Deburr, Blend and Finish Stainless Steel

3M Cloth Belt 777F is specially designed to deburr, blend, and finish stainless steel and other heat-sensitive alloys. It contains a grinding aid that reduces running temperatures, making it ideal for use on stainless steel, nickel alloys, and cobalt alloys.

The abrasive grain of the belt is bonded to the backing with resin, ensuring durability even under high heat and pressure. This makes the Cloth Belt 777F perfect for dimensioning parts, deburring, blending, and finishing castings and forgings.

To enhance performance, 777F products feature a blend of aluminum oxide and 3M ceramic abrasive grain. This combination results in a harder and longer-lasting abrasive compared to traditional aluminum oxide abrasives. The ceramic/aluminum oxide blend provides superior cut-rate and durability, making the Cloth Belt 777F an excellent choice for moderate stock removal and surface preparation.

3M offers a wide range of sizes for these abrasive belts, catering to both wood and metal sanding needs. Whether you need to sand wood panels, smooth rough-cut edges of metal sheets, or add a grain pattern to stainless steel sheets, there is a belt size available for your specific application. The belts are compatible with most industrial belt sanders, ensuring a perfect fit.

Depending on your requirements, you can choose from belts with different flexibilities and splices. The 3M Cloth Belt 777F comes with a film splice, providing added strength for grinding in high-pressure applications. For increased flexibility and conformity, an L-flex belt is available. If you need the utmost flexibility, a full flex belt is the most suitable option.
