3M 7100207239 Abrasive Cloth Belt P400 48x6 Inch Ao

Product Description

The 3M 7100207239 is a 361F series aluminum oxide abrasive cloth belt designed for grinding, blending, deburring, and finishing operations on metal surfaces. At P400 grit, it delivers fine finishing cuts suited to production environments where surface quality matters. The belt measures 48 inches in length and 6 inches in width, with a tough polyester cloth backing and a heat-resistant resin bond that holds the abrasive under sustained pressure, heat, and moisture. It is used by metal fabricators, maintenance machinists, and finishing technicians working on steel, stainless steel, and similar hard metals.

This belt is built for coil and sheet finishing lines where flexibility and durability are both required. The polyester backing maintains consistent contact pressure across medium-load applications, and the resin bond resists breakdown under wet or dry conditions. It is well suited to centerless grinding setups, backstand grinders, and wide-belt finishing machines. Stainless steel coil finishing is a primary application, where surface consistency across long runs is critical.

Key Features

• P400 grit aluminum oxide abrasive for fine metal finishing and blending
• Polyester cloth backing for flexibility and durability in medium-pressure applications
• Heat-resistant resin bond holds abrasive under pressure, heat, and moisture
• Rated for both wet and dry use
• Suited for centerless, backstand, and wide-belt machine configurations

Compatibility

Designed for use in centerless grinding, backstand, and wide-belt finishing machine applications on metal substrates including stainless steel and carbon steel coils and sheets.

Installation Notes

Belt installation should be performed by a qualified machine operator or maintenance technician following the grinder or finishing machine manufacturer's belt-change procedure. Ensure the machine is fully de-energized and locked out before changing belts. Verify belt tracking and tension per equipment specifications before resuming operation. Inspect the belt for cracks or edge damage before each use.
