1、Tooth shape includes wedge-shaped tooth(X),wide top tooth(K),spon type tooth(S),conical-ended shape tooth(Y),hemi-spherical ended shape tooth(Y1),gage protection by diamond enhanced cutters on cone(F),flat diamond tooth(P).Different tooth types are selected according to different strata.
The strengthening of bits and inserts can effectively reduce the wear of tooth palms,improve the diameter protection performance of drill bits,and prolong the service life of drill bits in abrasive or directional wells or horizontal wells.
It is suitable for hard strata with high compressive strength,such as sandstone ,limestone,dolomite,anhydrite and marble. (637)
It is suitable medium hard with high compressive strength and thick&hard stringers,such as hard shale,limestone, sandstone and dolomite,etc.(617)
It is suitable medium soft with low compressive strength and harder abrasive stringers,such as hard shale,hard gypsolyte,soft limestone,sandstone and dolomite with stringers,etc.(537)
It is suitable for low compressive strength of soft ground ,such as mudstone,gypsum,salt rock,soft shale and soft limestone.(515/517)
It is suitable very soft with low compressive strength and high drillability,such as shale,clay,sandstone and conglomerate,etc.(417/437)
Packing :wooden case or iron case ,also be packaged according to customer requirements.
Modes of transportation: by sea, by air or land transportation, Of course, a small amount can also by Express.
