Product Details
The 3M™ Cloth Belt 577F 1/2" x 12" features alumina zirconia abrasive grain, which provides increased cutting efficiency compared to aluminum oxide belts. It is backed with a heavy, water-resistant polyester backing designed to withstand high-pressure applications and edge work, supporting both wet and dry operations. This belt is recommended for use on aluminum, mild steel, stainless steel, and 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, the belt includes a grinding aid that reduces running temperatures. The abrasive is firmly bonded to the backing with resin to ensure durability under high heat and pressure. Alumina zirconia's frequent fracturing produces sharp points for a faster cut rate, making it suitable for heavy stock removal and high-pressure grinding. The cloth belt is available in various widths and lengths to fit different belt sanding tools and applications, with wider belts used on wide belt sanders for flat finishing, medium-width belts on backstands or feed-thru style finishers, and narrow belts on backstands or file tools for accessing right-angle corners. Typical applications include blending, coating removal, deburring, and high-pressure grinding, serving industries such as builders hardware, medical instruments, metal fabrication, metal implants, plating and polishing, plumbing fixtures, and turbine engines. Warranty information is subject to 3M terms.
