3M 7100162631 Abrasive Belt 36 Grit 132x3 Inch Cloth

Product Description

The 3M 7100162631 is the Cubitrona II 981F abrasive cloth belt, engineered for grinding, weld removal, finishing, and blending on softer metals including aluminum, bronze, and brass. Built on a tough Y-weight polyester cloth backing, it uses 3M Precision-Shaped Grain for fast, aggressive stock removal. The belt measures 132 inches long by 3 inches wide and is rated at 36 grit, making it well-suited for heavy-duty material removal and initial finishing passes. Licensed metalworking technicians and fabrication shop operators are the primary installers and users of this belt in stationary and portable belt grinder applications.

This belt is designed for use on soft metal substrates where loading is a persistent problem. The integrated dry lubricant and water-resistant polyester construction allow operation with liquid coolants, reducing heat buildup and preventing clogging when working aluminum, brass, and bronze. It performs in fabrication shops, welding operations, and metal service centers where consistent cut rate and belt longevity are critical. The 36-grit designation targets aggressive grinding and weld seam removal rather than final finishing passes.

Key Features

• 3M Precision-Shaped Grain delivers fast cut rates on soft metal substrates

Compatibility

Designed for use on stationary and portable belt grinders that accept a 132-inch by 3-inch abrasive belt. Best suited for soft metal applications including aluminum, brass, and bronze workpieces.

Installation Notes

Install on a belt grinder with the correct platen size and tracking adjustment for a 132-inch by 3-inch belt. Confirm the machine is fully de-energized and the tension released before mounting or removing the belt. Inspect the belt for tears or edge damage before each use, and never operate a damaged or improperly tracked belt. When using liquid coolants, verify the grinder and workstation are rated for wet grinding operations.
