CW100 is an aluminium oxide-based insert with silicon carbide whiskers (Al2O3-SiCw). When dispersed into a matrix of fine-grained aluminium oxide, these whiskers act as reinforcement, adding tensile strength and improving the fracture toughness of the brittle matrix.
According to the cutting tool manufacturer, the insert grade comes in the form of solid inserts. It is available on four insert geometries with widths of 3.175 mm, 6.35 mm and 7.925 mm.
