Amana tool 54273 Carbide Tipped Multi-Sided Glue Joint 45 / 45 Deg x 1-1/2 D x 7/8 CH x 1/2 Inch SHK Router Bit

If you’re looking for a better way to construct multi-sided boxes, planters, and columns, then look no further. With these bits, there’s no need for complex miters and time-consuming set-ups. Instead, simply choose the bit based upon the number of sides on the box, rout the joint, and assemble. Unlike a miter joint, the joint created by these bits aligns itself. And the joint stays in alignment while gluing, no more slipping and sliding out of position.
