Inner Hex Body 27mm 28mm Diameter Roof Bit Coal Mining Spade Bit with Tungsten Carbide Insert
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.
