Scotch-Brite™ Diamond Wheel, 645DC is a unique surface conditioning wheel containing diamond mineral for removal and pre-polishing of extra-hard materials such as carbide thermal spray and ceramics.

Made to Handle Hard-to-Grind Materials
Scotch-Brite™ Diamond Wheel, 645DC provides significant process improvements in the grinding and finishing of thermal spray and other hard-to-grind substrates. And it’s not only tough – its diamond mineral abrasive provides a consistently fine, burr-free finish throughout the life of the wheel.

Discover the Scotch-Brite™ Advantage
Nonwoven technology makes Scotch-Brite™ abrasives unique. Abrasive mineral is interspersed on synthetic fibers using resin — creating an open web construction. Spaces between the fibers permit excess material to escape, so the mineral does not become worn down by debris. It keeps the mineral cutting sharper longer, enhancing cut performance and increasing abrasive service life. The spring-like nature of the fibers works well on contours and responds to subtleties on the surface. Its responsive design effectively removes unwanted burrs, soils and contaminants without ruining the base material, so you get a consistent and uniform finish — part after part.

Typical Applications

  • Composites
  • Carbon fiber
