	M 42 material no. 1.3247 hardness approx. 67-69 HRC	M 51 material no. 1.3207 hardness approx. 69 HRC, with high tungsten- and cobalt content
	Flexible: The blade back of our bi-metal band saw blade consists of a special alloyed spring steel. Highly flexible at a hardness of about 50 HRC. The ideal basis for long fatique life and excellent cutting performance. Hard and wear resistant: Tooth tips made of hardened HSS Steel in M 42 or M 51 quality. Perfectly joint: Both materials are undetachably welded together. All advantages: The high quality Bi-Metal band combines the flexibility of the spring steel backing with enormeous wear resistance of high-speed steel. Each tooth tip is of hardened HSS-steel, extremely durable for best performance.
