Izinto eziphathekayo ze-drill ziko zingahlulwa zibe yintsimbi enesantya esiphezulu, i-carbide ene-cemented, i-ceramics kunye ne-diamond ye-polycrystalline.Phakathi kwabo, isinyithi esinesantya esiphezulu siyinto esetyenziswa ngokuqhelekileyo kunye nokusebenza kweendleko eziphezulu;i-carbide ene-cemented inokumelana nokunxiba kakuhle kunye nokuqina, kwaye ifanelekile ukucubungula izinto ezinobunzima obuphezulu;i-ceramic center drill inokumelana nobushushu obuphezulu kunye nokumelana nokunxiba, kodwa ukusetyenzwa Ukusebenza kakuhle kuphantsi;i-polycrystalline diamond drill center inobulukhuni obuphezulu kunye nokumelana nokunxiba, kwaye ifanelekile ukusetyenzwa kwezinto ezinobunzima obuphezulu.Xa ukhetha izinto zokugaya iziko, kufuneka zikhethwe ngokobunzima bezinto zokusebenza kunye neemeko zokucubungula.Ngokuqhelekileyo, kwizinto ezilukhuni zetsimbi, unokukhetha izinto ezinzima, ezifana ne-cemented carbide, i-polycrystalline diamond, njl.;kwizinto ezithambileyo, unokukhetha isinyithi esinesantya esiphezulu okanye i-ceramics.Ukongeza, kuyafuneka ukuba ubeke ingqalelo kwizinto ezinjengobungakanani kunye nomgangatho womphezulu we-drill yeziko ukuze uqinisekise ukusebenza kunye nokuchaneka kokusebenza.Xa usebenzisa i-drill center, ingqwalasela kufuneka ihlawulwe ekuqhubeni i-lubrication kunye neemeko zokupholisa ukuphepha ukunxiba kwesixhobo kunye nokunciphisa umgangatho womphezulu ngenxa yokucubungula ngokugqithiseleyo.Kwangaxeshanye, kufuneka kwakhona ingqalelo ukhuseleko ngexesha processing ukuphepha ukungazinzi workpiece okanye processing iingozi ezibangelwa ukuchaneka low processing.
