The 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.The 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. 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. For increased performance, this product features 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 3M 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. 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.
