3M 7010362325 Cubitron Ii 987C Fiber Disc 4 in 80 Grit

Product Description

The 3M 7010362325 is a Cubitron II 987C coated fiber disc engineered for medium to heavy-duty grinding, weld grinding, and beveling applications. Built around 3M Precision-Shaped Grain technology, this disc maintains sharper cutting points longer than conventional abrasive minerals, delivering a higher cut rate with reduced grinding pressure. The 4-inch diameter disc runs at up to 15,000 RPM and is rated at 80 grit. A stiff fiber backing combined with a strong resin bond resists tearing under high-pressure use, while an integrated grinding aid helps manage heat buildup on heat-sensitive alloys. Licensed tradespeople and fabricators working in production environments will find meaningful cycle-time reductions compared to standard fiber discs.

This disc is suited for industrial and fabrication environments where consistent stock removal and disc longevity directly affect throughput. Typical applications include weld grinding, surface blending, and edge beveling on steel, stainless steel, and other ferrous and heat-sensitive alloys. The design is particularly well matched to robotic and pressure-assisted grinding setups, where reduced disc change frequency translates directly to less downtime. Manual angle grinder use on heavy fabrication work is equally supported.

Key Features

• 3M Precision-Shaped Grain holds super-sharp cutting points for fast stock removal at lower grinding pressure
• Higher cut rate and longer disc life compared to conventional fiber discs — fewer disc changes per job
• Stiff fiber backing and strong resin bond provide tear resistance in high-pressure weld grinding and beveling
• Integrated grinding aid reduces disc surface temperatures, protecting heat-sensitive alloys from discoloration or metallurgical damage
• Rated to 15,000 RPM for compatibility with standard right-angle and disc grinders
• Reduces changeout frequency and downtime in robotic and pressure-assisted grinding applications

Compatibility

Designed as an OEM-style replacement fiber disc for use on standard 4-inch right-angle grinders and disc grinders accepting Type 27 or compatible fiber disc configurations. No specific model compatibility data was provided in the product input.

Installation Notes

Installation and disc changes should be performed by qualified personnel following all applicable ANSI B11 and OSHA abrasive wheel safety standards. Always power down and disconnect or de-energize the grinder before mounting or removing the disc. Inspect the backing pad and disc for damage before each use, and confirm the grinder RPM rating meets or exceeds the disc maximum of 15,000 RPM. Never exceed the disc speed rating, and ensure the guard is properly in place before operation.
