This is a 2" diameter 2-flute straight bit with 7/8" carbide height and a 1/2" shank. The bit comes with two bearing guides for cutting 5/8" or 3/4" rabbets at any depth you choose. Optional sets of bearing collars make this the most versatile rabbet bit on the market.
The Superabbet takes less time to set up than a dado, lets you select widths more precisely than with an edge guide or table fence, and lets you take a hand-held router to the work for any rabbet on the menu.
