  • 3Mô Ceramic Abrasive Grain offers excellent cut rate and life for better performance on aggressive applications
  • Layers of polyester cloth conform to contoured parts for consistent finishing
  • Heavyweight polyester backing provides added stiffness for tackling tough, high-pressure applications
  • Grinding aid helps reduce heat and grinding temperatures for long-term life and performance
  • Resin bonding resists deterioration from heat, extending the life of the abrasive
  • Closed coat provides greater grain density and a more consistent finish
  • Excellent for stainless steel

Featuring our high-performing ceramic grain resin-bonded to heavy-duty polyester backing, 3Mô Cloth Segment 777F delivers a high cut rate and efficient coverage to tackle aggressive applications on moderately contoured and shaped surfaces. It is ideal for sanding rough areas and grain setting on radiuses and contoured of metal parts.

Beat the Heat
Ideal for sanding the contours of heat-sensitive metals such as stainless steel tanks, 3Mô Cloth Segment 777F can be used in a wide variety of applications, including setting a linear finish, grinding, deburring, and blending,. Each layer of the segment contains highly efficient ceramic grain that is engineered to cut fast and handle heat and stress applications. We constructed this abrasive with a grinding aid that helps the abrasive stay cool during grinding, minimizing heat damage and improving overall performance.

Designed as a hardworking abrasive, 3Mô Cloth Segment 777F is manufactured with heat-resistant resin, a strong binding agent that adheres the abrasive to the backing and maintains the stability of the bond even in conditions under heat or pressure. This also allows for faster sanding and a higher cut rate. Closed coat construction features a dense spread of abrasive grains across the surface of the cloth. This design cuts fast and is ideal for grinding and setting a grain pattern with a consistent finish.

Fast-Cutting Ceramic Grain
3Mô Ceramic Abrasive Grain is chemically engineered with a unique "stay sharp" crystalline structure, which fractures frequently to continually create fresh-cutting edges for a super-fast cut, making it an excellent choice for high-volume industrial operations. For increased performance, 777F products feature aluminum oxide blended with 3M ceramic grain to produce a hard, long-lasting abrasive.

Unique Construction Follows Contours
3Mô Cloth Segment 777F is constructed of a number of layers of coated abrasive cloth. These layers are held together on one end by a sturdy plastic assembly or base that slides easily into the slots of a 3Mô RX Aluminum Hub or similar hub (not included). As the hub segments rotate over the substrate, the abrasive delivers a linear grain finish. Segments offer more conformability over a comparable belt, making them more suitable for a range of contours and shaped areas of a workpiece. Additionally, segments wear more slowly than belts due to the layered abrasive.

Cloth-backed abrasives are known for their durability and flexibility and are a good choice for stock removal and finishing across shaped pieces. 3M manufactures cloth segments of two types: slashed and unslashed. Slashed segments are cut into vertical strips that offer more conformability to inner contours. Unslashed segments are used when less conformability is required and a more aggressive cut is needed.

Ease of Use
The 3Mô RX Hub (sold separately) is an aluminum wheel with 20 evenly spaced tear-dropped shaped slots around the perimeter, into which the segments are inserted. These segments will also fit the keyhole shaped slots of hubs by other manufacturers. To hold the segments in place during operation, appropriately sized stamped metal flanges must be used on both sides of the hub.
