Indawo yesitolo sehadiwe ingaba yindawo edidayo, enezingcezu zokubhoboza ezitholakala ngezinhlobo namanani ahlukahlukene adidayo. Kwabachwepheshe kanye nabantu abathanda kakhulu izinto zokuzijabulisa, ukukhetha kubalulekile. Umehluko phakathi komsebenzi owenziwe kahle nomsebenzi owenziwe ngaphezulu uvame ukuba sekhethweni lethuluzi. Lo mhlahlandlela uhlukanisa izici ezibalulekile ezibeka izinga lobuchwephesheizingcezu zokubhola zensimbi ye-tungstenngaphandle, kugxilwe kwisayensi yezinto ezibonakalayo kanye nobuhle bokukhiqiza obuchaza bona.
Umehluko obaluleke kakhulu yizinto zokwakha. Igama elithi "insimbi ye-tungsten" (elivame ukusetshenziswa ngokushintshana nelithi "i-carbide" ngolimi oluvamile, nakuba empeleni liyi-tungsten-carbide alloy) libhekisela ezintweni ezihlanganisiwe ezaziwa ngezakhiwo zazo ezidlulele. Izinhlayiya ze-tungsten carbide zihlanganiswa ndawonye nge-cobalt matrix, okudala izinto eziqinile kakhulu kunensimbi eqinile. Lobu bunzima obuphezulu obungokwemvelo yisona sizathu esiyinhloko sokuthi lezi zingcezu zingasika izinsimbi eziqinile, amapulasitiki arhabaxa, nezinye izinto eziyinselele ezingabhubhisa ngokushesha izingcezu ezijwayelekile.
Kodwa-ke, ubulukhuni bodwa abwanele; ithuluzi kumele futhi likwazi ukumelana nokushaqeka. Inqubo yokucima ukushisa okuphezulu iyisinyathelo esibalulekile ekwelashweni kokushisa okuthuthukisa ukuqina kwe-cobalt binder, kunciphisa ukuphuka okuvame ukuhlotshaniswa nezinto eziqinile kakhulu. Le nqubo yenza kube ngcono i-bit, iyinike ukumelana okuqinile kokuguguleka impilo ende ngenkathi igcina ukuqina okwanele ukubhekana nokucindezeleka kokubhoboza ngaphandle kokuqhekeka noma ukuqhekeka.
Umklamo ubaluleke ngokulinganayo. Yiqinisoamabhithi okubhoboza ngokunembazibonakala nge-geometry yazo eqondile. I-engeli yephuzu (ngokuvamile i-118° noma i-135° yezinsimbi eziqinile) kumele igaywe ngokulingana okuphelele ukuqinisekisa ukuthi i-bit isika ngokulinganayo futhi ayidali imbobo enkulu kakhulu. Ama-flute kumele acwebezelwe kahle ukuze kuvunyelwe ama-chips ukuba aphume ngokukhululeka, kuvinjelwe ukwakheka kokushisa. I-shank eqondile kumele igxile ngokuphelele endaweni yokubhoboza; noma yikuphi ukuphambuka kubangela ukuphelelwa yisikhathi, okuholela ekudlidlizeni, ikhwalithi embi yembobo, kanye nokuguguleka okusheshayo emshinini wokubhoboza uqobo.
Okokugcina, isiqinisekiso sekhwalithi sivela enkambisweni yokukhiqiza. Isimangalo sokuhlolwa okuqinile kwe-drill bit ngayinye yilokho okuhlukanisa uhlobo oluthembekile nolungenisiwe olujwayelekile. Lokhu kusho ukuthi zonke izici ze-bit ziqinisekiswa ngokwezibalo noma zihlolwe ngo-100% kusetshenziswa izinhlelo zokulinganisa nge-laser kanye nezinye izinsimbi zokunemba. Lokhu kuzibophezela, okusekelwe kusukela ku-R&D kuya ekuhlolweni kuya efektri, kuyindlela kuphela yokuqinisekisa ikhwalithi ye-drill bit ngayinye esitokweni. Uma ukhetha i-drill bit, ukufuna lezi zinkomba ezibalulekile—izinto zensimbi ze-tungsten ezinhle kakhulu, ukugaya ngokunemba, kanye nokuzibophezela okusobala ekulawuleni ikhwalithi—kuzoqinisekisa ukuthi ukhetha ithuluzi elinikeza ukusebenza, ukuthembeka, kanye nenani lamaphrojekthi akho adinga kakhulu.
