Ama-drill bits e-PDC ahlukaniswe ngezinhlobo ezimbili ngokusekelwe ezintweni zawo eziyisisekelo: Umzimba we-Matrix kanye nomzimba wensimbi, kodwa izinqubo zawo zokukhiqiza zihluke kakhulu. Ama-PDC bits omzimba wensimbi awanqunyelwe amandla emiphetho yokusika, anamandla aphezulu omqhele, amandla aphezulu okubamba amapuleti ahlanganisiwe, kulula ukuwalungisa ngemuva kokusetshenziswa, anenqubo yokukhiqiza emfushane, ukusebenza kahle kokukhiqiza okuphezulu, kanye nezindleko zokukhiqiza eziphansi, anikeza izinzuzo eziningi kune-PDC bits yomzimba we-Matrix. Ama-PDC bits omzimba we-Matrix enziwa ngokufaka ingcindezi ngaphandle kokucindezela kanye nokusila i-tungsten carbide powder ephothiwe kanye nezinto ezifaka i-inpregnating. Ukuma komzimba wokubhoboza kufezwa ngokungaqondile ngesimo sesikhunta. Isikhunta siqukethe izingxenye ezintathu: isikhunta esingezansi, isikhunta esiphakathi, kanye nesikhunta esingaphezulu. Ukwakheka kanye nokufakelwa kwesikhunta esiphakathi nesingaphezulu kulula ukukufeza. Kodwa-ke, isikhunta esingezansi siqinile esinezici eziyinkimbinkimbi zobuso obugobile. Amapharamitha womumo womqhele, isikhundla samazinyo okusika kanye nemingcele yesiqondiso, kanye namapharamitha wesakhiwo se-hydraulic se-PDC drill bit konke kufezwa ngesimo sesikhunta esingezansi. Ngakho-ke, ukwakheka kanye nokufakelwa kwesikhunta esingezansi kuyingxenye ebaluleke kakhulu yokuklama nokufakelwa kwesikhunta; Ikhwalithi yomklamo wayo kanye nokunemba komshini kuthinta ngqo ukusebenza kokugcina kwe-drill bit. Izikhunta zekhwalithi ephezulu zingenye yezinto ezibalulekile ekuqinisekiseni ikhwalithi yama-drill bit e-PDC.
Ngokusekelwe kumpendulo yamakhasimende yamanje, ama-PDC body bit ayisitayela esiyinhloko emakethe yama-PDC bit. Ngenxa yentuthuko yemboni yanamuhla, ama-PDC body bit abonisa ukusebenza okufana kakhulu nama-PDC body bit e-matrix. Ngaphezu kwalokho, ngenxa yokuthi ama-PDC body bit e-matrix abangela ukungcoliswa komoya, ama-PDC body body okwamanje abusa imakethe.
