3M Cloth Belt 777F, 60 YF-weight, 3 in x 132 in, Film-lok, Single-flex, Case of 25

• 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

Trusted 3M Cloth Belt

The 3M Cloth Belt 777F is designed for reliable performance with a ceramic aluminum oxide grain blend. This blend cuts faster and lasts longer than traditional aluminum oxide, making it a smart choice for demanding tasks. The model 777F ensures consistent results across various applications.

Its single-flex design and Film-lok technology add strength and durability, especially under high pressure. These features make the belt suitable for tough grinding jobs while maintaining its integrity over time.

Precise Size And Format

This belt measures 3 inches by 132 inches, fitting a wide range of industrial belt sanders. The size supports both wood and metal sanding, allowing users to handle different projects with one belt type. The 60 YF-weight backing offers a sturdy base for effective abrasion.

Available as a case of 25 belts, this pack size is ideal for continuous use in busy workshops or production lines. Having multiple belts on hand reduces downtime and keeps operations running smoothly.

Durable Resin Bonding

The resin bond in the 3M Cloth Belt 777F resists heat deterioration, extending the belt’s life during intense grinding. This durability is crucial when working with heat-sensitive metals like stainless steel, where excessive heat can damage both the belt and the workpiece.

Because the bond maintains strength under pressure, the belt produces more parts per unit compared to traditional aluminum oxide belts. This efficiency means fewer belt changes and less interruption during work.

Heavyweight Backing Support

The heavyweight polyester backing supports high-pressure applications and can be used wet or dry. This flexibility allows the belt to adapt to different working conditions, enhancing its versatility across various materials and tasks.

Its robust backing also helps maintain belt shape and performance during demanding sanding or finishing jobs, ensuring consistent contact and better surface results.

Effective Stainless Steel Grinding

3M Cloth Belt 777F includes a grinding aid that reduces heat buildup when working on stainless steel and other exotic alloys. This feature helps prevent damage to heat-sensitive metals while improving grinding performance.

Recommended for deburring, blending, and finishing stainless steel, this belt excels in moderate stock removal and surface preparation. Its design supports precise metal finishing tasks with less wear and tear.
