tungsten carbide drill bit,
mining drilling bits
Tungsten Carbide Tips coal mining bit / PDC double wing drill bit
Tungsten Carbide Particles: We only use the highest grade tungsten carbide as raw material for tool tips. The crushed raw material dual grain structure tungsten carbide offers high abrasive resistance.
Tungsten Carbide: The carbide raw material is pressed and sintered to produce high-quality dual grain structure tungsten carbide that has incredible we properties plus high wear resistance.
Steel Body: we are using 42crmo alloy steel, one of the highest grade of steel material. It has a hardness of up to 42-55 HRC which offers strength to the tungsten carbide tip.
Hard facing: We use specially made CR-W or chromium to make wear-resisting welded layer on the tools with the hardness of up to 55hrc-60hrc. In addition, CR-W has excellent abrasion resistance and impact resistance performance.
According to different purposes, drill bits are classified into cemented carbide bolting drill bits and PDC bolting drill bits applied to coal mining and laneway and tunnel supporting grid, PDC solid drill bits applied to coalfield geological condition and gas drainage, water injection and drainage down coal mines, and PDC non-solid drill bits applied to coalfield and geological exploration.
