For anyone building rustic furniture, the Veritas 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.
