Product Introduction
The 3M™ Cloth Belt 777F features a ceramic/aluminum oxide abrasive blend on a heavyweight polyester backing for faster cutting, longer life, and better heat resistance than standard aluminum oxide belts. With a grinding aid for stainless steel, it is suited for stock removal, deburring, blending, and finishing in both wet and dry conditions.
3M™ Cloth Belt 777F Features:
- Ceramic/aluminum oxide blend for high cut-rate and durability.
- Heavyweight polyester backing for high-pressure applications.
- Grinding aid reduces heat on heat-sensitive alloys.
- Resin bond resists heat deterioration.
- Available in various sizes and flexibilities.
3M™ Cloth Belt 777F Applications:
- Moderate stock removal on stainless steel and exotic alloys.
- Deburring and finishing metal components.
- Surface preparation before coating or welding.
- Dimensioning and blending castings or forgings.
