Product Details
The 3M™ Cloth Belt 777F 4" x 60" 80 grit ceramic is designed to protect heat-sensitive alloys such as stainless steel, nickel alloys, and cobalt alloys by incorporating a grinding aid that reduces running temperatures, with abrasive bonded to the backing using resin for durability under high heat and pressure. This belt is recommended for applications involving stainless steel and exotic metal alloys including dimensioning parts, deburring, blending, and finishing castings and forgings. It features a proprietary 3M™ ceramic abrasive grain, a ceramic mineral engineered for enhanced toughness and hardness, blended with aluminum oxide to provide a harder, longer-lasting abrasive suitable for moderate to heavy stock removal. The ceramic/aluminum oxide blend offers superior cut-rate and durability compared to aluminum oxide abrasives, making it ideal for fast cutting and intense heat and stress conditions, suitable for moderate stock removal and surface preparation. The belts are available in various widths and lengths for sanding both wood and metal, compatible with most industrial belt sanders; wider belts for wide belt sanders used in dimensioning or finishing wood panels and smoothing metal sheets, medium widths for edge sanders to sand flat or narrow surfaces, and narrow belts for portable belt sanders to sand or blend wood pieces like cabinet doors. The 3M™ Cloth Belt 777F features a film splice for added strength in high-pressure grinding applications, with options such as an L-Flex splice available for increased flexibility, conformity, or a softer touch during finishing and blending. Warranty terms are included but not stated in this description.
