Diamond tipped circular saw blades are specialist tools used primarily in construction work. A diamond blade is made up of two basic elements, a circular sheet steel and a diamond impregnated segment, which is a mixture of diamond grains and powdered metal. There are a few processes that are able to bind the rim securely to the steel such as brazing, laser welding and sintering. The diamonds used in the manufacture of the saw blades are industrial diamonds of different sizes and qualities depending on the material to be cut.
