Designed for grinding materials to final dimension, our 3M™ Trizact™ Diamond Cloth Belts 663FC can tackle hard-to-grind materials including ceramics, carbides, chilled iron and composites. They also work well for stripping old thermal spray coating during the refurbishment process. These belts cut up to 70% faster than bonded wheels – without chatter. And because they are easy to use, even less-experienced operators can achieve consistent, effective stock removal throughout the life of the belt.
3M™ Trizact™ Diamond Cloth Belts 663FC feature a waterproof YF-weight cloth backing, which means these belts can support high-pressure tough applications when run wet or dry. The abrasive side of the belt features three-dimensional structures derived from proprietary 3M technology. Unlike conventional abrasives, which are constructed from randomly-spaced and irregular-shaped minerals, Trizact abrasives feature precisely-shaped three-dimensional structures that help deliver more consistent performance and eliminate belt-to-belt variation.
