3M 7000120412 Rubber Slotted Expander Wheel 2x2 in

Product Description

The 3M 7000120412 is a slotted rubber expander wheel designed for use with 2-inch diameter by 2-inch wide abrasive bands or belts. The slotted rubber drum expands outward with centrifugal force as the wheel spins, keeping the abrasive band seated firmly during grinding and deburring operations. The 1/4-inch diameter shank fits standard 1/4-inch collet chucks and drill chucks, making it compatible with a range of rotary tools and die grinders. This wheel is suited for metalworking, fabrication, and finishing applications where consistent abrasive contact is required.

This expander wheel is used in applications requiring controlled material removal on metal, wood, or composite surfaces. It is typically mounted in a die grinder or drill press for grinding, blending, and finishing work in fabrication shops, maintenance environments, and light industrial settings. The centrifugal expansion mechanism eliminates the need for manual band tensioning during operation.
