The MR4 takes mortising on the WoodRat to new levels of speed, accuracy and versatility.

A precision engineered, aluminium trough holds multiple pieces, solid and square - ready to be cut in any way you wish. Accurate, repeatable mortices are now a easier than ever. And (being WoodRat) there's more. . .
