Three tools in one - a cutting gauge, a pin gauge and a wheel gauge. The unique swivelling pin/blade chuck takes either a pin or a blade that locks in place (after extension is set) using a set screw in the end of the 115mm gauge stem. The cutting blade can be set for either right or left handed use. The opposite end of the stem is tapped to accept a 9.5mm diameter wheel cutter. The fence and the internal portion of the locking collet are a single eccentric brass turning. The 25mm diameter fence is eccentric to maximise rub depth. and also prevents the gauge from rolling off the workbench. Comes complete with a dozen spare blades, two hardened steel pins, a wheel cutter screw, hex key and instruction leaflet. Made in Canada.
