3M 7100003670 Roloc Flexible Diamond Disc 2 in M20

Product Description

The 3M 7100003670 is a Roloc flexible diamond disc designed for grinding and polishing hard-to-process materials including stone, glass, ceramic, metal, carbide, and composites. The disc uses a metal-plated bond that securely anchors micron-graded diamonds to a heavy-duty, water-resistant polyester backing. Rated at M20 micron diamond grain, this disc is suited for flat, edge, and contour grinding applications where conventional abrasives struggle. At 2 inches in diameter with a Roloc quick-change mount, it threads on and off standard Roloc-compatible tools without additional hardware. Each disc weighs approximately 0.04 pounds.

This disc is intended for professional use in fabrication, toolroom, and surface preparation settings. It is well suited for technicians working with carbide tooling, glass components, ceramics, and composite materials that require precise material removal and surface finishing. The flexible polyester backing allows the disc to conform to contoured and edge profiles, making it useful in both flat-stock and shaped-workpiece applications where rigid abrasives would leave uneven results.

Key Features

• Metal-plated bond anchors micron-graded diamonds securely to the backing
• M20 micron diamond grade for controlled material removal and fine finishing
• Heavy-duty, water-resistant polyester backing supports wet or dry use
• Flexible construction conforms to flat, edge, and contour surfaces
• Roloc quick-change attachment for fast disc swaps on compatible tools
• Compatible with hard-to-grind materials: stone, glass, ceramic, metal, carbide, and composites

Compatibility

Designed for use with standard Roloc quick-change tool systems. Suitable for grinding and polishing applications on stone, glass, ceramic, metal, carbide, and composite materials.

Installation Notes

This disc is installed and removed by hand using the Roloc twist-lock mechanism — no wrenches required. Ensure the tool spindle is fully stopped and power is disconnected before changing discs. Follow the tool manufacturer's maximum RPM rating and do not exceed the disc's rated speed. Eye protection and appropriate PPE should be worn during all grinding and polishing operations.
