  1. What makes the 3M™ Cloth Belt 577F different from other cloth belts in the market?

    The 3M™ Cloth Belt 577F is made with a premium aluminum oxide mineral that gives it superior performance, durability and cut-rate over conventional abrasive grains. Its Film-lok backing system enhances belt adhesion to help reduce damages, maintain flatness and prolong its service life.

  2. Can the 3M™ Cloth Belt 577F be used on all types of surfaces?

    Yes! The abrasive belt can effectively tackle various kinds of metals, including titanium, nickel alloys, stainless steel, cobalt chrome and others. It works best for heat-sensitive applications such as heavy grinding due to its cooler cutting capability.

  3. How many pieces do I get per case when I purchase this product?

    This particular variant of the 3M™ Cloth Belts comes in a convenient pack of five units that have a dimension of about thirty-seven inches by seventy-five inches each.

Runs Cool on Heat-Sensitive Metals

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. To protect heat-sensitive alloys such as stainless steel, nickel alloys, and cobalt alloys, a grinding aid is incorporated in the belt to reduce running temperatures. 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.
