3M 7010328317 Flexible Diamond Qrs Cloth Disc 4 in

Product Description

The 3M 7010328317 is a flexible diamond QRS cloth disc engineered for grinding hard-to-work materials that conventional abrasives struggle to cut. Rated for a 4-inch diameter with a 1-inch arbor, this disc uses micron-graded diamond mineral secured by a metal bond for aggressive, consistent stock removal. The semi-flexible backing conforms to contours and edges, making it well-suited for finishing curved or irregular surfaces in stone, glass, ceramic, carbide, and composite materials. It mounts via a quick-release attachment system and is intended for use by fabricators, tool-and-die technicians, and composites finishers working with precision abrasive equipment.

This disc is designed for applications involving hard-to-grind materials such as stone, glass, ceramics, carbides, and composites in both production and job-shop environments. The open dot mineral pattern allows swarf and grinding debris to escape freely, reducing loading and extending usable disc life. It is appropriate for contour grinding, edge work, and surface finishing tasks where maintaining scratch consistency and cut rate across the full disc life is critical to part quality.

Key Features

• Micron-graded diamond mineral delivers aggressive cut and consistent scratch pattern on hard materials
• Open dot pattern allows swarf and debris to escape, reducing disc loading
• Metal bond anchors diamond securely for extended abrasive life
• Semi-flexible backing conforms to edges, contours, and curved surfaces
• Quick-release attachment system for fast disc changes

Compatibility

Designed as an OEM-style replacement or standard production disc for 4-inch random orbital and disc grinders equipped with a 1-inch arbor and compatible quick-release backing systems.

Installation Notes

Installation and disc changes should be performed by a qualified fabricator or abrasive equipment operator with the grinder fully powered down and unplugged. Verify the grinder spindle speed rating meets or exceeds the disc maximum operating speed before mounting. Inspect the backing pad and disc face for damage before each use. Follow applicable ANSI B7.1 safety standards for abrasive disc handling and operation.
