3M 7100050305 Cubitron Ii 947A Abrasive Belt 15.5x3.5 in

Product Description

The 3M 7100050305 is a Cubitron II 947A coated abrasive belt designed for high-efficiency grinding and finishing on metal workpieces. It uses 3M Precision-Shaped Grain technology, which slices through material rather than gouging or plowing, resulting in faster stock removal and cooler cutting temperatures compared to conventional ceramic abrasive belts. The belt measures 15.5 inches in length by 3.5 inches in width and features an X-weight poly-cotton backing engineered for flexibility during contouring and blending operations. A built-in grinding aid reduces friction and further lowers heat generation at the contact zone. This belt is sold individually and is suited for low to medium pressure grinding applications performed by metalworkers, fabricators, and maintenance technicians.

This belt is optimized for use on stainless steel, mild steels, and aluminum in fabrication shops, maintenance facilities, and light manufacturing environments. Its flexible X-weight backing makes it well suited for surface blending, weld removal, and finishing passes where consistent contact with the workpiece is required. The cooler cutting action reduces the risk of heat discoloration and metallurgical damage, which is especially important when working with stainless steel and aluminum. It is designed for use on standard belt grinders and backstand finishing machines running appropriate belt speeds for metal applications.

Key Features

• Precision-Shaped Grain slices through metal rather than gouging, improving cut rate and reducing heat
• Grinding aid included to lower friction and keep cutting temperatures cool
• X-weight poly-cotton backing provides flexibility for contouring and blending
• Optimized for low and medium pressure applications on stainless steel, mild steels, and aluminum
• Designed to last significantly longer than conventional ceramic abrasive belts
• Sold individually; minimum order quantity is 50 units per order

Compatibility

Designed for use on standard belt grinders and backstand finishing machines compatible with 15.5 x 3.5 inch abrasive belts. Suitable for grinding and finishing stainless steel, mild steel, and aluminum workpieces at low to medium contact pressures.

Installation Notes

Installation and belt changes should be performed by a qualified operator following the machine manufacturer's guidelines. Ensure the grinder or backstand is fully powered off and any pneumatic pressure is relieved before changing the belt. Verify belt tracking and tension before resuming operation. Always wear appropriate PPE including eye protection and gloves when handling abrasive belts and operating grinding equipment.
