Njengezingcezu ezimbili zokubhola ezisetshenziswa kakhulu zezinto ezahlukene, izingcezu zokubhola zensimbi ezisheshayo kanye Izingcezu zokubhoboza ze-carbide, yiziphi izici zazo, yiziphi izinzuzo nezinkinga zazo, nokuthi iyiphi impahla engcono uma iqhathaniswa.
Isizathu sokuthi ama-drill bit ensimbi esheshayo asetshenziswa kabanzi ukuthi izinto zensimbi zesivinini esiphezulu zinamandla okumelana nokushisa okuphezulu kanye nokumelana nokuguguleka, futhi ngeke zikhiqize ukuguquguquka kanye nemiphumela yokuguguleka ngesikhathi sokusika izinga lokushisa eliphezulu. Yiqiniso, kuqinisekiswa kancane kancane ngokusetshenziswa kwesikhathi. Kuzoba nokulahlekelwa, kodwa izinto ezenziwa ngesikhathi ngaphandle kokuchitha isikhathi zibaluleke kakhulu. Okwesibili, ukuqina kwama-drill ensimbi yesivinini esiphezulu kuphakeme kakhulu kunokwezinye izinto. Ama-drill drill akumele agcine nje kuphela izidingo zokuqina nokuqina. Futhi aphezulu kakhulu. Ngaphandle kokuqina okuhle, i-drill bit ithambekele ekuqhekekeni, okuholela kububanzi bembobo obungazinzile lapho i-drill bit igugile.
Inzuzo enkulu yama-carbide drill ubulukhuni bawo obuphezulu. Inzuzo yobulukhuni obuphezulu ivumela ama-carbide drill ukuthi abhekane nezinye izinsimbi eziningi ezinobulukhuni obuphezulu. Kodwa-ke, ububi obukhulu bama-carbide drill ubulukhuni obubi, obuqhekeka kakhulu futhi kulula ukubuqhekeza. Endabeni yemigodi ejulile, uma kungekho nqubo ekhethekile njenge-support carbide drill bit ikude nomphumela we-high-speed steel drill bit, vele, ubulukhuni be-high-speed steel drill bit bungamelana nayo.
Ngokuvamile, ama-drill bits ensimbi anejubane eliphezulu kanye nama-drill bits e-carbide anezimpawu ezifanayo, kodwa iphuzu elivelele lensimbi enejubane eliphezulu lisebuqineni obuhle, kuyilapho iphuzu elivelele lama-drill bits e-carbide bubulukhuni obuphezulu, kanti umehluko wezinkinga ukuthi ubulukhuni bama-drill bits ensimbi anejubane eliphezulu abwanele, futhi insimbi enobunzima obukhulu iyacutshungulwa.
Ayikwazi ukumelana nokuguguleka, futhi ukuqina kwama-carbide drill okucubungula imigodi ejulile akukuhle, ngakho-ke lapho ukhetha i-drill, kufanele ukhethe i-drill ehambisanayo ngokwesimo esithile. Isibonelo, ama-drill ensimbi asheshayo enziwe ngethusi, insimbi kanye ne-aluminium afaneleka kakhulu kune-carbide drill. I-DTH high-hardness carbide drill bit izohlala isikhathi eside kune-drill steel drill bit yesivinini esikhulu.
