3M Cloth Belt 577F, 6 in x 132 in 100 YF-weight Full-Flex, Case of 20

• Alumina zirconia mineral with grinding aid provides more cutting power than aluminum oxide
• Available in a range of sizes and grades to fit your specific needs
• Heavyweight cloth backing provides durability in high-production operations
• Runs cool for reliable use on heat-sensitive metals like aluminum and stainless steel
• Tough and versatile alumina zirconia mineral cuts fast and performs well on many substrates

When traditional aluminum oxide belts aren’t cutting it, try 3M Cloth Belt 577F with alumina zirconia abrasive grain. It offers increased cutting efficiency compared to aluminum oxide, and has a heavy, water-resistant polyester backing that stands up to high-pressure applications and edge work.

Runs Cool on Heat-Sensitive Metals
We recommend 3M Cloth Belt 577F for use on aluminum, mild steel, and stainless steel or 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, we incorporated a grinding aid on the belt reduces running temperatures. Additionally, 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. At 3M we offer 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.

Applications

• Deburring
• Finishing
• Grinding
• Surface preparation
