Our largest 4x48 attachment mated to our industrial 1HP motor make this machine a workhorse! The additional length and width of the 4x48 attachment provide loads of surface area. The extra long and extra wide precision top platen is for straightening, flat finishing, or profiling large pieces. Additionally the longer belt length offers increased belt wrap on the underside slack belt surface for external contouring and blending. The front contact wheel can be used for smooth controlled grinding, contouring, or internal finishing. The large 7 inch disc sander on the side offers plenty of surface area to work with for beveling, deburring, squaring and general sanding. The quick change belt system allows you to change from grinding to polishing in seconds. The belt attachment can operate in a horizontal or vertical position.
