These are indispensable tools when it comes to making rustic furniture, where there is a necessity to produce clean round tenons with smoothly radiused shoulders on the ends of sticks, branches, or more formal stock if you wish. With typical Veritas attention to detail, anodised aluminium bodies are accurately balanced to run smoothly in a hand-held power drill, though they work just as smoothly in a bit brace. The cutters are easily re-sharpened with a drum sander mounted in a drill press, using a honing guide built into each tenon cutter. Sizes 16mm(5/8"), 19mm(3/4"), 22mm(7/8") and 25mm(1") have 9.5mm(3/8") hex shanks and cut tenons up to 70mm(2.3/4") long. 32mm(1.1/4"), 38mm(1.1/2"), 44mm(1.3/4") and 50mm(2") sizes have 13mm(1/2") hex shanks; they cut serious tenons up to 108mm(4.1/4") long, suitable for beds, heavy chairs, and other large-scale construction. Not to be used on a drill press.
