Product Details
The 3M™ cloth belt 577F measures 1/2" x 18" and features alumina zirconia abrasive grain, which provides increased cutting efficiency compared to aluminum oxide belts. It has a heavy, water-resistant polyester backing designed to withstand high-pressure applications and edge work, ensuring durability for both wet and dry operations. This belt is recommended for use on aluminum, mild steel, stainless steel, and other exotic metal alloys for tasks such as dimensioning parts, deburring, blending, and finishing castings and forgings. A grinding aid on the belt helps reduce running temperatures to protect heat-sensitive alloys including stainless steel, nickel alloys, and cobalt alloys. The abrasive is resin-bonded to the backing to maintain durability under high heat and pressure. Alumina zirconia continuously fractures to produce sharp points for faster cutting rates, making it suitable for heavy stock removal and high-pressure grinding. The belts come in various widths and lengths to fit different industrial belt sanding tools, with wider belts used for wide belt sanders for flat finishing and grain patterning, medium-width belts for weld removal or finish on sheets or coils, and narrow belts for grinding and finishing in tight corners or on file tools. Typical applications include blending, coating removal, deburring, and high-pressure grinding across industries such as builders hardware, medical instruments, metal fabrication, metal implants, plating and polishing, plumbing fixtures, and turbine engines.
