install the straight bit in your router table, and raise it about 1/4-in. Adjust and lock the fence so the bit is centered between its reference marks with the workpiece held in place. Clamp a featherboard to the table to press the wood firmly against the fence.
Push the stock through the bit using moderate feed speed. Once you’ve completed the first pass, clear out any debris from the groove, then flip the workpiece end-for-end and make a second pass (see Photo 1). Two passes will ensure that the groove is perfectly centered. Now raise the bit about 1/8- to 1/4-in. at a time and repeat the process until you reach the groove depth you want. Note: It’s a good idea to make the groove about 1/32-in. deeper than the tongue will be long; the open space at the bottom of the assembled joint will give the glue some room to migrate so the parts close properly.
