3M 7010328306 Flexible Diamond Disc 1.5 Inch Roloca

Product Description

The 3M 7010328306 is a flexible diamond abrasive disc engineered for aggressive cutting and finishing on hard-to-grind materials including stone, glass, ceramic, metal, carbide, and composites. At 1.5 inches in diameter, this disc features a metal-plated bond that anchors micron-graded diamonds to a heavy-duty polyester backing. The construction supports flat grinding, edge work, contour grinding, and polishing passes. It is installed using the Roloca quick-change twist-on and off system, which allows fast grade swaps with minimal downtime. Fabricators, toolmakers, and finishing technicians working with precision or hard-substrate materials are the primary users of this disc.

This disc is suited for bench-top, handheld rotary, and contour-finishing applications where conventional abrasives load up or wear prematurely. The open-dot abrasive pattern helps prevent loading when working across dense or non-porous materials. Typical use cases include precision grinding of ceramic components, glass edge finishing, carbide tool touch-up, and composite surface preparation in shop or field environments. Its flexible polyester backing allows the abrasive surface to conform to curved or irregular contours without losing cutting effectiveness.

Key Features

• Micron-graded diamonds in a metal-plated bond for consistent, aggressive cutting action
• Open-dot abrasive pattern resists loading on dense, non-porous surfaces
• Heavy-duty flexible polyester backing conforms to flat, edge, and contoured workpiece geometry
• Roloca quick-change twist-on and off attachment system for fast grade changes and reduced downtime
• Compatible with hard-to-grind substrates: stone, glass, ceramic, metal, carbide, and composites

Compatibility

Designed for use with Roloca quick-change rotary tool systems that accept 1.5-inch diameter twist-on abrasive discs.

Installation Notes

This disc is installed and removed by hand using the Roloca twist-on and off interface — no tools are required for disc changes. Ensure the host tool is powered off and unplugged before mounting or removing any abrasive disc. Verify that the tool spindle speed rating meets or exceeds the maximum rated speed of the disc before operation. Always wear appropriate eye and hand protection when operating rotary abrasive tools.
