Ukwazisa ngenguqulelo ye-DB1421 idayimani yedayimani - isisombululo sokugqibela sefuthe eliphezulu kunye nokunxiba okuphezulu. Ngokukwazi ukutshintsha iimveliso ze-carbide, la mazinyo amaqela ahlala ukuya kumaxesha angama-40 ubude kune-carbide yesiqhelo yokusika amazinyo.
La mazinyo anokutsha asetyenziswe ngokubanzi kwiinkalo ezahlukeneyo, kubandakanya ukumba ubunjineli kunye nemimandla yokwakha efana ne-roller cone bits, izixhobo ze-rang-Holes-Izixhobo ze-Gepreling, kunye noomatshini bokugqobhoza. Kwaye uninzi lweenxalenye ezithile zomsebenzi ezisebenzayo ze-PDC zisetyenziswa, njengamazinyo ethusayo, amazinyo amaziko kunye namazinyo okulinganisa, kwaye la mazinyo enzayo anceda ukuguqula ishishini lokuqhuba.
Njengoko uphuhliso lwegesi shale luyaqhubeka nokukhula kwaye imfuno yamazinyo e-carbide iyancipha, imfuno ye-DB1421 idayimane yedayimane yedayisi i-chierional maines. Ngamandla abo ahlukileyo kunye nokusebenza okungapheliyo, bakhawuleza baba kukhetho lokuqala kuwo onke amashishini afuna ifuthe eliphezulu kunye nokunganyandwa kwe-arasion.
Nge-DB1421 idayimani yedayimani yedayimani, ungalindela ukuqina okugqwesileyo kunye nokuthembeka xa ukuqhuba nokumba. Ke, ukuba ufuna ukuhlala phambi kwejikajika ngokwendlela yokusebenza kakuhle kunye nokusebenza, ezi zinyongo zikuwe. Sukuhlala phantsi-khetha i-DB1421 idayimani yedayimane yedayisi namhlanje kwaye unamava umahluko!
