  • Product Description
    • Ceramic aluminum oxide grain blend cuts faster and lasts longer than traditional aluminum oxide
    • 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
    • Heavyweight polyester backing supports high-pressure applications and can be run wet or dry
    • Produces more parts per belt than traditional aluminum oxide belts, requiring fewer belt changes
    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.

    Deburr, Blend and Finish Stainless Steel
    3M Cloth Belt 777F contains a grinding aid that reduces running temperatures when used on heat-sensitive alloys like stainless steel, nickel alloys and cobalt alloys. The abrasive grain is bonded to the backing with resin to maintain durability under high heat and pressure. This belt is recommended for use on stainless steel or other exotic metal alloys for dimensioning parts, deburring, blending, and finishing castings and forgings.

    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. Ceramic/aluminum oxide blend surpasses aluminum oxide abrasives in cut-rate and durability and makes 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. We offer 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. Our 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

    • Moderate stock removal
    • Deburring stainless steel
    • Finishing stainless steel
    • Surface preparation

    Brand And Model

    The 3M Cloth Belt 777F is a reliable abrasive belt designed for tough sanding tasks. This model combines 3M’s expertise with a ceramic aluminum oxide grain blend for faster cutting and longer life.

    Its unique formula outperforms traditional aluminum oxide belts, making it a solid choice for metal finishing and stock removal. The 777F model is built to handle demanding applications with consistent results.

    Grade And Weight Benefits

    This belt features an 80 YF-weight, which means it offers a durable heavyweight polyester backing. This backing supports high-pressure sanding and can be used wet or dry without losing strength.

    The heavyweight cloth backing also helps the belt resist heat deterioration, extending its lifespan during tough jobs. This makes the 80 YF-weight ideal for heavy-duty industrial use.

    Dimensions And Size

    The belt measures 3 inches by 132 inches, a size that fits many industrial belt sanders. This length and width combination is versatile for sanding wood panels, metal sheets, and other materials.

    Its size allows it to be used on wide belt sanders for panel dimensioning or on portable sanders for blending and finishing smaller pieces. The belt’s dimensions suit a variety of sanding needs.

    Format And Technology

    The 3M Cloth Belt 777F uses Film-lok technology with a single-flex design. This film splice adds strength and durability, especially in high-pressure grinding applications.

    The single-flex format balances flexibility and toughness, making it suitable for moderate stock removal and surface preparation. This technology helps the belt maintain performance over time.

    Pack Count And Usage

    This product comes as a case of 25 belts, providing a convenient supply for ongoing projects. Having multiple belts on hand reduces downtime caused by frequent belt changes.

    The case pack supports continuous work in industrial settings, especially when deburring, blending, or finishing stainless steel and other exotic alloys. It’s a practical choice for busy workshops.
