3M 7100122888 Abrasive Belt 60x37 in 120 Grit Aluminum Oxide

Product Description

The 3M 7100122888 is an aluminum oxide cloth-backed abrasive belt designed for general-purpose metalworking and woodworking applications. Measuring 60 inches in length and 37 inches in width with a 120 grit rating, this belt is built for heavy-duty stock removal and finishing on a wide range of substrates. The XF-weight polyester cloth backing resists tearing under high pressure, and the resin bond system holds up to elevated heat generated during aggressive grinding and sanding cycles. Licensed trades and shop technicians use this belt where consistent cut rate and long belt life are priorities.

This belt is suited for use on backstand and benchtop belt sanders, stroke sanders, portable belt grinders, and wide belt grinding and finishing machines. It performs reliably on mild steel, carbon steel, aluminum, bronze, and brass, making it a practical choice for metal deburring, weld blending, and general surface preparation. It also handles softer woodworking applications where a durable, consistent abrasive is needed across mixed-material workflows.

Installation Notes

Install on compatible belt sanding or grinding equipment rated for the belt dimensions before powering on the machine.
