3M 7100100999 Roloca 782C Fiber Disc 80 Grit 2 Inch

Product Description

The 3M 7100100999 is a 2-inch coated fiber disc in the Roloca 782C series, engineered for ultra-rapid material removal on carbon steel. It features 3M Precision Shaped Grain, an advanced abrasive geometry that delivers higher cut rates and longer disc life compared to conventional fiber discs. The disc runs at a maximum speed of 12,000 RPM and is built on a stiff fiber backing with a strong resin bond for tear resistance under load. It is designed for use by fabricators, welders, and metalworkers performing aggressive stock removal and surface refinement tasks.

This disc is suited for heavy-duty metalworking applications in fabrication shops, manufacturing facilities, and field welding environments. Primary use cases include weld removal, weld blending, beveling, edge chamfering, and finish refinement on carbon steel workpieces. The Roloca attachment system locks the disc securely to a compatible Roloca backing pad without tools, making disc changes fast and straightforward during production use.

Key Features

• 3M Precision Shaped Grain delivers higher cut rates and more parts per disc than conventional abrasives
• Rated to 12,000 RPM for compatibility with standard angle grinders
• Stiff fiber backing and strong resin bond resist tearing under heavy grinding loads
• Roloca attachment system secures disc without tools for fast changeovers
• Long-lasting abrasive mineral reduces disc consumption and cost per part
• Effective for weld removal, beveling, edge chamfering, and surface blending on carbon steel

Compatibility

Designed for use with Roloca-compatible backing pads. The Roloca attachment system is required for proper disc mounting and secure operation.

Installation Notes

Installation and disc changes are performed by the operator without tools using the Roloca locking attachment. Always verify the grinder RPM rating meets or exceeds the disc maximum of 12,000 RPM before mounting. Inspect the disc for damage before each use and never use a cracked or delaminated disc. Follow applicable ANSI B7.1 safety standards for abrasive wheel use, including use of appropriate guarding and personal protective equipment.
