Used to follow the outline of a pattern, these 1 3/16" template guides fit 1 3/16" through-bore base plates with a 1 3/8" counterbore, which includes all Porter-Cable, Black & Decker and Festool base plates as well as some from DeWalt, Elu, Hitachi, Makita and Skil.
The router bit protrudes through the hole in the center of the guide with the side of the guide bearing against the edge of the template. Made from solid brass, these guides are attached using the threaded brass ring nut (only one ring nut is necessary, regardless of the number of template guides you purchase). Sold singly or in a set of eight guides (5/16", 3/8", 7/16", 1/2", 5/8", 3/4", 51/64" and 1" outside diameters) and a ring nut. Ring nut also available separately.
Outside and inside diameters and height listed. The 1/2" high guides are particularly useful for letter templates.
