CIR phansi umgodi wokubhoboza
Isakhiwo esikhethekile sangaphakathi se-CIR uchungechunge lwe-DTH drill bits, eklanywe ngokuvumelana nethiyori yakamuva yokumba amadwala, inikeza amandla aphezulu, isivinini sokumba ngokushesha kanye nokusetshenziswa komoya okuphansi. Ngenxa yezinto zekhwalithi ephezulu ze-alloy steel nobuchwepheshe bokucubungula obuthuthukisiwe, ukusebenza kanye nempilo ende yesevisi yochungechunge lwe-CIR DTH drill bits. Ngenxa yesakhiwo sangaphakathi sesando esilula, esinokwethenjelwa, okulula ukusihlanganisa nokuhlakazwa, izinga lenkinga liphansi futhi kulula ukusinakekela. Ingashintshwa nge-DTH drill bit kanye ne-drill bit kanye nepayipi lokubhoboza.
