3M 7100177937 Diamond Cloth Disc 674W 2 Inch 25000 Rpm

Product Description

The 3M 7100177937 is a 2-inch diamond cloth abrasive disc designed for grinding and polishing hard-to-grind materials in demanding fabrication and finishing applications. Diamond mineral is resin-bonded to a durable, water-resistant cloth backing, allowing use either dry or with liquid coolants. The disc is rated to 25000 RPM and is sold individually. It is suited for use by machinists, toolroom technicians, and skilled tradespeople who work with extremely hard substrates where conventional abrasives fall short.

This diamond cloth disc is intended for use on ceramics, carbides, and hard-coated materials. The cloth backing withstands coolant exposure, which typically extends abrasive service life during wet grinding operations. Its resin bond maintains consistent mineral exposure throughout the disc life, delivering repeatable surface finishes across production runs or precision repair work. It is compatible with a variety of attachment systems, making it adaptable to standard rotary grinders and polishing tools used in shop environments.
