A small but mighty abrasive accessory, 3M™ Unitized Wheel Mandrels secures Scotch-Brite™ Unitized Wheels (sold separately) to a rotary tool with a ¼” 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

Available in a range of lengths for attachment to ¼" collet

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.

Complete Abrasive System Solutions
To complete the system, combine the wheel and mandrel with 3M™ Die Grinders (sold separately). 3M™ Die Grinders feature ¼" 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.
