3M 7100003179 Flexible Diamond Disc 1 Inch Roloca

Product Description

The 3M 7100003179 is a flexible diamond abrasive disc designed for flat, edge, contour grinding, and polishing on hard-to-grind materials including stone, glass, ceramic, metal, carbide, and composites. A metal-plated bond anchors micron-graded diamonds to a heavy-duty polyester backing, giving the disc both durability and the flexibility needed to conform to irregular surfaces. The Roloca quick-change attachment system allows twist-on and twist-off grade swaps without tools, reducing downtime during multi-step finishing work. At 1 inch in diameter, it is sized for precision work on small surfaces and tight geometries. Weighing 0.03 pounds, it adds no meaningful burden to handheld tool setups.

This disc is suited for trade and industrial applications where conventional abrasives load up or fail to cut efficiently on dense, non-ferrous, or brittle materials. Typical use cases include surface preparation, edge finishing, and polishing operations on stone fabrication, glass work, ceramic components, carbide tooling, and metal or composite parts. The open-dot abrasive pattern helps reduce loading, maintaining cutting efficiency across the disc life. It is appropriate for use by fabricators, tool and die professionals, and finish grinding technicians working with precision components.

Key Features

• Micron-graded diamonds in a metal-plated bond deliver aggressive, consistent cutting on hard materials
• Heavy-duty polyester backing conforms to flat surfaces, edges, and contoured profiles
• Open-dot abrasive pattern resists loading for sustained cutting performance
• Roloca twist-on and twist-off quick-change system simplifies grade changes and reduces downtime
• 1 inch diameter suits precision grinding and polishing on small or tight work areas

Compatibility

Designed for use with Roloca quick-change rotary tool systems that accept 1 inch twist-on abrasive discs. Suitable for grinding and polishing applications on stone, glass, ceramic, metal, carbide, and composite substrates.

Installation Notes

Installation and grade changes are performed by twisting the disc onto and off of a compatible Roloca mandrel without tools. Ensure the rotary tool is powered off and unplugged before attaching or removing the disc. Verify that the tool RPM rating is appropriate for the disc and the material being worked. Operators should follow applicable shop safety practices including eye and hand protection when grinding or polishing hard materials.
