3M 7010361843 Cubitron Ii 947A Abrasive Belt 40 Grit

Product Description

The 3M 7010361843 is a coated abrasive belt from the Cubitron II 947A line, built for aggressive material removal on metal surfaces. It uses 3M Precision-Shaped Grain technology, which slices through metal rather than gouging or plowing, resulting in faster cuts, lower operating temperatures, and a longer belt life compared to conventional ceramic abrasive belts. The X-weight poly-cotton backing delivers the flexibility needed for contour work and low-to-medium pressure applications. At 40 grit, this belt is suited for stock removal and blending passes where aggressive cutting action is the priority.

This belt is designed for use on stainless steel, mild steels, and aluminum in fabrication, weld blending, and general metalworking applications. The 18 inch length and 1/2 inch width fit a range of portable and stationary belt grinders used in light industrial and shop environments. The included grinding aid reduces friction at the contact point, which helps protect heat-sensitive workpieces from discoloration or metallurgical damage during extended grinding sessions.

Key Features

• Precision-Shaped Grain cuts metal faster and cooler than conventional ceramic abrasives
• Grinding aid reduces friction and lowers heat generation at the workpiece surface
• X-weight poly-cotton backing provides flexibility for contour and low-to-medium pressure use
• 40 grit construction suited for aggressive stock removal on metal
• Extended belt life reduces change-out frequency in high-use shop environments
• Optimized for stainless steel, mild steel, and aluminum substrates

Compatibility

Designed for use on portable and stationary belt grinders accepting 18 inch by 1/2 inch abrasive belts, with optimal performance on stainless steel, mild steel, and aluminum workpieces in low to medium pressure grinding applications.

Installation Notes

Belt installation should be performed by a qualified operator following the grinder manufacturer's instructions and applicable ANSI safety standards for abrasive products. Ensure the grinder is fully de-energized and unplugged before changing the belt. Verify belt tracking and tension before resuming operation. Always wear appropriate PPE including eye protection and gloves when handling and operating abrasive belts.
