With the Milwaukee TRB-1 offset base attachment, you can trim cleanly right against walls, edges, and tight corners where a standard base collides. Engineered specifically for the Milwaukee M18 ftr trim router, this attachment connects securely to provide stable and dependable guidance. Its rigid build gives you total control on hard-to-reach workpieces, eliminating the need for tedious manual edge finishing. You can easily adjust the bit depth up to 1/4 inch for precise flush cuts. The base comes complete with a drive bit and a 4 mm hex wrench so you can get to work immediately.
