Xi'an Tydrillbits Co.,Ltd is one of the most famous China mining picks manufacturers,Website:http://www.tydrillbits.com, welcome to wholesale cheap mining picks from our factory.Description of coal mining picksThe tooth body is made of high quality cold extrusion 42CrMo, high density not decarburization. Numerical control lathe processing ensures consistent size. With special heat treatment process of 40-45 degrees, its surface is almost no oxidation, tooth head using isothermal quenching process, its hardness doesn't reduce. Production of cemented carbide by formal domestic companiesYG11C, stable quality can accord customer needs to add welding wear-resisting layer, hardness reaches more than 65 degrees.Product specificationProduct numberPick length(mm)Length of head(mm)Pick handle diameter(mm)Carbide insert diameter(mm)Pick head diameter(mm)U8215280301450U8414270301650U8516185301450U92195101351655U9418490351955U9518288352455U17021589432264We can provide customized products, if you have special requirements, please provide us the parameters of the products.Feature of coal cutting picks1) replac easily no need special tools;2) Effective against abrasion working conditions;3) In the working process don’t produce high temperature spark.We can also provide mining picks with wear-resistance and laser cladding techniqueApplication of coal cutting picksSuperior material and technology makes the cutting pick have a impact toughness and high wear resistance. Cutting teeth can’t produce high temperature spark in the working process. Thus is benefit to the safety production of coal mining. Coal cutting teeth often uses with shearer.
