The Multitool grinder attachments are among the most popular and well-known grinder attachments on the market. Multitool Attachments extend your capabilities far beyond traditional bench grinders. The front contact wheel can be used for smooth controlled grinding, contouring, or internal finishing. The precision top platen can be used for perfect flat finishing. The underside offers a slack belt surface for external contouring and blending. The large 7-inch disc sander on the side offers plenty of surface area to work with for beveling, deburring, squaring, and general sanding. Multitool Attachments will fit any bench grinder with a 1/2 or 5/8 shaft.
