3M 7100205951 Abrasive Belt P320 Grit 30x1 Inch Ao Cloth

Product Description

The 3M 7100205951 is a 302D-series aluminum oxide abrasive belt built for metalworking professionals who need consistent finishing performance across a range of metals. The belt measures 30 inches in length and 1 inch in width, features a P320 grit rating, and uses an open coat construction bonded to a flexible J-weight cloth backing. That backing conforms readily to contours and complex part geometries, making this belt a reliable choice for light grinding, finishing, deburring, and grain-setting on both ferrous and non-ferrous metals.

This belt is designed for dry metalworking applications on carbon steel, stainless steel, aluminum, brass, bronze, and copper. It mounts on backstand grinders, file belt tools, and benchtop motors. The open coat layout evacuates sanding dust efficiently, maintaining an aggressive cut rate and extending abrasive service life across production and shop finishing tasks. Fabricators, welders, and metal finishing technicians are the primary installers and end users.

Key Features

• Aluminum oxide abrasive cuts fast and performs consistently across most common metals
• P320 grit rating suited for finishing, deburring, and setting the grain
• Open coat construction evacuates dust for a more aggressive cut and longer belt life
• Flexible J-weight cloth backing conforms to contours and complex part profiles
• Resin bond maximizes abrasive adhesion and extends usable life
• Compatible with backstand grinders, file belt tools, and benchtop motors

Compatibility

Designed for use on backstand grinders, file belt tools, and benchtop motors in dry metalworking applications involving carbon steel, stainless steel, aluminum, brass, bronze, and copper.

Installation Notes

Belt installation should be performed by qualified personnel with the grinder or motor powered down and unplugged before mounting. Verify belt tracking and tension per the tool manufacturer's guidelines before resuming operation. Inspect the belt for tears or separation before each use, and do not exceed the maximum operating speed rated for the tool and belt combination.
