3M Cloth Belt 777F, P120 YF-weight, 37 in x 75 in, Film-lok, Single-flex,Case of 5

• 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 its P120 YF-weight grade. This belt blends ceramic aluminum oxide grain for faster cutting and longer life compared to traditional aluminum oxide belts. It’s a solid choice when you need consistent results on metal and wood surfaces.

Ideal for demanding tasks, the 777F model supports high-pressure applications thanks to its heavyweight polyester backing. This backing also allows the belt to be used wet or dry, making it versatile for various grinding and finishing jobs.

Precise Size And Format

Measuring 37 inches by 75 inches, this belt fits a wide range of industrial belt sanders. The size is perfect for both wood and metal sanding, providing ample coverage for panel edges or larger surfaces. Its format includes Film-lok technology for added strength.

Sold as a case of 5, these belts offer convenience and value for continuous work without frequent reordering. The Film-lok splice ensures durability under high pressure, reducing downtime during heavy use.

Enhanced Cutting Efficiency

The ceramic aluminum oxide grain blend in the 777F belt cuts faster and lasts longer than traditional aluminum oxide. This means you get more parts per belt, reducing the need for frequent belt changes and improving overall productivity.

Additionally, the durable resin bond resists heat deterioration, extending the belt’s life even under tough grinding conditions. This combination makes the belt a cost-effective solution for moderate stock removal and surface preparation.

Specialized Stainless Steel Use

This belt contains a grinding aid that reduces heat buildup when working with stainless steel and other heat-sensitive alloys. This feature helps maintain material integrity and improves finish quality during deburring and blending tasks.

Recommended for stainless steel, nickel, and cobalt alloys, the 777F belt excels in dimensioning parts and finishing castings or forgings. Its ability to run wet or dry adds flexibility for various metalworking applications.

Flexible Backing Options

The heavyweight polyester backing supports high-pressure use while offering different flexibilities. The 777F belt’s Film-lok splice provides strength, but other flex options like L-flex or full flex are available for softer touch and better conformity.

This range of flexibilities allows you to choose the right belt for your specific finishing or blending needs. Whether you need a stiff belt for aggressive grinding or a flexible one for delicate surfaces, there’s a suitable option.
