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.
Chida chothandizira kusodza chomwe chimagaya chitoliro chosakhazikika, kabokosi, kapena china chomwe chimagwera pansi pachitsime. Timagwiritsa ntchito nsapato zoboola ngati mphero kapena mphero. Ndodo. Zovala zazingwe za cylindrical zitha kugwiritsidwa ntchito kutulutsa malaya opangira gawo lobowola chingwe chobowolera.
Nsapato za diamondi zopangidwa ndi nsapato za mphero za diamondi ndizabwino ndipo zimafunikira nthawi yocheperako.
Chifukwa zidutswa ndizochepa kwambiri, pamafunika liwiro locheperako kubwerera kutsuka chitsime.
Imakhala ndi moyo wautali ndipo imatha kuchepetsa maulendo.
Chokoka chimakhala ndi pakati, osachepera atatu, koma yokwanira eyiti, malo ochepera amakona atatu. Mbali zodulira zonse kapena osachepera theka la mano athunthu akuyang'ana kumapeto kwa pang'ono. Mphepete ina iliyonse imakumana ndi chingwe chobowolera, kuti chidacho chigwiritsidwe ntchito poyenda mbali iliyonse.
Zapangidwe kuti zigwiritsidwe ntchito popanga zofewa monga mchenga, dongo kapena mitundu ina yamwala wofewa. Ndipo kukoka zidutswa zopangidwa ndi mano a tungsten carbide kumatha kupititsa patsogolo magwiridwe antchito amiyala yolimba.
