3M 7100159585 Abrasive Belt 36 Grit 72x2 Inch Cloth

Product Description

The 3M 7100159585 is the Cubitrona II 981F abrasive cloth belt engineered for grinding, weld removal, finishing, and blending on softer metals. Built on a tough Y-weight polyester cloth backing, it uses 3M Precision-Shaped Grain to deliver fast, consistent stock removal. The belt incorporates an integrated dry lubricant and water-resistant polyester construction, allowing it to run with liquid coolants to prevent loading during extended use on aluminum, bronze, and brass. At 36 grit and measuring 72 inches in length by 2 inches in width, it suits high-material-removal tasks where heat control and grain life are priorities.

This belt is intended for metalworking operations in fabrication shops, welding environments, and manufacturing settings. Typical applications include deburring, weld seam removal, and surface blending on aluminum, brass, and bronze workpieces. The water-resistant backing makes it especially useful in wet-grinding setups where coolant is applied to manage heat buildup and extend abrasive life. It is commonly used with stationary belt grinders and wide-stroke sanders in light industrial and job-shop environments.

Key Features

• 3M Precision-Shaped Grain delivers fast cutting action on soft metals including aluminum, brass, and bronze
• Integrated dry lubricant reduces loading during prolonged soft-metal grinding
• Y-weight polyester cloth backing withstands aggressive grinding and edge-of-belt use
• Water-resistant material supports use with liquid coolants to control grinding temperatures
• Durable resin bond resists heat deterioration, extending abrasive service life
• Strong mineral adhesion minimizes shelling at belt edges during high-pressure passes

Compatibility

Designed as an OEM-style replacement abrasive belt for stationary belt grinders and wide-stroke sanders that accept 72-inch by 2-inch cloth belts. Best suited for use on aluminum, brass, and bronze substrates.

Installation Notes

Install and replace abrasive belts with the grinder or sander fully powered off and locked out per applicable OSHA lockout/tagout procedures. Verify belt tracking and tension before resuming operation, following the equipment manufacturer guidelines. Wear appropriate PPE including eye protection and gloves when handling and mounting abrasive belts. Inspect the belt for tears or damage prior to each use and do not exceed the maximum operating speed rated for the belt and machine combination.
