• 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

Trusted 3M Cloth Belt

The 3M Cloth Belt 577F offers reliable performance with alumina zirconia mineral that cuts faster than aluminum oxide. This model is designed for heavy-duty use, featuring a single-flex format that adapts well to various sanding tools.

Its Film-lok technology ensures the abrasive stays firmly bonded to the backing, making it durable under high heat and pressure. This belt is ideal for demanding metalworking tasks where consistent cutting power is needed.

Precise Size And Dimensions

This belt measures 6 inches by 48 inches, fitting many industrial belt sanders perfectly. The size allows for efficient coverage on wide belt sanders and feed-through flat finishers, smoothing rough metal edges or adding grain patterns.

Medium and narrow widths are also available in the 577F line, making it versatile for weld removal or finishing tight corners. The 6 in x 48 in size balances reach and control for various metalworking applications.

Heavyweight Durable Backing

The heavyweight cloth backing provides excellent durability in high-production operations. This backing supports the abrasive grain during tough jobs, extending belt life and maintaining performance over time.

Its water-resistant polyester construction resists wear from high-pressure use and edge work. This backing is key to the belt’s ability to handle demanding tasks without losing strength or flexibility.

Runs Cool On Metals

3M Cloth Belt 577F runs cool, making it safe for heat-sensitive metals like aluminum and stainless steel. The grinding aid reduces running temperatures, protecting delicate alloys from heat damage during grinding and finishing.

This cooling effect helps maintain metal integrity while delivering fast stock removal. It’s especially useful for dimensioning parts, deburring, blending, and finishing castings and forgings.

Case Of Twenty Belts

This product comes as a case of 20 belts, providing a ready supply for continuous industrial use. Having multiple belts on hand reduces downtime and keeps production running smoothly.

The pack size supports high-volume operations and ensures consistent availability of the 3M Cloth Belt 577F in the specified 6 in x 48 in size and Film-lok format.
