3M 7000119212 Cubitron Ii 987C Fiber Disc 5 in 60 Grit

Product Description

The 3M 7000119212 is a Cubitron II 987C coated fiber disc engineered for medium to heavy-duty grinding, blending, and weld removal applications. It uses 3M Precision-Shaped Grain, a triangular ceramic abrasive that maintains sharp cutting points throughout the disc life, delivering a fast cut rate with reduced grinding pressure. The 5-inch diameter disc runs at up to 12000 RPM and carries a 60-grit designation, placing it in the aggressive stock-removal range. A stiff fiber backing paired with a strong resin bond gives the disc the rigidity needed for high-pressure operations. A built-in grinding aid reduces heat buildup at the workpiece surface, making it suitable for heat-sensitive alloys.

This disc is suited for metal fabrication shops, structural steel work, pipe welding operations, and robotic or pressure-assisted grinding lines. Typical applications include weld grinding, weld beveling, surface conditioning, and heavy burr removal on ferrous and select non-ferrous metals. The combination of high cut rate and extended disc life reduces changeout frequency, lowering downtime in high-volume production environments. Trade professionals in welding, pipefitting, and general metal fabrication will find this disc appropriate for angle grinder work where consistent cut performance across multiple parts per disc is required.

Key Features

• 3M Precision-Shaped Grain maintains sharp cutting points for fast material removal with reduced operator pressure
• Integrated grinding aid minimizes surface temperatures, protecting heat-sensitive alloys from discoloration and metallurgical damage
• Stiff fiber backing and strong resin bond resist tearing under high-pressure weld grinding and beveling conditions
• Extended disc life reduces changeout frequency, improving productivity in robotic and pressure-assisted applications
• 60-grit designation delivers aggressive stock removal suitable for heavy weld grinding and burr elimination

Compatibility

Designed for use on standard 5-inch angle grinders and disc grinders accepting Type 27 or flat fiber disc configurations; verify that the grinder RPM rating meets or exceeds 12000 RPM before use.

Installation Notes

Fiber discs of this type are installed and serviced by qualified metalworkers, welders, and grinding technicians. Before mounting, power down the grinder and confirm the backing pad and grinder spindle speed are rated at or above 12000 RPM. Inspect the disc for any damage, cuts, or delamination prior to each use and discard any damaged discs immediately. Always use the appropriate eye, face, and hand protection per applicable ANSI and OSHA grinding safety standards.
