This precision insert plate is the same as the one that comes with the new Kreg bench-top router table*. Available as an accessory for the Kreg floor-stand table, it can also be used to create a user-made router table.
Made of phenolic resin, the 9-1/4" x 11-3/4" x 3/8" plate has a 3-5/8" through bore and a 3-7/8" counterbore to accept large-diameter bits and insert rings. It comes with three inserts with openings of 1" and 2-5/8", plus a 1-3/16" through bore/1-3/8" counterbore insert for compatibility with standard guide bushings. A twist-lock system allows fast and easy insert changes; just drop the ring into the opening and give it a short turn with the included pin wrench to lock it flush with the plate surface.
The plate is not pre-drilled; a target pattern on the underside guides drilling so you can custom mount virtually any router model. A tapped hole takes a removable pivot pin (included) for safe freehand work.
For user-made tables, a set of four levellers is available to let you quickly and precisely set the plate flush with the tabletop surface and eliminate the need to rout a supporting ledge in the opening.* Kreg bench-top tables purchased before May 2013 use an older style of insert.
