3M 7100199087 Abrasive Belt 40 Grit 72x1 Inch Cloth

Product Description

The 3M 7100199087 is a Cubitron II 947A abrasive belt engineered for high-efficiency grinding and finishing on metal surfaces. Built with 3M Precision-Shaped Grain technology, the belt slices through material rather than gouging or plowing, which translates to faster stock removal at lower applied pressure. The X-weight poly-cotton cloth backing provides the flexibility needed for contoured or flat surface work. At 40 grit, this belt is suited for aggressive material removal while the integrated grinding aid reduces friction and keeps the cut cooler than conventional ceramic abrasive belts.

This belt is optimized for low to medium pressure applications on stainless steel, mild steels, and aluminum. The 72-inch length by 1-inch width configuration fits a range of stationary and portable belt grinders commonly used in fabrication shops, weld prep operations, and metal finishing lines. Metalworkers, fabricators, and maintenance technicians handling structural steel or tube work will find this belt a direct fit for high-cycle grinding tasks where heat buildup and premature belt wear are common concerns.

Key Features

• Precision-Shaped Grain slices metal for faster removal with less applied pressure
• Integrated grinding aid reduces friction and lowers cutting temperature
• Cool cutting action reduces risk of heat discoloration or workpiece distortion
• X-weight poly-cotton backing delivers flexibility for contoured and flat surfaces
• Rated for up to 4 times longer service life compared to conventional ceramic belts
• Suitable for stainless steel, mild steel, and aluminum

Compatibility

Designed for use on belt grinders and finishing machines that accept a 72-inch by 1-inch abrasive belt; optimized for low to medium pressure grinding applications on stainless steel, mild steels, and aluminum.

Installation Notes

Belt installation and replacement should be performed by qualified personnel following the machine manufacturer's guidelines. Ensure the grinder is fully powered down and locked out before changing the belt. Verify belt tracking alignment after installation and before resuming operation. Always wear appropriate PPE including eye protection and gloves when handling abrasive belts.
