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.

One of the key features of 777F products is the use of ceramic abrasive grain blended with aluminum oxide. 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 the Cloth Belt 777F to suit various sanding needs. Whether you are sanding wood or metal, there is a belt size available for you. Wider belts are used with wide belt sanders for dimensioning or finishing wood panels, smoothing rough-cut edges of metal sheets, or adding a grain pattern to stainless steel sheets. Medium-width belts are designed for edge sanders, perfect for sanding flat and narrow surfaces such as panel edges. Narrow belts are used with portable belt sanders for sanding or blending wood pieces like cabinet doors.

When it comes to flexibility and splices, 3M Cloth Belt 777F offers different options. The belt comes with a film splice for added strength when grinding in high-pressure applications. For increased flexibility and conformity, an L-flex splice is available. And if you need the most flexible belt, the full flex belt is the perfect choice.
