This tool rest is designed for mounting directly to the bench in front of either a 150mm(6") or 200mm(8") bench grinder. In the face of the rest there is a slot into which the optional grinding jig (M0601) slides. The toolrest and the grinding jig can be bought as separate items or, if preferred, as a pair with a useful cost saving. As always with Veritas products this tool rest is well thought-out and immaculately produced, and should prove to be of great use to the turner or general woodworker.
