Features and Benefits
 Bi-metal blades feature a toothed edge made from high speed steel (HSS) attached to a flexible steel backing through an electron-beam welding process. This configuration results in a blade that makes precise cuts while resisting breakage. They are used on ferrous and non-ferrous metals. 
 Toothed edge saws are composed of a row of pointed teeth. Common tooth variations include the number of teeth per inch and pitch pattern.
