3M 7100134240 Abrasive Belt 132x3 Inch P80 Grit Silicon Carbide

Product Description

The 3M 7100134240 is a silicon carbide coated abrasive belt designed for grinding, blending, deburring, and finishing on metal surfaces. Measuring 132 inches long and 3 inches wide, this belt carries a P80 grit rating and is built for use on backstand grinders in demanding shop environments. The abrasive mineral is bonded to a tough polyester cloth backing using a heat-resistant resin system, giving the belt durability under sustained pressure, heat, and moisture. Licensed HVAC, plumbing, and general metalworking shops rely on this belt for consistent stock removal and surface finishing across a range of metal substrates.

This belt is suited for wet or dry applications in fabrication, maintenance, and metal finishing settings. The silicon carbide mineral fractures cleanly during use, continuously exposing fresh cutting edges and maintaining a consistent scratch pattern throughout the belt life. Typical applications include deburring pipe ends, blending weld seams, and finishing stainless or carbon steel components on backstand or slack-belt grinding setups. It is well suited for trade shops handling HVAC ductwork, pipe fabrication, and general metal prep work.

Key Features

• Silicon carbide abrasive mineral cuts faster than aluminum oxide and fractures consistently for a uniform finish throughout belt life
• P80 grit rating provides aggressive stock removal while leaving a controlled surface finish
• Tough, water-resistant polyester cloth backing supports both wet and dry grinding and finishing without tearing or nicking
• Heat-resistant resin bond locks abrasive to backing for durability under pressure and elevated temperatures
• 132 inch length and 3 inch width sized for standard backstand grinder configurations
• Cloth construction provides flexibility for contouring and blending on irregular surfaces

Compatibility

Designed for use on backstand grinders and slack-belt finishing machines that accept a 132 inch by 3 inch abrasive belt.

Installation Notes

Belt installation and tensioning should follow the grinder manufacturer guidelines for tracking and tension adjustment. Ensure the machine is fully powered down and locked out before changing the belt. Inspect the contact wheel or platen for wear before mounting a new belt, as surface irregularities can cause premature belt failure. Eye protection and appropriate PPE should be worn during grinding and finishing operations.
