3M 302D-P220-J2 Cloth Abrasive Sanding Belt P220 Grit J-Weight Aluminum Oxide

The 3M Cloth Belt 302D is a high-performance aluminum oxide abrasive sanding belt featuring open coat construction and a flexible J-weight cloth backing. Engineered for demanding metalworking applications, it delivers fast cutting action and long-lasting durability on a wide variety of ferrous and non-ferrous metals.

This belt is ideal for light grinding, finishing, deburring, and grain-setting on carbon steel and stainless steel, as well as soft metals such as aluminum, brass, bronze, and copper. The P220 very fine grit makes it well-suited for finishing and blending work.

Key Features:

• Aluminum oxide abrasive — cuts fast and performs reliably across most metals
• Open coat construction — channels sanding swarf and dust away from the belt surface for a more aggressive cut and extended belt life
• Flexible J-weight cloth backing — conforms to contours and complex part geometries for consistent, uniform finishes
• Resin bond — fuses abrasive to backing to withstand high heat and pressure, maximizing abrasive life
• Film-lok splice — provides a strong, low-profile splice for smooth belt operation
• Full-flex — enhanced flexibility for blending, radiusing, and fine finishing on irregular surfaces
• Compatible with backstand grinders, file belt tools, and benchtop motors
• Suitable for dry metalworking applications
• Made in the USA

The 3M 302D series abrasive belt is a trusted choice in metal fabrication, plumbing fixture finishing, builders hardware, and precision metalworking industries where consistent surface quality is critical.
