I-Electroplated brill yedayimane eshaywayo

I-Hole opener, eyaziwa nangokuthi i-hole saw noma i-hole saw, isho uhlobo lohlobo lwesarha olukhethekile olisebenzisa izimbobo eziyindilinga embonini yesimanje noma yobunjiniyela. Kulula ukusebenza, kulula ukuthwala, kuphephile futhi kusetshenziswa kabanzi. Lapho i-opener hole (i-cutter) ifakiwe ku-drill kagesi ejwayelekile, ingasika kalula umgodi oyindilinga, umgodi wesikwele, umgodi onxantathu, umugqa oqondile futhi ijika endizeni, indawo eyindilinga nezinye izinto ezigobekile eziphekwe ngamapuleti ahlukahlukene anjengethusi , i-iron, insimbi engagqwali ne-plexiglass.
Ngokobukhulu obuhlukahlukene bemibuthano, isisulu sokuvula umgodi sinezinto ezihlukile zokubalula nezibekiwe. Ngasikhathi sinye, ngokuya ngokujula okuhlukahlukene kokuvulwa kwembobo, ingahlukaniswa ngezinhlobo ezimbili: okuvulekile umgodi wokuvula kanye nokuvula imithwalo evulekile yomgodi. Ifakwe kumathuluzi kagesi afana nokushayela ngesandla kagesi, umthelela wokushayela kanye ne-rocker drill.
I-Hole opener
Kunezinhlobo ezimbili zobubanzi obungaguquki nobubanzi obuguquguqukayo (uhlobo lwendiza). Isixhobo esivulekile sobubanzi bomgodi sivame ukusetshenziselwa umhlobiso wangaphakathi nangaphandle.
Ukuvula umgodi obanzi okungagxiliwe okujwayelekile kunenhlobo ejwayelekile, uhlobo lomthelela kanye nohlobo lwamanzi, phakathi kwalapho uhlobo lwamanzi apholisiwe luvame ukusetshenziselwa ukuvula imbobo yomdonga, ngokusebenza kahle okuphezulu nokuvulwa kwembobo enhle.
Ngokuya ngokwezigaba ezibonakalayo: ukuvulwa kwe-bimetal hole opener, i-carbide hole opener, idayimane hole opener. Izindwangu ezahlukene zisetshenziselwa ukusika izinto ezihlukile, ezisetshenziswa kakhulu yi-bimetal hole opener, kunconywa izinsimbi zensimbi ezinzima ukusebenzisa i-alloy kanzima, ingilazi, i-carbon fiber, i-ceramics nezinye izinto ezibuthakathaka kunconywa ukusebenzisa idayimane lokuvula umgodi
