Unlike cabinet door sets, which simply cope the ends of the rails to match the profile on the stiles, the Freud Door Entry Set allows mortise-and-tenon joinery between the rails and stiles. The additional strength that the mortise and tenon provide is required for larger-scale entry and passage doors.

The key to machining the tenon is the removable top cutter and bearing assembly. When these parts are removed from the coping cutter, the remaining cutter undercuts the rail end. By flipping the piece for a second pass, you leave behind a tenon. Making multiple passes will leave a tenon of any desired length-simple! You'll need to cut the matching mortise into the stile using a router, mortiser or drill press. The Door Entry Set bits have 1/2-in. shanks and must be used in a router table. The set, to be available early 2006, includes door construction recommendations and an instructional DVD.
