Beautiful box joints are ideal for jewelry box drawers, humidors, and a variety of small projects. And there are many ways to make a box joint—the easiest, fastest way is using a router bit. Therefore, to create this strong and good-looking joint, MLCS offers a ½” shank router bit with 5 (5/32″) three-wing, carbide-tipped slot cutters, 4 spacers, and a ball bearing guide to work with ½” thick stock, up to 2-7/8″ tall.
Box Joint Walk-Through
Part I: Making A Safety SledTo aid in using Box Joint Bit #7860, a simple safety sled helps prevent tear-out and speed bit height adjustment. Before making the sled you will need the following:
*Tip: Eventually, make sure the head screws are recessed so that they don’t scratch your tabletop. |
Part II: Using the Safety SledTo prevent tear-out, the sled has two ends on it so that there will be support after the bit has cut through.

Part III: Making the Box Joint
*Tip: In fact, mark the top edges of all 4 pieces to keep them oriented properly.
*Tip: If your stock wants to slide along the backer block, apply adhesive backed sandpaper to the face of the block to help hold the stock in place.
When you are done, the four pieces should form a box with interlocking corners and all pieces should line up at the same height. Usually, when you next go to use the bit, you’ll need to adjust the bit height to match the profile cut on the backer blocks. |
