3M 7010325336 Diamond Cloth Abrasive Belt 25.21x3 Inch

Product Description

The 3M 7010325336 is a diamond cloth abrasive belt engineered for precision grinding and polishing of hard, difficult-to-finish materials including ceramics, carbide, and cast iron. The belt uses micron-graded diamond particles as the abrasive mineral, bonded to an x-weight waterproof cloth backing with a heat-resistant resin bond. The x-weight backing provides substantial tensile strength for extended-use applications under both dry and wet conditions. This belt is sized at 25.21 inches long by 3 inches wide and is sold as an individual unit. It is a tool-room and production-floor staple for machinists, toolmakers, and precision grinders working with hard substrates.

This belt is suited for bench-top and floor-standing belt grinding machines used in tool-and-die shops, carbide tooling operations, and precision fabrication environments. Its waterproof cloth backing allows use with liquid lubricants or coolants, making it compatible with wet-grinding setups commonly found in commercial and industrial machine shops. Applications include surface finishing, burr removal, and edge refinement on ceramics, sintered carbide, and gray or ductile cast iron components. It is not intended for soft metals or wood applications where diamond abrasives would be unnecessary.

Key Features

• Micron-graded diamond mineral delivers consistent, repeatable finishes on ceramics, carbide, and cast iron
• X-weight cloth backing resists tearing under sustained grinding pressure
• Heat-resistant resin bond minimizes thermal damage to the workpiece substrate
• Waterproof backing supports use with liquid lubricants and coolants in wet-grinding applications
• 25.21 inch by 3 inch format fits standard belt grinder configurations for that size range

Compatibility

Designed for use on belt grinding and polishing machines that accept a 25.21 inch by 3 inch abrasive belt. Suitable for operations involving ceramics, carbide, and cast iron workpieces.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with abrasive belt grinder equipment. Power down and lockout the machine before removing the worn belt and fitting the replacement. Verify belt tracking and tension per the grinder manufacturer's guidelines before resuming operation. Wear appropriate PPE including eye protection and gloves when handling and operating abrasive belts.
