 Coal miner pick pick pick pick spade 
 Uses: mainly used for coal mining and tunnel, tunnel, ground trenching and other excavation projects. Mainly equipped with shearer, boring machine, milling machines and other equipment. 
 Pick model mainly based on the hardness of coal mining, by factors such as tooth type seat, pick divided into: U62, U82, U84, U92, U94, U95, U765 and other models, if any, quantitative production of special models. Tooth body is made of high-quality cold extrusion 42CrMo steel, high density, non-decarburization. CNC lathe to ensure the same size. Using a special heat treatment process, to 40-45 degrees, almost no oxidation of the surface. Cutter head by isothermal quenching, the hardness is not reduced. Carbide produced by domestic manufacturers formal YG11C, quality and stability. Welding according to customer needs additional wear layer. Hardness of 65 degrees.
