The 3M™ Cloth Belt 577F features alumina zirconia abrasive grain for increased cutting efficiency, and is backed with a heavy, water-resistant polyester backing that stands up to high-pressure applications and edge work. The durable backing ensures long life and supports both wet and dry operations.The 3M Cloth Belt 577F can be used on aluminum, mild steel, and stainless steel or other exotic metal alloys for dimensioning parts, deburring, blending, and finishing castings and forgings. To protect heat-sensitive alloys such as stainless steel, nickel alloys, and cobalt alloys, a grinding aid on the belt reduces running temperatures. Additionally, the abrasive is firmly bonded to the backing with resin to maintain durability under high heat and pressure. Abrasive belts come in many different widths and lengths and are used on a variety of different belt sanding tools for many different metalworking applications. Wider belts are used with wide belt sanders for flat finishingto smooth rough cut edges of metal sheets, or add a grain pattern to stainless steel sheets. Medium-width belts are generally used on a backstand for weld removal or on a feed-thru style flat finisher for imparting a finish on sheets or coils. Narrow belts can be used on backstands for grinding and finishing, or on file tools to access right angle corners for finishing.
