3M 7100000272 Rubber Slotted Expander Wheel 2x1 in

Product Description

The 3M 7100000272 is a rubber slotted expander wheel designed for use with 2-inch diameter by 1-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 against the workpiece during grinding and finishing operations. The 1/4-inch diameter shank fits standard 1/4-inch collet chucks and drill chucks, making it compatible with die grinders, rotary tools, and drill presses commonly used in fabrication, maintenance, and metalworking applications. Licensed tradespeople and shop technicians use this style of expander wheel for deburring, blending, and surface prep work on metal, composites, and similar materials.

This expander wheel is suited for bench-mounted or handheld rotary tool setups in both shop and field environments. It is a common tool in metal fabrication, welding shops, HVAC duct work finishing, and general maintenance trades where controlled abrasive action is needed in tight or contoured areas. The self-tensioning drum design reduces the need to stop and re-tension the abrasive band during use, which improves workflow consistency on repetitive grinding tasks.
