3M 7000045618 Roloc Disc 777F 1 Inch 36 Grit Ceramic

Product Description

The 3M 7000045618 is a Roloc-style coated abrasive disc in the 777F series, designed for stock removal and finishing on metal surfaces. At 1 inch in diameter with a 36-grit ceramic and aluminum oxide blend, the disc delivers aggressive cutting action that self-sharpens during use. A heavy polyester backing rated for medium-pressure applications keeps performance consistent through both wet and dry operation. Licensed HVAC, metal fabrication, and industrial trades rely on this disc when working with heat-sensitive alloys where controlled material removal is critical.

This disc is suited for grinding and blending on stainless steel, nickel alloys, and titanium, where heat buildup during abrasive work is a common concern. The built-in grinding aid reduces grinding temperatures, making it appropriate for alloys that are prone to surface discoloration or metallurgical damage from excess heat. The Roloc attachment system allows fast, tool-free disc changes on compatible right-angle grinders and die grinders in both production and field service settings.

Key Features

• Ceramic and aluminum oxide mineral blend self-sharpens for improved cut-rate and durability over standard aluminum oxide alone
• Grinding aid actively reduces heat buildup, protecting heat-sensitive alloys such as stainless steel, nickel alloys, and titanium
• Heavy polyester backing supports medium-pressure applications in wet or dry conditions
• Heat-resistant resin bond secures abrasive to backing under sustained pressure, heat, and moisture exposure
• Roloc attachment system allows fast, secure disc mounting and removal without additional hardware

Compatibility

Designed for use with Roloc-compatible right-angle grinders and die grinders that accept 1-inch quick-change abrasive discs.

Installation Notes

Installation and disc changes should be performed by trained grinding equipment operators following applicable ANSI B11 and OSHA 29 CFR 1910.215 safety standards. Power down and disconnect the grinder before mounting or removing the disc. Inspect the disc for damage before each use and confirm the tool RPM rating meets or exceeds the disc maximum speed rating. Eye protection, hearing protection, and appropriate gloves are required during grinding operations.
