Take advantage of increased durability and cutting efficiency with 3M™ Cloth Belt 777F. This belt features a blend of 3M™ Ceramic Abrasive Grain and aluminum oxide that outperforms aluminum oxide belts in stock removal and metal finishing applications. The heavyweight cloth backing supports high-pressure applications, performs well on heat-sensitive metals, and can be used dry or with lubricant.
- Ceramic aluminum oxide grain blend cuts faster and lasts longer than traditional aluminum oxide
- Produces more parts per belt than traditional aluminum oxide belts, requiring fewer belt changes
- Heavyweight polyester backing supports high-pressure applications and can be run wet or dry
- Contains a grinding aid to reduce heat and increase performance when grinding stainless steel
- Durable resin bond resists heat deterioration, which extends the life of the belt

What is the 3M™ Cloth Belt 777F used for?
The 3M™ Cloth Belt 777F is primarily used in metalworking applications for coarse sanding and grinding.
What does the "YF-weight" specification mean?
The "YF-weight" refers to the weight of the backing on which abrasive particles are bonded. In this case, it means a heavier cloth backing for increased durability and strength during use.
Can you explain what "Film-lok" means?
Sure, "Film-lok" refers to a type of attachment system where an adhesive-backed polyester film holds abrasive belts securely in place. This allows easy changes and helps prevent belt slippage during use.
3M™ Cloth Belt 777F is a high-performance abrasive belt that is perfect for grinding, deburring, blending, and finishing stainless steel, nickel alloys, and cobalt alloys. This belt contains a grinding aid that reduces running temperatures when used on heat-sensitive alloys. The abrasive grain is bonded to the backing with resin to maintain durability under high heat and pressure.Ceramic Abrasive Grain Boosts Performance
For increased performance, 777F products feature aluminum oxide blended with 3M ceramic abrasive grain for a harder, longer-lasting abrasive. The ceramic/aluminum oxide blend surpasses aluminum oxide abrasives in cut-rate and durability, making the Cloth Belt 777F an excellent choice for moderate stock removal and surface preparation.Sized to Suit Your Needs
These abrasive belts are available in various widths and lengths for sanding both wood and metal. 3M offers a broad selection of belts to fit most any industrial belt sander. Wider belts are used with wide belt sanders to dimension or finish wood panels, smooth rough-cut edges of metal sheets, or add a grain pattern to stainless steel sheets. Medium-width belts fit onto edge sanders for sanding flat, narrow surfaces such as panel edges; and narrow belts are used with portable belt sanders for sanding or blending wood pieces such as cabinet doors.Find Your Flex
Belts come with various flexibilities and splices that join the belt ends. 3M™ Cloth Belt 777F has a film splice for added strength when grinding in high pressure applications. When greater flexibility may be needed to increase conformity or for a softer touch for finishing and blending, an L-flex provides more flexibility than the standard flex, and a full flex belt is the most flexible.Applications
