When it comes to jig making these UJK Technology Parf Anchor Dogs open a whole world of possibilities. CNC machined from 303 stainless steel, these dogs precisely match the holes made by the UJK Technology 20mm cutter. They fit with exacting precision into the 20mm holes of the UJK Technology Multifunction Workbench. They are compatible with the Festool MFT/3 tabletop and other grid tables with 20mm holes. The hole must be chamfered first which allows the chamfer profile of the dog to sit flush in the bench's top surface. Once installed into your workbench you have an M8 threaded hole in your work top for all number of applications. You can now easily make hold down clamps, plane stops and a host of jig making possibilities. The only limit to their uses is your imagination.-bg
