Tungsten carbide powder is used to manufacture tools used in the diamond industry, such as segments, grinding wheels and scape. According to the book "Exploring Advanced Manufacturing Technologies," tungsten carbide diamond cutting tools are made by sintering diamond powder to a tungsten carbide base and then cutting them into various shapes. These shapes are inserted or brazed in tool bodies and then ground to finished shape and sizes. Diamond tools are used to cut hard materials, such as stone, glass and porcelain.
