1 3/16" Router Plate Inserts

To minimize the risk of kickback and splintering, these inserts reduce the size of a base plate's through bore and support stock next to the bit. Machined from solid brass, they fit any base plate with a 1 3/16" through bore and a 1 3/8" counterbore*, and attach with the threaded ring nut. Only one ring nut is necessary, regardless of the number of inserts you purchase.
