Whiteside Multi Side Bit – 6 or 12 Sides, 1/2 in. SH is a versatile router bit designed for creating precise joints in multi-sided projects such as planters, columns, and barrels. Known as a “birds mouth” bit, it allows for easy assembly by routing a single notch in each stave or board, increasing glue surface and simplifying construction.

For 6-sided projects, the exterior side is cut face up, while 12-sided projects require cutting face down. The bit supports both flush and ribbed construction, with ribbed recommended for 12-sided items to maintain strong joints. Adjusting the bit height controls the rib size, allowing customization of the joints appearance and fit. Made with carbide-tipped, two-wing construction, it is designed for use in a router table with a fence to ensure accuracy and ease of use.
