The company's boring machine picks, coal picks, tooth shanks, tooth sets, tooth holders, S100, S120, s135, S150, S160, S170, S200 and other specifications models are complete, the steel body is selected after heat treatment of high-strength alloy steel, Maintain high strength and toughness and high wear resistance. The tooth is made of high-quality 42CrMo steel cold extrusion, high density, no decarburization. CNC lathe processing ensures consistent dimensions. The use of special heat treatment process to reach 40-45 degrees, the surface is basically no oxidation. The pick head uses an isothermal quenching process and the hardness does not decrease. Carbide adopts YG11C which is supplied by domestic regular manufacturers and has stable quality. According to the customer's needs, it can be welded with a wear-resistant layer. The hardness can reach over 65 degrees. Our main products are: Cutter-shaped picks, knife-shaped picks for mining machines, driving teeth for roadheaders, and rotary drilling rigs.
