3M 7010300303 Roloc Diamond Cloth Disc 674W 1.5 Inch

Product Description

The 3M 7010300303 Roloc Diamond Cloth Disc 674W is a quick-change abrasive disc engineered for grinding and polishing hard-to-grind materials. Diamond mineral is resin-bonded to a water-resistant cloth backing, giving the disc the strength to handle demanding surface work at speeds up to 30000 RPM. The backing supports both dry operation and use with liquid coolants, which helps extend abrasive life in high-heat applications. At 1.5 inches in diameter, the disc mounts via the Roloc attachment system for fast, tool-free disc changes. Typically installed and operated by machinists, toolroom technicians, or surface finishing specialists working with advanced materials.

This disc is suited for use on ceramics, carbide tooling, and hard-coated materials where conventional abrasives lose cutting efficiency quickly. The resin bond keeps diamond mineral firmly anchored during both dry and wet grinding cycles. The disc is well-matched to precision grinding tasks in toolrooms, maintenance shops, and manufacturing environments where consistent stock removal and finish quality on hard substrates are required.

Key Features

• Diamond mineral abrasive engineered for hard-to-grind materials including ceramics and carbides
• Resin bonding system supports both dry use and wet use with coolants
• Water-resistant cloth backing maintains integrity when coolants are applied
• Roloc quick-change attachment system enables fast disc swaps without tools
• Rated to 30000 RPM for compatibility with standard high-speed rotary tools

Compatibility

Designed for use with Roloc-compatible rotary tool holders and die grinders that accept 1.5 inch quick-change abrasive discs. Suitable for ceramics, carbide tooling, and hard-coated workpiece materials.

Installation Notes

Installation requires a Roloc-compatible mandrel or disc holder rated for the operating speed of this disc. Confirm the tool spindle speed does not exceed the 30000 RPM disc rating before use. When using coolants, ensure the tool and work area are set up to manage fluid safely. Inspect the disc for damage before each use and discard if the backing or bond shows signs of deterioration.
