3M 7000120411 Rubber Slotted Expander Wheel 1.5x1 in

Product Description

The 3M 7000120411 is a rubber slotted expander wheel designed to hold abrasive bands or belts during grinding and finishing operations. The slotted rubber drum expands outward through centrifugal force as the spindle spins, keeping the abrasive band firmly seated and preventing slippage under load. The wheel measures 1.5 inches in diameter and 1 inch wide, accepting bands or belts of the same dimensions. A 0.25 inch diameter shank fits standard 0.25 inch collet chucks and drill chucks, making it compatible with die grinders, rotary tools, and drill presses used in fabrication, metalworking, and surface prep work.

This expander wheel is suited for use in metalworking shops, fabrication facilities, and general maintenance environments where controlled material removal or surface finishing is required. It is typically used by machinists, pipefitters, welders, and maintenance technicians working on inside diameters, contoured surfaces, or deburring applications. The self-expanding design is especially useful in situations where consistent band tension is critical to finish quality and tool life.
