    VKD Carbide Rock Drill Bits / Tungsten Carbide Auger Bits Trencher Bullet Teeth Rock Augers

    coal mine pdc cutters pick shape cutter tooth

    Application field

    VKD as a more than 6years history high-tech company is always concentrating on the production and research of cemented carbide.the picks we are manufacturing are used widely in the field of mining and construction etc.


    Cemented carbide:Tungsten and Cobalt

    Cemented carbide which has high hardness and toughness and high wear resistance and corrosion resistance attributes is widely used in the field of military projects,mechanical processing,metallurgy technology, oil exploiting,electronic communication etc.

    The technology and production equipment are developing unprecedented during these years along with the continuous upgrading of manufacturing industry in China and the research and innovation of new engineering material. The quality of cemented carbide of VKD is able to compete with those lending manufacturers and famous brands in the world.

    Pick for mining

    Pick are one of the quick-wear parts in the coal mine and tunnel excavation its performance decides the machine's production capacity and power consumption and working stability and the working life of other spare parts.It is the main tools which cut the coal and break coal. The popular grade of steel is 42CrMo, 35CrMnSi etc.

    The hardness of the body of pick is 40-45HRC, impact tenacity not less than 49J/cm2.

    The 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

    Our coal cutting picks bits are in all sizes, mainly used in coal mining and roadway, tunnel, the ground trenching engineering excavation, such as the main blending coal winning machine, boring machine, milling planer and other equipment.
