3M Cloth Belt 777F, 60 YF-weight, 1 in x 42 in, Film-lok, Single-flex, Case of 200

• 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

3M Cloth Belt 777F

The 3M Cloth Belt 777F is designed for high performance with a blend of ceramic aluminum oxide grain. This model offers faster cutting and longer life than traditional aluminum oxide belts. Its Film-lok technology ensures a strong splice for durability in tough grinding tasks.

Ideal for moderate stock removal and finishing, the 777F excels in deburring and blending stainless steel. The ceramic abrasive grain blend boosts cutting efficiency, making this belt a reliable choice for metalworking applications.

Heavyweight Backing Support

This belt features a heavyweight polyester backing that supports high-pressure applications. The backing is tough enough to be run wet or dry, providing versatility across different sanding environments.

The 1 inch by 42 inch size fits many industrial belt sanders, making it suitable for sanding wood and metal surfaces. Its durable backing helps maintain belt integrity during demanding jobs.

Flexible Film-lok Splice

The Film-lok splice on the 3M Cloth Belt 777F adds strength where the belt ends join. This single-flex design balances durability with enough flexibility for effective grinding performance.

Such a splice is especially useful in high-pressure applications, ensuring the belt holds up under stress. This feature complements the belt’s 60 YF-weight grade, optimized for tough sanding tasks.

Precise Size And Pack

Each belt measures 1 inch by 42 inches, a common size for edge and portable belt sanders. This dimension allows for detailed sanding and finishing on narrow or curved surfaces.

The belts come in a case of 200, providing a large supply for industrial or professional use. This pack size helps reduce downtime by minimizing belt changes during projects.

Grinding Aid For Stainless

The 3M Cloth Belt 777F includes a grinding aid that reduces heat buildup when working on stainless steel and other heat-sensitive alloys. This helps maintain performance and extends belt life.

It’s recommended for deburring, blending, and finishing stainless steel parts, making it a practical choice for metal fabrication and finishing shops. The belt’s durable resin bond also resists heat deterioration.
