3M 7010325340 Diamond Polishing Cloth Belt 18.93x2.5 in

Product Description

The 3M 7010325340 is a diamond polishing cloth belt designed for precision polishing and finishing of extremely hard materials. Built on an X-weight water-resistant cloth backing, it uses micron-graded diamond mineral held in a durable resin bond to achieve fine surface finishes on materials rated harder than 62 on the Rockwell C scale. The belt measures 18.93 inches in length and 2.5 inches in width. It is intended for professional grinding and finishing operations where conventional abrasive belts fall short on hardness or surface finish requirements.

This belt is suited for industrial and trade finishing applications involving hard-to-grind materials such as carbide, ceramics, hardened steels, and similar substrates. It serves as a direct alternative to conventional superfinishing techniques. Typical install scenarios include surface grinders, belt grinders, and finishing machines used in tool shops, fabrication facilities, and precision machining environments. Coolant use during operation is recommended to extend belt life and maintain workpiece temperature.

Key Features

• Micron-graded diamond mineral for finer surface finishes on hardened materials
• Durable resin bond construction for extended service life
• Water-resistant X-weight cloth backing handles coolant-assisted operations
• Engineered for materials exceeding 62 Rockwell C hardness
• Alternative to conventional superfinishing belts and techniques
• Should be run with coolant to maintain performance and workpiece integrity

Compatibility

Designed as a replacement-style abrasive belt for belt grinders and surface finishing machines that accept an 18.93-inch by 2.5-inch belt. Verify machine belt size requirements before installation.

Installation Notes

Installation should be performed by a qualified machine operator or tool room technician familiar with abrasive belt equipment. Power down and de-energize the machine completely before changing belts. Confirm belt tracking and tension according to the machine manufacturer guidelines before running. Always operate with appropriate coolant flow as specified for diamond abrasive belts to prevent heat buildup and premature wear.
