Grooving planes are used to cut straight grooves, or rabbets, into a working piece. They are traditionally used for drawer bottoms or rear walls. They can be used in conjunction with tonguing planes, which create two parallel slits in a piece of wood. The grooving plane can then dig out the excess material and create a clean groove. Other names include dado planes, ploughing planes and matching planes when combined with a tonguing plane.
