3M 7100139895 Abrasive Belt 947A 80 Grit 24x0.5 Inch

Product Description

The 3M 7100139895 is the Cubitron II 947A coated abrasive belt, engineered for aggressive material removal on metal surfaces. Built with 3M Precision-Shaped Grain, the belt slices through workpiece material rather than gouging or plowing, delivering faster cuts at lower applied pressure and generating less heat than conventional ceramic abrasive belts. The X-weight poly-cotton backing provides the flexibility needed for contour and flat grinding applications. At 80 grit, this belt is suited for aggressive stock removal while keeping surface temperatures manageable. It is designed for use by fabricators, welders, and metalworkers who require consistent performance across extended production runs.

This belt is optimized for low and medium pressure grinding and finishing applications on stainless steel, mild steel, and aluminum. The 24 inch length and 1/2 inch width fit standard narrow-belt grinders and file belt tools commonly found in metal fabrication and maintenance shops. A built-in grinding aid reduces friction during contact, further limiting heat buildup and reducing the risk of heat-related discoloration or warping on finished workpieces.

Key Features

• Precision-Shaped Grain cuts metal with a slicing action, removing material faster with less applied pressure
• Built-in grinding aid reduces friction and keeps cutting temperatures lower
• X-weight poly-cotton backing delivers flexibility for contoured and flat surface work
• Cool cutting action reduces risk of heat damage to the workpiece
• Lasts up to 4 times longer than conventional ceramic abrasive belts
• Optimized for low and medium pressure applications on stainless steel, mild steel, and aluminum

Compatibility

Designed for use on narrow-belt grinders and file belt machines that accept a 24 inch by 1/2 inch abrasive belt, typically used in metal fabrication, maintenance, and welding finishing applications.

Installation Notes

Installation of abrasive belts should be performed by qualified personnel following the grinder or file belt tool manufacturer's instructions. Ensure the machine is fully powered down and disconnected from its power source before changing belts. Verify belt tension and tracking per the tool manufacturer's specifications before resuming operation. Always use appropriate PPE, including eye protection and gloves, when handling and installing abrasive belts.
