To make simple, fast work of mortise-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, each with interchangeable bushings sized to match our tenon cutters.
The small countersink comes with 5/8", 3/4", 7/8", and 1" bushings; the large comes with 1-1/4", 1-1/2", 1-3/4", and 2" bushings.
