3M 7100159553 Abrasive Belt 36 Grit 48x2 Inch Cloth

Product Description

The 3M 7100159553 is the Cubitrona II 981F abrasive sanding belt, engineered for grinding, weld removal, finishing, and blending on softer metals including aluminum, brass, and bronze. Built on a tough Y-weight polyester cloth backing, this belt uses 3M Precision-Shaped Grain to deliver fast, consistent stock removal. The water-resistant construction allows use with liquid coolants to manage heat and prevent loading during extended grinding operations. An integrated dry lubricant further reduces clogging when working softer metal substrates. Licensed HVAC, metalworking, and fabrication professionals rely on this belt for clean, controlled material removal.

This belt is sized at 48 inches long by 2 inches wide with a 36-grit designation, making it well suited for aggressive material removal and initial-pass grinding on soft metal components. Typical applications include weld blending on aluminum fabrications, surface finishing on brass fittings and bronze castings, and prep work before final finishing passes. The Y-weight backing handles both flat and edge grinding without delaminating under sustained pressure. It is commonly used on stationary belt grinders and inline grinding machines found in fabrication shops, HVAC equipment manufacturing, and plumbing component finishing lines.

Key Features

• 3M Precision-Shaped Grain delivers fast cutting on aluminum, brass, and bronze surfaces
• Integrated dry lubricant reduces loading and extends usable belt life on soft metals
• Tough Y-weight polyester cloth backing resists tearing under aggressive grinding pressure
• Water-resistant material supports use with liquid coolants to control grinding temperatures
• Durable resin bond resists heat-induced deterioration, maintaining grain adhesion longer
• Strong mineral adhesion reduces shelling when grinding along the belt edge

Compatibility

Designed for use on soft metal substrates including aluminum, brass, and bronze. Suitable for stationary belt grinders and inline grinding equipment that accept 48-inch by 2-inch abrasive belts.

Installation Notes

Installed by fabricators, metalworkers, and trade professionals on compatible belt grinding machines. Before changing belts, power down and lock out the grinder per OSHA lockout/tagout procedures. Verify belt tracking and tension are set per the machine manufacturer specifications before starting. When using liquid coolants, confirm the coolant is compatible with the workpiece material and the grinding machine.
