3M 7000118300 Roloc 777F Disc 80 Grit 2 Inch

Product Description

The 3M 7000118300 is a Roloc 777F coated abrasive disc designed for stock removal and finishing on metal surfaces. It combines 3M-engineered ceramic abrasive grain with aluminum oxide to deliver a self-sharpening blend that outlasts standard aluminum oxide discs in cut rate and durability. The 2-inch diameter disc uses a heavy, water-resistant polyester backing rated for medium-pressure applications in both wet and dry conditions. A built-in grinding aid reduces heat buildup, making this disc suitable for heat-sensitive alloys. Licensed HVAC, metal fabrication, and industrial trades rely on this disc for consistent, controlled material removal.

This disc is used in metal fabrication, weld blending, deburring, and surface conditioning on stainless steel, nickel alloys, titanium, and other heat-sensitive metals. The 2-inch form factor fits standard Roloc-style quick-change angle grinder and die grinder attachments. It is well suited for tight spaces and detail work where a larger disc is impractical. At 80 grit, it handles aggressive stock removal while leaving a surface ready for finishing steps.

Key Features

• Ceramic and aluminum oxide blend self-sharpens for improved cut rate and durability over aluminum oxide alone
• Roloc quick-change attachment system allows fast, secure disc swaps without tools
• Heavy polyester backing supports medium-pressure applications in wet and dry conditions
• Grinding aid reduces heat at the workpiece, protecting heat-sensitive alloys such as stainless steel, nickel alloys, and titanium
• Heat-resistant resin bond holds abrasive firmly to backing under pressure, heat, and moisture

Compatibility

Designed for use with standard Roloc-style quick-change grinder and die grinder tool systems accepting 2-inch diameter discs.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and unplugged or the pneumatic air supply disconnected. Verify the tool arbor accepts the Roloc quick-change attachment before mounting. Wear appropriate eye and face protection per ANSI standards and inspect the disc for damage before each use. Do not exceed the maximum RPM rating of the disc or the tool.
