3M 7100405921 767F Cloth Belt 60 Plus Grit 6x48 Inches

Product Description

The 3M 7100405921 is a 767F cloth abrasive belt designed for high-removal grinding and finishing applications across metal, wood, and composite surfaces. Built on a Film-lok backing with a Single-flex construction, this belt is engineered to conform to contoured workpieces while maintaining consistent cut rate. The abrasive uses 3M Precision-Shaped Grain technology, which is engineered to cut faster and outlast conventional alumina zirconia belts. Each case contains 5 belts measuring 6 inches wide by 48 inches in overall length, rated at 60 Plus grit with a YF weight backing for durability under sustained pressure.

This belt is suited for metalworking, fabrication, and woodworking shops where production grinding demands both longevity and cut consistency. The 6 inch by 48 inch format fits a standard class of stationary belt grinders and wide-belt sanders commonly found in fabrication facilities, weld shops, and millwork operations. The 60 Plus grit designation places this belt in the medium-coarse range, making it appropriate for weld blending, stock removal, and surface preparation before finer finishing passes. Sold in cases of 5, it is structured for production use rather than single-task maintenance.

Key Features

• Precision-Shaped Grain construction cuts faster and lasts longer than conventional alumina zirconia abrasives
• Film-lok backing provides enhanced tear resistance and dimensional stability during high-pressure grinding
• Single-flex construction allows the belt to conform to curved and contoured workpieces
• 60 Plus grit rating suited for weld blending, stock removal, and surface prep
• YF weight backing delivers durability under sustained load
• Case quantity of 5 supports production-volume abrasive programs

Compatibility

Designed to fit stationary belt grinders and wide-belt sanding machines that accept a 6 inch by 48 inch abrasive belt format. Verify platen and contact wheel dimensions on the host machine before installation.

Installation Notes

Belt installation should be performed by the machine operator following the equipment manufacturer's belt-change procedure. Power down and lock out the grinder or sander before removing or mounting any abrasive belt. Confirm belt tracking adjustment before running at full speed, and inspect the belt for tears or edge damage prior to each use. Follow applicable ANSI and OSHA abrasive safety standards for belt grinding equipment.
