Product Details
The 3M™ Cloth Belt 777F measures 37 inches by 60 inches and features a ceramic 50 grit abrasive. It combines 3M™ ceramic abrasive grain with aluminum oxide for enhanced durability and cutting efficiency, suitable for moderate stock removal to finishing operations. The belt uses a heavyweight cloth backing that supports high-pressure applications, works well on heat-sensitive metals, and is effective in both wet and dry conditions. It 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. The abrasive is resin-bonded to the backing, maintaining durability under high heat and pressure. Recommended for stainless steel and exotic metal alloys, this belt is ideal for dimensioning parts, deburring, blending, and finishing castings and forgings. The proprietary 3M™ ceramic abrasive grain enhances toughness and hardness, while the aluminum oxide blend improves cut rate and durability compared to standard aluminum oxide abrasives. Ceramic abrasives are engineered for fast cutting and resistance to intense heat and stress, making this belt an excellent choice for moderate to heavy stock removal and surface preparation. Available in multiple widths and lengths, these belts accommodate various industrial belt sanders, with wider belts used for dimensioning and finishing wood panels or smoothing metal sheets, medium-width belts for edge sanding flat or narrow surfaces, and narrow belts for portable belt sanders. The product includes warranty terms that ensure reliability and performance under specified conditions.
