3M 7010309472 Flexible Diamond Abrasive Disc 1 in

Product Description

The 3M 7010309472 is a Roloca flexible diamond abrasive disc designed for aggressive cutting 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 the rigidity needed for flat and edge work and the flexibility required for contour grinding and polishing. The quick-change Roloca twist-on and twist-off attachment system allows rapid grade changes without tools, reducing downtime during production or service work. Each disc weighs 0.06 pounds and measures 1 inch in diameter.

This disc is suited for trade and industrial applications where conventional abrasives load up or wear prematurely on dense or brittle substrates. Typical use cases include grinding and finishing operations on stone countertops, glass edges, ceramic tile, hardened metal components, carbide tooling, and fiber-reinforced composites. The open-dot abrasive pattern helps prevent swarf buildup, extending usable disc life across extended work sessions. It is sold individually and is compatible with Roloca-style quick-change backing systems.

Key Features

• Micron-graded diamonds anchored with metal-plated bond for consistent, aggressive material removal
• Heavy-duty polyester backing supports flat grinding, edge work, and contour polishing
• Open-dot abrasive pattern resists loading on hard and dense materials
• Roloca twist-on and twist-off design enables fast grade changes with minimal downtime
• Rated for stone, glass, ceramic, metal, carbide, and composite substrates

Compatibility

Designed for use with Roloca-style quick-change backing pads and systems. Suitable for grinding and polishing applications on hard-to-grind materials where a flexible diamond abrasive disc is specified.

Installation Notes

Installation and disc changes should be performed by qualified personnel following all applicable tool manufacturer guidelines and shop safety protocols. Ensure the grinder or polisher is fully powered down and unplugged before mounting or removing the disc. Confirm the backing pad is rated for the intended RPM before operation. Eye and face protection, along with appropriate respiratory protection, should be worn when grinding stone, glass, ceramic, or composite materials.
