Pachimake Core Bit
Kupanga kwa ROP wapamwamba pobowola mawonekedwe ozama komanso ovuta, kubowoleza PDC nthawi zonse kumaboola kuchokera pansi mpaka pansi mwachindunji kapena kuthamanga kamodzi, kupulumutsa nthawi yayitali ndi mtengo.
Kusiyanitsa ndi tricone bit, PDC kubowola pang'ono kumayenda ndi WOB yotsika koma RPM Yapamwamba, chifukwa chake imagwira ntchito ndi mota yotsikira kuti ikwaniritse liwiro lozungulira.
Magwiridwe a PDC kubowola pang'ono zimadalira kwambiri pa odulira PDC, timapereka yankho lapadera pazofunikira pamitundu yosiyanasiyana.
Kubowola mawonekedwe ovuta kwambiri Ndi koyenera kuti coring ikhale yovuta kwambiri, monga sandstone.
