Make the Most of Your Scotch Brite™ Unitized Wheels

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.
