Product Details
The 3M™ Cloth Belt 777F measuring 3-1/2" x 15-1/2" with 80 grit ceramic abrasive is designed to protect against heat-sensitive alloys such as stainless steel, nickel alloys, and cobalt alloys. It features a grinding aid that reduces running temperatures, with abrasive bonded to the backing by resin to maintain durability under high heat and pressure. Recommended for use on stainless steel and exotic metal alloys, this belt is suitable for dimensioning parts, deburring, blending, and finishing castings and forgings. The proprietary 3M™ ceramic abrasive grain enhances toughness and hardness, while the blend of aluminum oxide with ceramic grain improves cut-rate and durability, making the belt ideal for moderate to heavy stock removal and surface preparation. These abrasive belts are available in various widths and lengths to fit most industrial belt sanders, with wider belts used for wide belt sanders on wood panels and metal sheets, medium widths for edge sanders on narrow surfaces, and narrow belts for portable sanders on smaller woodworking pieces. The 777F belt features a film splice for added strength in high-pressure grinding applications, offering a balance of toughness and durability for demanding tasks. The product complies with industry standards and includes warranty terms that cover manufacturing defects under typical use conditions.
