3M 7000118301 Abrasive Disc 777F P100 2 Inch Ceramic

Product Description

The 3M 7000118301 is a 2-inch coated abrasive disc in the 777F series, designed for both stock removal and finishing in metal fabrication and surface preparation applications. It combines 3M-engineered ceramic abrasive grain with aluminum oxide for a self-sharpening blend that delivers improved cut-rate and durability compared to aluminum oxide alone. The disc features a heavy, water-resistant polyester backing rated for medium-pressure applications in both wet and dry environments. A grinding aid built into the formulation reduces heat buildup, making this disc appropriate for work on heat-sensitive alloys. It is installed via the Roloc attachment system for fast, secure disc changes.

This disc is suited for metal grinding, blending, and finishing tasks on materials including stainless steel, nickel alloys, and titanium where heat control is critical. The 2-inch diameter fits compact angle grinders, die grinders, and right-angle tools equipped with a Roloc-compatible mandrel. It is commonly used in fabrication shops, aerospace maintenance, and field service environments where consistent cut performance and quick disc swaps are required. Both wet and dry grinding setups are supported by the polyester backing construction.

Key Features

• Ceramic and aluminum oxide blend self-sharpens for improved durability and sustained cut-rate over straight aluminum oxide
• Roloc attachment system provides fast, secure disc mounting and removal without tools
• Heavy polyester backing withstands medium-pressure applications in wet and dry conditions
• Grinding aid reduces heat generation, suitable for heat-sensitive alloys such as stainless steel, nickel alloys, and titanium
• Heat-resistant resin bond holds abrasive to backing under pressure, heat, and water exposure
• P100 grit designation balances stock removal speed with surface finish quality

Compatibility

Designed for use with Roloc-compatible mandrels on die grinders, angle grinders, and right-angle tools accepting 2-inch coated abrasive discs.

Installation Notes

Installation is performed by aligning the disc hub with a Roloc-compatible mandrel and pressing firmly while rotating to lock. Confirm the mandrel is rated for the tool RPM before use. Power down and disconnect the tool from its power source before mounting or removing the disc. Follow applicable shop safety protocols and wear appropriate eye and face protection during grinding operations.
