3M 7010298825 Diamond Polishing Cloth Belt 25x3 in

Product Description

The 3M 7010298825 is a diamond polishing cloth belt designed for precision finishing of extremely hard materials. Sold under the 3M 652WY designation, this belt uses micron-graded diamond mineral bonded with a durable resin system to produce finer surface finishes than conventional abrasive belts. The X-weight cloth backing is water-resistant, giving the belt the rigidity and resilience needed for demanding grinding and superfinishing operations. It measures 25.21 inches in length and 3 inches in width. This belt is engineered specifically for materials rated harder than 62 on the Rockwell C scale, including carbide, ceramics, and hardened tool steels.

This belt is used in industrial and trade finishing applications where conventional abrasive media fails to achieve the required surface quality. It is well-suited for surface grinding, cylindrical finishing, and tool room work on hard substrates. The diamond mineral and resin bond combination supports consistent stock removal and finish quality across extended use cycles. Running this belt with coolant is required to maintain performance and prolong belt life. It is installed by machinists, tool grinders, and precision finishing technicians on belt grinding and finishing machines configured for the 25.21 by 3 inch belt size.

Key Features

• Micron-graded diamond mineral for finer, more consistent surface finishes
• Resin bond system provides long-lasting abrasive retention
• X-weight water-resistant cloth backing for rigidity and durability
• Engineered for materials harder than 62 Rockwell C, including carbide and hardened steels
• Requires coolant during operation to optimize performance and belt life
• Serves as a direct alternative to conventional superfinishing techniques

Compatibility

Designed for use on belt grinding and finishing machines that accept a 25.21-inch by 3-inch belt. Suitable for polishing and finishing operations on materials rated harder than 62 on the Rockwell C scale.

Installation Notes

Installation should be performed by a qualified machinist or finishing technician with the machine fully de-energized and locked out before belt replacement. Verify belt tracking and tension according to the machine manufacturer specifications before resuming operation. Coolant flow must be established prior to engaging the belt with the workpiece. Inspect the belt for tears or delamination before each use and do not operate a damaged belt.
