3M 7010308146 Cubitron Ii 982C Fibre Disc 5 in 80 Grit

Product Description

The 3M 7010308146 is the Cubitron II 982C coated fibre disc, engineered for heavy-duty grinding on carbon steel and similar ferrous metals. It uses 3M Precision-Shaped Grain, a triangular ceramic abrasive that maintains sharp cutting points throughout the disc life, delivering cut rates up to twice those of conventional fibre discs. At 5 inches in diameter and 80 grit, this disc is built for medium to high-pressure weld grinding, beveling, and stock removal. A stiff fibre backing combined with a strong resin bond resists tearing under aggressive load. Rated to 12000 RPM. Fabricators, welders, and metal finishing technicians are the primary users of this disc.

This disc is suited for manual angle grinder use, robotic grinding cells, and pressure-assisted grinding systems. Its lower required grinding pressure reduces operator fatigue during repetitive or extended grinding operations, making it a practical choice for production environments where throughput and parts-per-disc metrics matter. Common applications include weld seam removal, edge beveling, and surface conditioning on carbon steel workpieces in fabrication shops and industrial maintenance settings.

Key Features

• 3M Precision-Shaped Grain maintains sharp triangular points for fast cutting with reduced operator pressure
• Ceramic grain construction lasts up to twice as long as standard ceramic abrasives and wears evenly to run cool
• Stiff fibre backing and strong resin bond provide tear resistance under high-pressure grinding loads
• Compatible with manual, robotic, and pressure-assisted grinding applications
• Reduces disc changeouts and downtime in production grinding environments
• Rated at 12000 RPM for use with standard angle grinders

Compatibility

Designed for use on carbon steel in medium to high-pressure grinding applications including weld grinding and beveling. Fits standard 5-inch angle grinders and pressure-assisted grinding equipment.

Installation Notes

This disc is installed and replaced by fabricators, welders, or trained grinding equipment operators. Verify the grinder RPM rating meets or exceeds the disc maximum of 12000 RPM before mounting. Inspect the disc for damage before each use and never use a cracked or deformed disc. Follow ANSI B7.1 safety standards for abrasive wheel mounting and operation, including the use of appropriate guards and personal protective equipment.
