3M 7100032501 Abrasive Belt 36 Grit 21x3 Inch Aluminum Oxide

Product Description

The 3M 7100032501 is an aluminum oxide coated abrasive cloth belt designed for metal deburring, general metalworking, and woodworking applications. Built on an X-weight cloth backing, this 341D series belt handles heavy sanding and grinding demands without breaking down under high heat or pressure. The resin bond holds the 36-grit abrasive mineral firmly in place, delivering fast material removal across a range of metal and wood substrates. It measures 21 inches in length and 3 inches in width. Tradespeople and shop technicians working with die grinders, rotary drills, or belt sanders are the primary users.

This belt is suited for wide belt, edge, and portable belt sanding setups in both metalworking and woodworking environments. The tube-shaped band design fits inner and outer contours, making it effective for removing parting lines, surface imperfections, and burrs from metal parts. It is compatible with rubber expander wheel attachments used on die grinders and rotary drills, expanding its utility across bench and handheld sanding applications in fabrication, maintenance, and finishing work.
