Product Details
  • 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 high pressure and heat

3M™ Roloc™ Disc 777F features 3M-engineered high-performing ceramic abrasive grain blended with aluminum oxide for a combination of durability and cutting efficiency that increases productivity for both stock removal and finishing. The heavy, water-resistant polyester backing supports medium-pressure applications, a consistent cut-rate, and both wet and dry applications.

Use 3M™ Roloc™ Disc 777F in both wet and dry applications. Our 777F discs feature a blend of ceramic and aluminium oxide mineral that self-sharpens and offers improved durability and cut-rate over aluminium oxide alone. The heavy, water-resistant polyester backing is extremely durable – supporting medium pressure applications while allowing the disc to be run wet or dry. The Roloc attachment system enables quick and easy disc changes. A grinding aid reduces grinding temperatures, helping to protect heat sensitive alloys such as stainless steel nickel alloys and titanium. The abrasive is bonded to the backing with a heat resistant resin coating, staying robust even under pressure, heat or water.

Suggested Applications

  • Use in both wet and dry applications
