Are made of imported Powder metallurgy high speed steel as teeth and imported special backer materials, the hardness can be up to 69-70HRC after heat treatment. And the tooth-shape design of positive rake angle has been optimized and upgraded, which increases the strength and wear-resistance of tooth, prolongs the blade life and extends the cutting area, making our blade is more suitable for cutting general, intractable, and wear-resistant materials or the materials¡¯ hardness above of 40HRC with high efficiency.
