Whiteside Multi Side Bit - 8 Sides, 1/2 in. SH is a versatile router bit designed for creating precise joints on multi-sided projects like planters, columns, and barrels. Known as a "birds mouth" bit, it simplifies the process by routing a single notch on the edge of each board, enhancing both ease of assembly and glue surface area. This bit allows your projects to be left flat-sided, or turned, planed, or sanded to the desired shape after assembly. It is intended for use in a router table with a fence and works specifically for 8-sided objects with material thickness up to 7/8 inch. You can achieve either flush or ribbed construction, with the option to trim outside corners for a flush look. Adjusting the bit’s vertical position controls the notch depth and rib size, giving you flexibility in your final design. Crafted with a carbide-tipped, two-wing design, this bit ensures durability and precision. Manufactured by Whiteside Machine Company in Claremont, North Carolina, it features a 1/2 inch shank size and a 1-3/4 inch large diameter. Model Number: 3508
