Izvo zvinhu zvepakati drill zvinogona kukamurwa kuita yakakwirira-kumhanya simbi, simende carbide, ceramics uye polycrystalline diamond.Pakati pavo, high-speed simbi chinhu chinowanzoshandiswa nepamusoro pekuita mari;cemented carbide ine yakanaka kupfeka kuramba uye kuoma, uye yakakodzera kugadzira zvinhu zvine hurema hwakanyanya;ceramic centre drill ine yakanaka yakakwirira tembiricha kuramba uye kupfeka kuramba, asi kugadzirisa Kushanda kwakaderera;iyo polycrystalline diamond yepakati drill ine yakanyanya-yakanyanya kuomarara uye kupfeka kuramba, uye yakakodzera kugadzirisa yakakwirira-kuoma zvinhu.Paunosarudza iyo yepakati yekuchera zvinhu, inofanirwa kusarudzwa maererano nekuoma kweiyo workpiece zvinhu uye kugadzirisa mamiriro.Kazhinji kutaura, kune simbi yakaoma, unogona kusarudza zvinhu zvakaoma, zvakadai secemented carbide, polycrystalline diamond, nezvimwewo;nokuda kwezvinhu zvakapfava, unogona kusarudza high-speed simbi kana ceramics.Uye zvakare, zvinodikanwa zvakare kutarisisa kune zvinhu zvakaita senge saizi uye yemhando yepamusoro yepakati drill kuti ive nechokwadi chekugadzirisa mhedzisiro uye kunyatsogadzirisa.Paunenge uchishandisa chepakati chibooresa, kutarisisa kunofanirwa kubhadharwa kugadzirisa lubrication uye kutonhora mamiriro kudzivirira kupfeka kwezvishandiso uye kuderedzwa kwemhando yepamusoro nekuda kwekunyanyisa kugadzirisa.Panguva imwecheteyo, isu tinofanirawo kutarisisa kuchengetedzeka panguva yekugadzirisa kuti tidzivise kusagadzikana kweworkpiece kana tsaona dzekugadzirisa zvinokonzerwa nekuderera kwekugadzirisa.
