Granite Surface Plate 6" x 18" x 2" A Grade

Usually only found in machine shops, the super flat face of the granite surface plate is ideal for leveling small plane beds, flattening waterstones and general sharpening duties. Simply soak a piece of wet/dry sandpaper in water and lay it down on the stone; the capillary action of the water adheres the paper to the stone, eliminating the need for spray adhesives or PSA sandpaper. When done, wipe clean with a paper towel. This A grade plate measures 6" x 18" x 2", weighs 26 lbs. and comes with a surface map. Plate does not have ledges.
