The biggest problem you encounter when rabbeting is trying to achieve a cut with a sufficiently deep groove. Usually it takes more than one cut to get the depth you want. With CMT rabbeting bits, the problem is solved. You can quickly produce inset doors and drawer fronts, make strong rabbet joints, mill perfect tongue and groove joints or any number of other jobs that before were time consuming and difficult. You can even re-groove old window frames with the extra long CMT ¾” (19mm) rabbeting bit.
