3M 7100009224 Forked Spindle Mandrel 3in X 0.25in

Product Description

The 3M 7100009224 is a forked spindle mandrel designed to hold and drive abrasive accessories on rotary power tools. The forked spindle design secures compatible abrasive pads, discs, or wheels and transfers rotation from a power tool chuck to the abrasive surface. This mandrel measures 3 inches in length with a 1/4-inch shank diameter, making it compatible with standard rotary tool chucks. It is a replacement-style accessory used in surface preparation, blending, finishing, and deburring applications across industrial, mechanical, and fabrication environments.

This mandrel is suited for use with bench-mounted or handheld rotary tools in industrial maintenance, metalworking, and fabrication shops. Technicians and tradespeople reach for this type of mandrel when mounting 3M abrasive accessories for surface conditioning tasks on metal, composites, or similar substrates. The 1/4-inch shank fits most standard rotary tool chucks and die grinder collets commonly found in shop and field environments.
