3M™, 7100023710, Mandrel, Regular, For Hole Size: 1/4 in, 1-1/2 to 2 in Wheel Diameter, 1/2 in Wheel Width, 1/4 in Shank, 2 in Overall Length, 20000 rpm Maximum

A small but mighty abrasive accessory, 3M™ unitized wheel mandrels secures Scotch-Brite™ unitized wheels (sold separately) to a rotary tool with a 1/4 in collet (such as a die grinder) for edge deburring and finishing. Crafted from steel, 3M™ unitized wheel mandrel also comes with two flanges that fit on either side of the wheel and a retainer nut that locks the wheel in place. Attach 3M™ unitized wheel mandrel to tools like 3M™ die grinders (sold separately). These power tools are designed for continuous use and have features that enhance operator comfort and control. For example, the precision balanced steel motor reduces vibration and weight, while 3M™ gripping material on the body enables a firm grip. To complete the system, combine the wheel and mandrel with 3M™ die grinders (sold separately). 3M™ die grinders feature 1/4 in collets, which provide quick and easy attachment of the mandrel/wheel assembly. In addition, 3M™ die grinders are designed for continuous use and have ergonomic features that enhance operator comfort and control. When this abrasive system, including the wheel, power tool and 3M™ unitized wheel mandrel, come together, you're one step closer to getting the job done.
