3M 051144-76634 Roloc Discs 777F, Ceramic/Regular Alumina Mix, 3 In Dia., 80 Grit

The 3m Roloc Disc 777F is a high-performance abrasive disc designed for heavy-duty metalworking applications where efficient material removal is critical. It features a blend of ceramic and aluminum oxide minerals that aggressively cut through tough materials, solving the problem of slow grinding and short abrasive lifespan in industrial environments.

• The ceramic and aluminum oxide mineral blend provides superior durability and an improved cut-rate compared to standard aluminum oxide discs, maximizing efficiency.
• The integrated 3m Roloc attachment system ensures quick and secure disc changes, minimizing downtime and increasing productivity on the jobsite.
• A grinding aid is incorporated to reduce heat build-up when working with heat-sensitive metals like stainless steel, nickel alloys, and titanium, which helps maintain the alloy’s integrity.

This disc is best suited for professionals in metal fabrication, maintenance, repair, and overhaul (MRO) operations who require reliable, aggressive abrasion for tasks such as deburring, surface preparation, and heavy grinding.

• Diameter: 3 in
• Grit: 80
• Abrasive Material: Ceramic Aluminum Oxide
• Attachment System: Roloc (TSM, TR, or TS depending on specific part number)
