3M 7010299911 Cubitron Ii 947A Abrasive Belt 120 Grit

Product Description

The 3M 7010299911 is the Cubitron II 947A coated abrasive belt, built around 3M Precision-Shaped Grain technology. Unlike conventional ceramic abrasive grains that gouge or plow through material, the triangular shaped grains in the 947A slice through metal with a shearing action, cutting faster and generating less heat in the process. The belt runs at 120 grit and features an X-weight poly-cotton backing engineered for flexibility under load. It weighs 0.62 pounds per unit and is sized at 48 inches long by 6 inches wide. A built-in grinding aid reduces friction further, extending belt life and protecting workpieces from heat-related discoloration or warping.

This belt is optimized for low- to medium-pressure grinding and finishing applications on stainless steel, mild steel, and aluminum. It is well suited for fabrication shops, weld blending, deburring, and surface conditioning work where heat buildup is a concern. The flexible poly-cotton backing conforms to slightly contoured surfaces, making it useful on a range of contact-wheel and platen configurations. Metal fabricators, maintenance technicians, and industrial finishing pros are the primary installers of this consumable.

Key Features

• Precision-Shaped Grain slices metal rather than gouging, delivering faster stock removal with less pressure
• Grinding aid included to reduce friction and keep cutting temperatures low
• Cool cutting action reduces risk of heat damage, discoloration, or warping on the workpiece
• X-weight poly-cotton backing provides flexibility for contoured and flat surface applications
• Rated for use on stainless steel, mild steel, and aluminum
• Extended belt life compared to conventional ceramic abrasive belts

Compatibility

Designed for use on standard belt grinders and finishing machines accepting a 48-inch by 6-inch abrasive belt. Suitable for low- and medium-pressure grinding applications on stainless steel, mild steel, and aluminum workpieces.

Installation Notes

Installation of abrasive belts should be performed by a qualified operator following machine manufacturer guidelines. Ensure the grinder is fully powered down and locked out before changing belts. Verify belt tracking and tension per equipment specifications before resuming operation. Always wear appropriate PPE, including eye protection and gloves, when handling and operating abrasive belts.
