This is a bit for cutting box joints in thin, narrow stock for tiny boxes and drawers. One pass cuts all the notches and tabs in the end of a piece 1-9⁄16″ wide. Two passes (and a bit adjustment) are needed to form the joinery on anything wider — up to a maximum of 3-1⁄8″ wide.
Box joints are perfect for joining shallow box projects and most types of drawers, and are easy to replicate simply.
There’s nothing to take apart, switch around or shim for a proper fit. Chuck the bit in your table-mounted router, adjust the bit height carefully, and rout away.
Make yourself a pusher to support the parts on-edge and back up the cuts. It’ll also allow you to clamp the parts so they don’t get pulled in by the cutter.
This close-up of a cedar boxed fitted with a box joint gives a good look at the tight, strong joinery created by this bit.
The width of your stock is critical. Perhaps the easiest approach is to rip your pieces as close to 1-9⁄16” as you can. Then cut the joints, assemble them and hand-plane the top and bottom edges of the boxes to make all the edges flush.
