Ma PDC drill bits amagawidwa m'magulu awiri kutengera maziko awo: Thupi la Matrix ndi Thupi la Chitsulo, koma njira zawo zopangira zimasiyana kwambiri. Thupi lachitsulo Ma PDC bits samangokhala ndi mphamvu ya m'mphepete mwa kudula, ali ndi mphamvu yayikulu ya korona, mphamvu yayikulu yolimba ya mbale zophatikizika, ndi osavuta kukonza akagwiritsidwa ntchito, ali ndi njira yochepa yopangira, magwiridwe antchito apamwamba opanga, komanso ndalama zochepa zopangira, zomwe zimapereka zabwino zambiri kuposa Matrix body PDC bits. Ma PDC bits a Matrix body amapangidwa ndi kulowetsedwa kosapanikizika komanso kusungunuka kwa ufa wa tungsten carbide wopangidwa ndi zinthu zolowetsedwa. Mawonekedwe a thupi la drill amapezeka mwanjira ina kudzera mu mawonekedwe a nkhungu. Nkhunguyo ili ndi magawo atatu: nkhungu yapansi, nkhungu yapakati, ndi nkhungu yapamwamba. Kapangidwe ndi kukonzedwa kwa nkhungu yapakati ndi yapamwamba ndikosavuta kukwaniritsa. Komabe, nkhungu yapansi ndi yolimba yokhala ndi mawonekedwe ovuta opindika pamwamba. Ma parameter a mawonekedwe a korona, malo odulira mano ndi magawo otsogolera, ndi magawo a hydraulic structure a PDC drill bit zonse zimachitika kudzera mu mawonekedwe a nkhungu yapansi. Chifukwa chake, kapangidwe ndi kukonzedwa kwa nkhungu yapansi ndiye gawo lofunika kwambiri pakupanga ndi kukonza nkhungu; Ubwino wa kapangidwe kake ndi kulondola kwa makina zimakhudza mwachindunji magwiridwe antchito omaliza a chobowolera. Zinyalala zapamwamba kwambiri ndi chimodzi mwazinthu zofunika kwambiri pakutsimikizira mtundu wa zobowolera za PDC.
Kutengera ndi ndemanga za makasitomala omwe alipo, ma PDC bits a steel body ndiye njira yayikulu pamsika wa ma PDC bit. Chifukwa cha chitukuko cha mafakitale amakono, ma PDC bits a steel body amasonyeza magwiridwe antchito omwe ali ofanana ndi ma PDC bits a matrix body. Komanso, chifukwa ma PDC bits a matrix body amayambitsa kuipitsidwa kwa mpweya, ma PDC bits a steel body pakadali pano ndi omwe akulamulira msika.
