A great way to join up many multi-side projects such as planters, columns, and barrels. The 3508 can be used for eight sided objects. Very straightforward, this joint requires routing a notch in only one edge of each stave (side). Notching also improves ease of assembly and total glue area. All bits are 1/2” shank and designed for use in a router table with a fence guide.

Claire ★★★★★

I built an octagonal planter this weekend and this bit made the birdsmouth joints effortless. The cut is clean and consistent, saving me a ton of setup time.

Edward ★★★★★

Used this to cut the eight notches on a hexagon planter I'm building and the fit was dead on right out of the box. The notch cuts clean enough that I barely had to sand the joints before glue-up.

Ava A. ★★★★★

First time cutting birdsmouth joints and the notch lined up dead on for all eight staves. The bit is beefy and stayed sharp through a full cedar barrel project. No gap-filling needed on the glue-up.
