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 .
