To make simple, fast work of mortice-and-tenon joinery, this system uses power tenon cutters and matching countersinks to produce strong flush-fitting joints in round or dimensioned stock. The cutters produce a symmetrical tenon with a 60° tapered shoulder that fits neatly in a countersunk socket. The main blade shapes the tenon and shoulder, while a finishing blade smoothes the tenon to a consistent diameter and cuts a slight relief at the base of the shoulder to ensure it seats flush. The finishing blade's cutting depth is adjustable, so you can fine-tune the tenon diameter for close fit.
Cutting capacity for all sizes is 1 1/2" greater than the tenon diameter. Sizes 5/8" to 1" cut 2" long tenons (not including the tapered shoulder) and are for use in drills with a 3/8" or larger chuck. Sizes 1 1/4" to 2" cut 3" tenons and are for use in drills with a 1/2" or larger chuck. All have hex shanks and anodized bodies, and can be used in an electric drill or hand brace (not for use in a drill press).
To shape the tenon socket to match the tenon shoulder, we offer two sizes of countersinks separately, each with interchangeable bushings sized to match our tenon cutters.
