3M™ Roloc™ 777F Aluminum Oxide/Ceramic Disc

• A blend of ceramic and aluminum oxide mineral self-sharpens and offers improved durability and cut-rate over aluminum oxide
• 3M™ Roloc™ attachment system enables efficient and secure attachment and removal of the disc
• Polyester backing is extremely tough to support medium-pressure applications while maintaining consistent performance in both wet and dry applications
• Grinding aid reduces grinding temperatures for processes involving heat-sensitive alloys such as stainless steel, nickel alloys, and titanium
• Heat-resistant resin coating bonds abrasive to backing for durability under pressure, heat, and water
