The Merit M-9-2.5 extra-shank-length mandrel securely mounts cartridge and spiral abrasive rolls, also called tapered cartridge rolls, onto a grinder that accepts a 1/4"-diameter shank. The mandrel has an extended shank and 4" overall length for hard-to-reach applications. It fits cartridges and spiral rolls with a 1/8"-diameter center. The one-piece mandrel body is made of steel for strength and extended tool life. The mandrel has an unthreaded end that accepts a roll and holds it in place with a cone-shaped segment, and it has a 1/4"-diameter shank that inserts into a grinder's chuck.
