Rockler 45° Lock Miter Router Bits – 1/2” Shank

The interlocking fingers of our Lock Miter Router Bit provide a strong mechanical locking action that makes it much easier to clamp. There is no tendency for the joint to slide out of alignment under clamping pressure, and the wedged tenons tighten up nicely for a strong corner joint. The increased long grain gluing surface also helps to strengthen the joint over a basic rabbet or butt joint. Machining parts with the Lock Miter Bit is easy—with the bit height set, one part is cut horizontally on the router table, while the corresponding part is cut vertically. The bit is ideal for joining drawer boxes, cabinet parts, and for building 4-sided columns.

Note: To make setting the cutter height easy and fool-proof (Applicable for Item 22627), use the Rockler Router Bit Set-up Jig (53817, sold separately) to center the bit on your stock.
