3M 7100023487 Cubitron Ii 947A Abrasive Belt 80 Grit

Product Description

The 3M 7100023487 is the Cubitron II 947A coated abrasive belt, built for high-performance metal grinding and finishing. At 132 inches long and 3 inches wide, this belt uses 3M Precision-Shaped Grain technology, which slices through metal rather than gouging it. That grain geometry removes material faster at lower contact pressure and generates less heat than conventional ceramic abrasive belts. The X-weight poly-cotton backing delivers the flexibility needed for contour work and low-to-medium pressure applications. It is well suited for metal fabrication shops, weld blending, and surface conditioning work where heat control and cut rate both matter.

This belt is optimized for low and medium pressure grinding and finishing on stainless steel, mild steel, and aluminum. Typical applications include weld seam removal, surface stock removal, and pre-finishing passes on fabricated metal components. The 80-grit designation makes it a productive choice for aggressive material removal before transitioning to finer finishing stages. Shops running high-volume metal fabrication or maintenance work will find the extended belt life and cooler cut reduce changeover frequency and rework risk.

Key Features

• Precision-Shaped Grain slices metal rather than plowing, producing faster stock removal with less applied pressure
• Integrated grinding aid reduces friction and keeps cutting temperatures lower to protect the workpiece
• Cool cutting action reduces risk of heat discoloration, warping, or metallurgical damage on finished surfaces
• X-weight poly-cotton backing provides flexibility for contoured surfaces and low-to-medium pressure work
• Extended service life compared to conventional ceramic abrasive belts, reducing belt change frequency
• 80-grit rating suited for aggressive stock removal on stainless steel, mild steel, and aluminum

Compatibility

Designed for use on standard belt grinders and abrasive belt finishing machines accepting a 132-inch by 3-inch belt. Optimized for low and medium pressure applications on stainless steel, mild steel, and aluminum workpieces.

Installation Notes

Belt installation and tracking adjustment should be performed with the machine powered down and locked out per OSHA lockout/tagout procedures. Verify that the machine's contact wheel and platen are sized for a 3-inch wide belt before mounting. Confirm belt tracking is centered before returning the machine to operation. Always wear appropriate PPE including eye protection and gloves when handling abrasive belts and operating grinding equipment.
