3M 7000120367 Flexible Diamond Disc 1 Inch 30000 Rpm

Product Description

The 3M 7000120367 is a flexible diamond abrasive disc engineered for aggressive cutting and polishing on hard-to-grind materials including stone, glass, ceramic, metal, carbide, and composites. At 1 inch in diameter and rated to 30000 RPM, this disc uses a metal-plated bond to anchor micron-graded diamonds onto a heavy-duty polyester backing. The result is a disc capable of flat grinding, edge work, contour grinding, and polishing across a wide range of demanding substrates. It is part of the 3M Roloca system, which uses a quick-change twist-on and twist-off attachment mechanism designed to reduce downtime during grade changes on the shop floor or job site.

This disc is suited for professional trades and fabrication environments where precision material removal on hard or brittle substrates is required. Typical applications include toolroom work, stone and tile fabrication, glass polishing, ceramic component finishing, and carbide tool maintenance. The 1-inch format fits compact rotary tools and die grinders used in tight-access grinding situations. The open-dot abrasive pattern helps resist loading, keeping the cutting surface active longer between changes.

Key Features

• Micron-graded diamond abrasive bonded with metal-plated construction for consistent, aggressive cutting
• Heavy-duty polyester backing conforms to flat surfaces, edges, and contours
• Open-dot abrasive pattern resists loading on hard and brittle materials
• Roloca quick-change twist-on and twist-off system minimizes downtime during grade swaps
• Rated to 30000 RPM for use with high-speed rotary and die grinder tools
• 1 inch diameter suits compact tools and tight-access grinding applications

Compatibility

Designed for use with Roloca-compatible rotary tools and die grinders that accept 1-inch quick-change abrasive discs rated to 30000 RPM.

Installation Notes

Installation and disc changes should be performed with the tool powered off and disconnected from its power source. Verify that the tool spindle speed does not exceed the 30000 RPM rating marked on the disc before operation. Twist the disc onto the Roloca-compatible backer pad until it seats securely, and inspect the disc for damage before each use. Follow applicable workshop safety standards and always wear appropriate eye and hand protection when grinding or polishing hard materials.
