Runs Cool on Heat-Sensitive Metals

3M™ Cloth Belt 577F is a versatile product that is highly recommended for use on aluminum, mild steel, and stainless steel or other exotic metal alloys. It is ideal for dimensioning parts, deburring, blending, and finishing castings and forgings. The belt is designed to protect heat sensitive alloys such as stainless steel, nickel alloys, and cobalt alloys. It incorporates a grinding aid that reduces running temperatures, making it perfect for use on heat-sensitive metals. The abrasive is firmly bonded to the backing with resin to maintain durability under high heat and pressure. Alumina zirconia fractures frequently to continually produce sharp points and deliver a faster cut-rate than aluminum oxide. A synthetic mineral, it was developed for heavy stock removal and high pressure grinding.

Sized to Suit Your Needs

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. 3M offers a broad selection of belts to fit most any industrial belt sander. Wider belts are used with wide belt sanders and feed-through style flat finishers to 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 for imparting a finish. Narrow belts can be used on file tools to access right angle corners for finishing.
