3M 7100022116 Diamond Cloth Disc 674W 2 Inch 25000 Rpm

Product Description

The 3M 7100022116 is a 2-inch diameter diamond cloth disc in the 674W series, engineered for grinding and polishing hard-to-grind materials. The diamond abrasive mineral is resin-bonded to a water-resistant cloth backing, allowing the disc to run dry or with liquid coolants. Rated at 25000 RPM, it delivers consistent, long-lasting cut performance on demanding surfaces. The Roloca attachment system is integrated into the disc design for fast, tool-free disc changes during production runs. This disc is suited for precision grinding applications where standard aluminum oxide or silicon carbide abrasives lose cutting efficiency quickly.

The 674W disc is intended for use on ceramics, carbides, and hard-coated materials where close-tolerance stock removal or surface finishing is required. It is commonly used in tool and die shops, machine shops, and manufacturing environments. The water-resistant backing makes it practical for wet grinding setups where coolant is used to manage heat and extend abrasive service life. Each disc is sold individually with a minimum order quantity of 10 units.

Key Features

• Diamond mineral abrasive rated for hard-to-grind materials including ceramics and carbides
• Resin-bonded construction supports both dry use and coolant-assisted wet grinding
• Water-resistant cloth backing extends abrasive life when used with coolant
• Roloca attachment system enables faster disc changes without additional tooling
• 2-inch diameter at 25000 RPM maximum operating speed

Compatibility

Designed for use with Roloca-compatible grinding tools and backup pads that accept 2-inch coated abrasive discs. Suitable for grinding and finishing ceramics, carbides, and hard-coated materials.

Installation Notes

Installation and disc changes should be performed by qualified personnel with the tool fully powered down and isolated from its power source. Verify the tool spindle speed does not exceed the 25000 RPM maximum rating before mounting. Inspect the disc for damage before each use and never use a damaged or deformed disc. When using coolant, confirm the coolant is compatible with resin-bonded abrasives and follow applicable shop safety protocols.
