3M 7100087886 Diamond Polishing Cloth Belt

Product Description

The 3M 7100087886 is a micron-graded diamond polishing cloth belt designed for precision finishing and polishing of extremely hard materials. Built around a water-resistant X-weight cloth backing and a durable resin bond, this belt delivers consistent stock removal and fine surface finishes on materials rated harder than 62 on the Rockwell C scale. The diamond abrasive mineral is micron-graded for controlled, repeatable results across finishing and superfinishing operations. This belt is intended for use with coolant to maximize performance and extend belt life. It is sized at 18 15/16 inches long by 1 1/2 inches wide.

This belt is suited for industrial and trade applications involving grinding, lapping, and finishing of hard-to-grind materials such as carbide, ceramics, hardened steel, and similar substrates. It is commonly used in tool and die shops, precision machining environments, and metalworking applications where conventional abrasive belts fall short. The 652WY is engineered as a direct alternative to conventional superfinishing techniques, offering a more efficient path to fine surface finishes on hardened workpieces. Machinists, tool grinders, and precision finishing technicians are the primary users.

Key Features

• Micron-graded diamond mineral provides controlled, fine surface finishes
• Durable resin bond for long-lasting abrasive performance
• Water-resistant X-weight cloth backing for stability and flexibility
• Engineered for materials harder than 62 Rockwell C scale
• Designed to run with coolant for optimal results and belt longevity
• Serves as a direct alternative to conventional superfinishing techniques

Compatibility

Designed for use on belt grinding and finishing machines that accept an 18 15/16 inch by 1 1/2 inch abrasive belt. Suitable for polishing and finishing operations on materials rated harder than 62 on the Rockwell C scale, including carbide, ceramics, and hardened steels where diamond abrasive is required.

Installation Notes

Installation should be performed by a qualified machinist or abrasive equipment technician. Ensure the belt grinder or finishing machine is fully powered down and locked out before mounting or replacing the belt. Always run this belt with an appropriate coolant to prevent overheating and premature wear. Verify belt tension and tracking per the equipment manufacturer's guidelines before initiating operation.
