Tungsten carbide YK05 and E6 T38 76mm T45 89mm hard rock drilling bits rods for quarry , mining drilling

1 Presentation of Rock Drilling Bits

US imports of high - quality steel and carbide manufacturing of China ' s best ,  all the threads we produce hot button drill bit technology . 

 
2 Materials and produce process details of  Rock Drilling Bits

Material  -  we use 45CrNiMoVA production of tungsten carbide and YK05 our cone drill bit ,  these two materials are world-renowned drill production materials . 

Our advanced technology  -  cone drill round thermal processing technology ,  we are currently producing a conical round diamond of the most advanced technology . 

When carbide or decreased permeability appears damaged ,  should be reground drill buttons
The fixed abrasive procedure usually leads to good working habits . 

For example ,  after checking the borehole ,  at the end of a shift or reground drill a plurality of holes .  Grinding is not necessarily too early is not economical because of less demand for grinding carbide .  The best reground ,  it will not be damaged and reduced productivity .
Correct grinding greatly increases the service life of the drill .  But equally important ,  it also improves the performance of the entire drilling operation ,  especially straightness of the hole .
