3M™ Cloth Belt 577F, 50 YF-weight, 8-1/4 in x 100 in, Film-lok, Single-flex, 20 ea/Case

3M™ Cloth Belt 577F is a versatile abrasive belt that is ideal for dimensioning parts, deburring, blending, and finishing castings and forgings made of aluminum, mild steel, and stainless steel or other exotic metal alloys. This belt is designed to reduce running temperatures and protect heat-sensitive alloys such as stainless steel, nickel alloys, and cobalt alloys. The grinding aid incorporated in the belt helps to reduce heat buildup, while the abrasive is firmly bonded to the backing with resin to maintain durability under high heat and pressure. The alumina zirconia abrasive fractures frequently to continually produce sharp points and deliver a faster cut-rate than aluminum oxide. This synthetic mineral was developed for heavy stock removal and high-pressure grinding.

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.
