This band saw blade consists of two materials: the tooth tips are made of alloyed HSS (high speed steel) with 10% cobalt and tungsten while the support band is made of high-alloyed spring band steel. After heat treatment, the wear-resisting tooth tips have a hardness of approx. 67 – 68 HRc. The high speed steel is connected to the support band through state-of-the-art technology.
