3M 7100039436 Coated Abrasive Belt P320 103x50 Inch

Product Description

The 3M 7100039436 is a coated abrasive cloth belt designed for grinding, blending, deburring, and finishing operations on metal surfaces. Built on a tough polyester backing with heat-resistant resin bonding, it delivers consistent material removal across a wide range of metal types, including stainless steel. At 103 inches long and 50 inches wide, this belt fits wide-format backstand and centerless grinding setups. The aluminum oxide abrasive grain cuts aggressively at P320 grit, making it well-suited for fine finishing and surface conditioning work where heat buildup and belt wear are common concerns. Suitable for both wet and dry applications.

This belt is used in industrial and fabrication environments where stainless steel coil finishing, sheet grinding, and continuous-feed centerless operations are performed. The combination of polyester backing and heat-resistant resin construction handles medium-pressure applications without premature breakdown. Metalworking shops, fabrication facilities, and finishing lines handling stainless and other alloy metals are the primary installation environments for this belt size and grit combination.

Key Features

• Aluminum oxide abrasive grain provides fast cutting and consistent performance on ferrous and non-ferrous metals
• Tough polyester backing maintains dimensional stability under medium-pressure grinding conditions
• Heat-resistant resin bond secures abrasive grains during high-heat, high-pressure, and wet operations
• P320 grit rating suited for fine finishing, blending, and deburring on stainless steel and other metals
• Compatible with wet and dry grinding and finishing applications
• Sized for wide-format backstand and centerless grinding equipment

Compatibility

Designed for use in backstand, centerless, and coil finishing applications on stainless steel, carbon steel, and other metal surfaces requiring grinding, blending, deburring, or finishing at P320 grit.

Installation Notes

Belt installation should be performed by qualified metalworking or maintenance personnel with the grinding machine de-energized and locked out before mounting. Verify belt tracking and tension according to the equipment manufacturer's specifications before resuming operation. Inspect the belt for tears or edge damage prior to each use, and never exceed the maximum speed rating of the machine or belt.
