4" 5" 6" dth dubbe DHD 340 350 badhanka qodista
Qaybta DTH waa dhagaxa wax lagu gooyo.Sinodrills DTH xoogaa waxay ka samaysan tahay bir tayo sare leh oo uu sameeyay Timken gudaha US Ka sokow, dhammaan qaybtayada DTH waxay adeegsanaysaa summada "Element Six" TC carbide oo bixisa (badhamada TC) ee Boart Longyear.Intaa waxaa dheer tignoolajiyada wax soo saarka farshaxanku waxay ka dhigaysaa xoogaa DTH ah oo leh tayo sare oo la isku halayn karo.
Qaabka waji ee kala duwan ayaa ka dhigaya xoogaa DTH ku habboon xaaladaha dhagaxyada kala duwan.
Waji fidsan: Kani waa naqshad caalami ah, gaar ahaan samaynta dhagax adag oo xoqan.Marka sida caadiga ah, weji fidsan oo leh naqshadaynta badhamada hemi-spherical waa doorashada ugu caansan.
Wajiga Convex: Naqshad heersare ah oo loogu talagalay samaynta dhagax adag oo jilicsan iyo dhexdhexaad ah kaas oo aan ahayn mid xoqan.Naqshadeyntani waxay leedahay heerka gelitaan aad u wanaagsan laakiin way liidataa leexashada godka haddii dhagaxyadu adag yihiin.
Waji qallafsan: Dhexdhexaad adag ama qaab-dhismeedyada dhagax adag kaas oo aan xoqin oo jaban.Gaar ahaan qodista godka qoto dheer, xakamaynta fiican ee leexinta godka.
