Iibhithi zokubhola zePDC zahlulwe zibe ziintlobo ezimbini ngokusekelwe kwizinto ezisisiseko: Umzimba weMatrix kunye nomzimba weNsimbi, kodwa iinkqubo zazo zokwenza zahluke kakhulu. Iibhithi zePDC zomzimba wentsimbi azithintelwanga ngamandla emiphetho yokusika, zinamandla aphezulu esithsaba, amandla aphezulu okugquma iipleyiti ezidityanisiweyo, kulula ukuzilungisa emva kokusetyenziswa, zinenkqubo yemveliso emfutshane, ukusebenza kakuhle kwemveliso, kunye neendleko zemveliso eziphantsi, zibonelela ngeenzuzo ezingaphezulu kuneebhithi zePDC zomzimba weMatrix. Iibhithi zePDC zomzimba weMatrix zenziwe ngokufaka i-pressureless nokukhupha i-tungsten carbide powder kunye nezinto zokufunxa. Imilo yomzimba wokufunxa ifezekiswa ngokungathanga ngqo ngokuma kwe-mold. I-mold inamacandelo amathathu: i-mold esezantsi, i-mold ephakathi, kunye ne-mold ephezulu. Uyilo kunye nokufunxa ii-mold eziphakathi neziphezulu kulula ukuzifumana. Nangona kunjalo, i-mold esezantsi yinto eqinileyo eneempawu zomphezulu ezintsonkothileyo. Iiparameter zesimo sesithsaba, indawo yamazinyo okusika kunye neeparameter zesikhokelo, kunye neeparameter zesakhiwo se-hydraulic se-PDC drill bit zonke zifezekiswa ngokuma kwe-mold esezantsi. Ke ngoko, uyilo kunye nokufunxa i-mold esezantsi yeyona nxalenye ibalulekileyo yoyilo kunye nokufunxa i-mold; Umgangatho woyilo lwayo kunye nokuchaneka komatshini wokugaya kuchaphazela ngokuthe ngqo ukusebenza kokugqibela kwe-drill bit. Ii-molds ezikumgangatho ophezulu zezinye zezinto ezibalulekileyo ekuqinisekiseni umgangatho wee-PDC drill bits.
Ngokusekelwe kwingxelo yabathengi yangoku, ii-PDC body bits zezona zinto ziphambili kwimarike yee-PDC bit. Ngenxa yophuhliso lweshishini lanamhlanje, ii-PDC body bits zentsimbi zibonisa ukusebenza okufana nee-PDC body bits ze-matrix body. Ngaphezu koko, ngenxa yokuba ii-PDC body bits ze-matrix body zibangela ungcoliseko lomoya, ii-PDC body bits zentsimbi ngoku zilawula imarike.
