3M 7010359470 Diamond Polishing Cloth Belt 25 X 3 in

Product Description

The 3M 7010359470 is a diamond polishing cloth belt designed for polishing and finishing hard materials rated above 62 on the Rockwell C scale. Built around micron-graded diamond mineral and a long-lasting resin bond, it delivers fine surface finishes on materials that conventional abrasives cannot handle. The water-resistant X-weight cloth backing provides durability and flexibility during high-demand finishing operations. This belt is intended for use with coolant and is suited for metalworking, toolroom, and precision grinding applications where surface finish quality is critical.

This belt is used in industrial and metalworking environments where hard-to-grind materials require controlled material removal and consistent surface quality. Typical applications include finishing carbide, ceramics, hardened steel, and other superhard substrates. It serves as a direct alternative to conventional superfinishing techniques, making it appropriate for tool and die shops, precision manufacturing, and maintenance operations requiring tight surface finish tolerances.

Key Features

• Micron-graded diamond mineral for fine, controlled surface finishes
• Long-lasting resin bond extends belt service life under continuous use
• Water-resistant X-weight cloth backing provides durability and flexibility
• Engineered for materials rated above 62 on the Rockwell C scale
• Must be run with coolant to maintain performance and belt integrity
• Serves as an alternative to conventional superfinishing techniques

Compatibility

Designed for polishing and finishing operations on hard-to-grind materials including carbide, ceramics, and hardened substrates requiring a superfinishing-grade abrasive belt.

Installation Notes

Installation should be performed by a qualified toolroom technician or machine operator familiar with abrasive belt equipment. Ensure the machine is fully powered down and locked out before mounting or changing belts. This belt must be run with coolant at all times to prevent heat buildup and premature wear. Verify belt tracking and tension according to equipment manufacturer guidelines before resuming operation.
