Product Details
  • 3M™ ceramic aluminum oxide grain blend surpasses aluminum oxide abrasives in cut-rate
  • Durable ceramic/aluminum oxide blend extends belt life, producing more parts per belt and requiring fewer belt changes
  • Heavyweight polyester backing supports high-pressure, tough applications and can be run wet or dry
  • Contains a grinding aid to reduce heat and increase performance when used stainless steel and other exotic metals
  • Durable resin bond resists deterioration from heat, extending the life of the belt

3M™ Cloth Belt 777F features a blend of 3M™ Ceramic Abrasive Grain and aluminum oxide for increased durability and cutting efficiency and is suitable for moderate stock removal to finishing operations. The heavyweight cloth backing supports high-pressure applications, works well on heat-sensitive metals, and can be used in wet or dry applications.

3M™ Cloth Portable Belt 777F
Contains grinding aid which enhances performance on stainless steel and other exotic alloys
3M™ Cloth Belt 777F protects against heat sensitive alloys like stainless steel, nickel alloys and cobalt alloys with a grinding aid that reduces running temperatures, and the abrasive 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.

Our proprietary 3M™ Ceramic Abrasive Grain is a ceramic mineral designed to enhance toughness and hardness of the grain. For increased performance, 777F products feature aluminum oxide blended with 3M ceramic abrasive grain for a harder, longer-lasting abrasive. Perfect for moderate to heavy stock removal, ceramic abrasives are engineered to cut fast and handle intense heat and stress applications. 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.

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.

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 fullflex belt is the most flexible.
