3M 7000000550 Roloc Disc 60 Grit Ceramic 2 Inch

Product Description

The 3M 7000000550 is a 2-inch Roloc quick-change abrasive disc designed for both stock removal and finishing operations in metalworking applications. It uses a blend of ceramic and aluminum oxide abrasive grain engineered to self-sharpen during use, maintaining a consistent cut rate over the disc's service life. A heavy polyester backing supports medium-pressure grinding in wet or dry conditions, while a heat-resistant resin bond keeps the abrasive firmly attached under pressure and elevated temperatures. Licensed HVAC, fabrication, and general metalworking technicians typically use this disc for work on heat-sensitive alloys including stainless steel, nickel alloys, and titanium.

This disc is suited for surface preparation, weld blending, and general grinding on ferrous and non-ferrous metals in both shop and field settings. The 60-grit ceramic formulation is appropriate for medium-aggression material removal where a refined surface finish is required after stock removal. The water-resistant polyester backing makes it usable in wet grinding applications where coolant or water is applied to control heat. Professionals performing fabrication, repair, or surface conditioning on heat-sensitive alloys will find the grinding aid particularly useful for controlling workpiece temperature.

Key Features

• Ceramic and aluminum oxide blend self-sharpens during use for improved cut rate and durability over aluminum oxide alone
• Roloc attachment system allows fast, secure disc changes without tools
• Heavy polyester backing handles medium-pressure applications in both wet and dry environments
• Grinding aid reduces heat buildup, making it suitable for stainless steel, nickel alloys, and titanium
• Heat-resistant resin bond maintains abrasive adhesion under pressure, heat, and water exposure
• 2-inch diameter fits standard Roloc-compatible backup pads and right-angle grinders

Compatibility

Designed for use with standard Roloc-compatible backup pads and right-angle grinders or die grinders accepting 2-inch quick-change abrasive discs.

Installation Notes

Mounting and removal require a Roloc-compatible backup pad — press and twist to seat, reverse to release. Verify the backup pad and grinder RPM rating meet or exceed the disc speed rating before use. Wear appropriate PPE including eye protection and gloves during disc changes and grinding operations. Inspect the disc for damage before each use and discard any disc showing tears, delamination, or unusual wear patterns.
