3M Cloth Belt 777F, 60 YF-weight, 1 in x 30 in, Fabri-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 Model

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 compared to traditional aluminum oxide belts. Its unique formulation makes it ideal for demanding metal finishing tasks.

Featuring the 777F grade, this belt is perfect for deburring, blending, and finishing stainless steel and other exotic alloys. The ceramic abrasive grain boosts cutting efficiency, making it a reliable choice for moderate stock removal.

Durable Weight And Backing

This belt uses a 60 YF-weight heavyweight polyester backing that supports high-pressure applications. The backing is tough enough to run wet or dry, providing versatility for different working conditions and materials.

The durable resin bond resists heat deterioration, extending the belt’s life even under intense grinding. This backing strength ensures consistent performance during heavy-duty sanding and finishing jobs.

Precise Size And Format

The belt measures 1 inch by 30 inches, fitting a variety of industrial belt sanders. Its size is suitable for detailed work on narrow surfaces or portable sanding tasks, offering flexibility across applications.

Available as a case of 200, this pack count supports large-scale projects and frequent belt changes. The Fabri-lok format and single-flex design provide added strength and reliability during use.

Grinding Aid For Stainless

3M Cloth Belt 777F contains a grinding aid that reduces heat buildup when working on stainless steel. This feature helps maintain performance and prevents damage to heat-sensitive metals during grinding.

It’s especially effective for deburring and finishing stainless steel, nickel, and cobalt alloys. The grinding aid improves belt life and surface quality, making it a smart choice for precision metalwork.

Flexible Splice Options

The belt includes a film splice for added strength in high-pressure grinding applications. This splice type ensures durability and reduces the chance of belt failure during tough sanding tasks.

For applications needing more flexibility, options like L-flex and full flex belts are available. These provide softer touch and better conformity for blending and finishing, adapting to various project needs.
