3M 7100023486 Abrasive Belt 120 Grit 132x3 Inch

Product Description

The 3M 7100023486 is a Cubitron II 947A coated abrasive belt built for high-throughput metal grinding and finishing. It uses 3M Precision-Shaped Grain technology, which slices through metal rather than gouging or plowing, resulting in faster material removal at lower applied pressure. The belt measures 132 inches long by 3 inches wide and runs at 120 grit. An X-weight poly-cotton backing provides flexibility suited to contoured or flat workpiece surfaces. A built-in grinding aid reduces friction and keeps cutting temperatures low, which helps prevent heat-related discoloration or warping on the workpiece.

This belt is designed for low to medium pressure grinding and finishing applications on stainless steel, mild steel, and aluminum. It is well suited to fabrication shops, maintenance operations, and production grinding environments where consistent cut rate and belt life are priorities. Typical uses include weld blending, surface preparation, and stock removal on flat or slightly contoured metal parts. The 132-inch length fits wide belt grinders and stroke sanders common in metal fabrication settings.

Key Features

• Precision-Shaped Grain slices metal rather than gouging, delivering faster cut rates with less pressure
• Built-in grinding aid reduces friction and lowers cutting heat to protect the workpiece
• X-weight poly-cotton backing optimized for flexibility on contoured and flat surfaces
• 120 grit delivers a balance of material removal rate and surface finish quality
• Designed for extended belt life compared to conventional ceramic abrasive belts
• Optimized for low and medium pressure applications on stainless steel, mild steel, and aluminum

Compatibility

Designed as a direct-fit coated abrasive belt for wide belt grinders and stroke sanders accepting a 132-inch by 3-inch belt configuration.

Installation Notes

Belt installation and replacement should be performed by qualified personnel following the grinder or sander manufacturer guidelines. Power down and lock out the machine before changing belts. Verify belt tracking and tension per machine specifications before resuming operation. Inspect the contact wheel and platen for wear before installing a new belt.
