Product Details
The 3M™ cloth belt 777F measures 1/2" x 18" and features a blend of 3M™ ceramic abrasive grain and aluminum oxide, designed for increased durability and cutting efficiency. It is suitable for moderate stock removal to finishing operations, supported by a heavyweight cloth backing that withstands high-pressure applications and performs well on heat-sensitive metals in both wet and dry conditions. The belt protects against heat-sensitive alloys such as stainless steel, nickel alloys, and cobalt alloys through a grinding aid that reduces running temperatures, with the abrasive bonded to the backing with resin to maintain durability under high heat and pressure. Recommended for use on stainless steel and exotic metal alloys, it is ideal for dimensioning parts, deburring, blending, and finishing castings and forgings. The proprietary 3M ceramic abrasive grain enhances toughness and hardness, and the aluminum oxide blend increases performance, making the belt harder and longer-lasting. Engineered for moderate to heavy stock removal, the ceramic/aluminum oxide abrasive blend cuts fast and handles intense heat and stress better than aluminum oxide abrasives. These belts come in various widths and lengths to fit most industrial belt sanders, with options suitable for wood and metal sanding, including wide belts for wide belt sanders to finish wood panels or metal sheets, medium-width belts for edge sanders on flat, narrow surfaces, and narrow belts for portable belt sanders used for sanding or blending wood pieces. The product carries a warranty as specified by 3M but warranty terms are not detailed here.
