3M 7000118855 Aluminum Oxide Cloth Belt 50 Grit 21x3 in

Product Description

The 3M 7000118855 is an aluminum oxide cloth sanding belt designed for metal deburring, general metalworking, and woodworking applications. Built on an X-weight cloth backing, this belt handles heavy sanding and grinding without breaking down under pressure or heat. The resin bond holds the abrasive firmly through demanding cycles, and the 50-grit aluminum oxide mineral cuts aggressively across metal and wood substrates. At 21 inches long and 3 inches wide, it fits wide belt, edge, and portable belt sanding equipment. Licensed HVAC, plumbing, and mechanical contractors reach for this belt when preparing pipe ends, deburring cut stock, and smoothing weld seads before assembly.

This belt is suited to both metal and wood surfaces in residential and light commercial shop environments. The tube-shaped band profile fits inner and outer contours, making it effective for removing parting lines, casting imperfections, and burrs from machined or cast metal parts. It also fits onto a rubber expander wheel attachment for use with a die grinder or rotary drill, extending its reach to tight or curved surfaces that flat-platen setups cannot access.

Installation Notes

Ensure the sanding machine or die grinder is fully powered off and unplugged before mounting or removing the belt.
