Milled tooth Tricone Pob Zeb Laum Khoom:
Cov hniav milled (steel hniav) tricone khoom drilling rau muag muag rau nruab nrab pob zeb tsim.
Qhov muag muag milled hniav tricone khoom yog siv los laum qis compressive zog, muag muag.Ntev projection ntev ntev yog siv nyob rau hauv high offset cones los muab qhov zoo tshaj plaws penetration tus nqi.Hnav tiv thaiv lub ntsej muag tawv yog siv los tswj cov hniav hnav.Ntawm qhov softest me ntsis hom no nyuaj ntsej muag tag npog cov hniav me ntsis.
Qhov nruab nrab tsim milled hniav tricone khoom yog siv los laum siab compressive zog, nruab nrab pob zeb tsim.Tua projection hniav nrog txo crest ntev yog siv nyob rau hauv no series ntawm me ntsis designs.Lub ntsej muag tawv tawv yog siv los txo cov hniav hnav.
