For anyone building rustic furniture, our aluminum-body tenon cutters will cut smooth, perfect tenons with radiused shoulders. Cutters are designed to run vibration-free while being driven by an electric drill, yet still yield the same accuracy when used with a hand brace. The anodized body has been balanced to eliminate vibration and an integral level vial makes in-line cutting more accurate. To increase safety, the back end of the blade is contoured to avoid anything extending beyond the revolving aluminum body. The body has a built-in honing guide for easy sharpening of blades on a drill-press mounted drum sander. The blade is adjustable to cut the exact size of tenon required in both dry and green wood. Available in eight cutting diameters. Sizes 5/8" to 1" cut 2 3/4" long tenons and are typically used for most rustic furniture. Sizes 1 1/4" to 2" will cut 4 1/4" long tenons and are used for larger structural connections, such as bed frame to post, or fence rail to post. All sizes have hex shanks; sizes 5/8" to 1" are for use in an electric drill with a 3/8" (or larger) chuck. Sizes 1 1/4" to 2", which require more torque to drive, are for use in larger electric drills with a 1/2" (or larger) chuck. (Not for use in a drill press.) Patented. Made in Canada.
