3M 7100029971 Flexible Diamond Disc 1 Inch Roloca 6234J

Product Description

The 3M 7100029971 is a flexible diamond abrasive disc in the Roloca 6234J series, designed for precision grinding and polishing of hard-to-grind materials. A metal-plated bond anchors micron-graded diamonds to a heavy-duty polyester backing, delivering consistent cutting performance across flat surfaces, edges, and contours. The disc measures 1 inch in diameter and is sold individually. It suits applications where conventional abrasives struggle, including work on stone, glass, ceramic, metal, carbide, and composite materials. Licensed trades and skilled fabricators rely on this disc for controlled stock removal and surface finishing in tight or contoured areas.

This disc is used in hand-tool and bench grinding applications where conformance to irregular or contoured workpiece geometry is required. The Roloca quick-change twist-on and twist-off mounting system allows fast grade changes without tools, reducing downtime during multi-step grinding and polishing sequences. Typical users include glaziers, stone fabricators, tool-and-die machinists, carbide toolmakers, and composite technicians working in both shop and field environments.
