3M Cloth Belt 777F, 36 YF-weight, 6 in x 48 in, Film-lok, L-flex, 10/Carton, Case of 20

• 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 offers reliable performance with its 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 is designed to handle tough jobs efficiently.

Ideal for metal finishing and stock removal, this belt supports high-pressure applications thanks to its heavyweight polyester backing. The 6 in x 48 in size fits many industrial belt sanders, providing versatility across projects.

Efficient Grinding Aid

Containing a grinding aid, the 3M Cloth Belt 777F reduces heat buildup during use. This feature is especially useful when working with stainless steel, helping to maintain performance and protect heat-sensitive metals.

With a Film-lok splice, the belt gains added strength for high-pressure grinding. This technology ensures durability and consistent results, even under demanding conditions.

Durable Resin Bonding

The belt’s durable resin bond resists heat deterioration, extending its lifespan. This means fewer belt changes and more productivity on the job. The resin bond keeps the abrasive grain firmly attached during tough grinding tasks.

Thanks to this durability, the 777F belt produces more parts per belt than traditional aluminum oxide belts. This efficiency reduces downtime and overall costs in industrial settings.

Versatile Size Options

Measuring 6 in x 48 in, this belt size suits a variety of sanding needs. It’s available in packs of 10 per carton and cases of 20, making it easy to stock up for ongoing projects.

The size fits wide belt sanders for wood panel finishing and metal sheet smoothing. Medium and narrow widths are also offered for edge sanding and portable belt sanders, covering many applications.

Flexible L-Flex Design

The L-flex backing provides more flexibility than standard belts, allowing better conformity to surfaces. This flexibility is great for finishing and blending tasks where a softer touch is needed.

Combined with the Film-lok splice, the 3M Cloth Belt 777F balances strength and flexibility. This makes it suitable for moderate stock removal, deburring, and surface preparation on stainless steel and exotic alloys.
