3M 7000045628 Roloc 777F Ceramic Disc 50 Grit 3 Inch

Product Description

The 3M 7000045628 is a Roloc 777F coated abrasive disc engineered for demanding stock removal and finishing applications. It combines 3M ceramic abrasive grain with aluminum oxide mineral on a heavy polyester backing rated for medium-pressure use in both wet and dry conditions. The ceramic-aluminum oxide blend self-sharpens during use, maintaining a consistent cut rate across the disc life. A grinding aid built into the formulation reduces heat buildup, making this disc well suited for heat-sensitive alloys including stainless steel, nickel alloys, and titanium. Licensed trades and fabrication professionals working on metal surfaces will find this disc a reliable production tool.

This disc is designed for use in metal fabrication, weld blending, surface prep, and finishing operations where consistent material removal is required. The 3-inch diameter and 50-grit rating position it for moderate to aggressive stock removal before transitioning to finer finishing steps. The water-resistant polyester backing holds up in coolant or water-assisted grinding processes, extending disc life in wet grinding applications common in aerospace, automotive, and general industrial metalworking environments.

Key Features

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

Compatibility

Designed for use with Roloc-compatible right-angle grinders and disc holders that accept 3-inch quick-change abrasive discs.

Installation Notes

Installation of this disc requires a Roloc-compatible disc pad or holder mounted on a right-angle grinder. Ensure the grinder is powered off and disconnected from any power source before attaching or removing the disc. Verify that the grinder RPM rating meets or exceeds the disc RPM rating before operation. Always wear appropriate PPE including eye protection and gloves when operating abrasive grinding equipment.
