Ukuba ne-drill bit engcono kakhulu kungenza umehluko omkhulu uma kukhulunywa ngokubhoboza izinto eziqinile njengensimbi. Kunezinhlobo eziningi zama-drill bit emakethe, futhi kungaba nzima ukunquma ukuthi iyiphi engcono kakhulu ngezidingo zakho ezithile. Izinketho ezimbili ezidumile zokubhoboza insimbi ama-drill bit ambozwe nge-tin kanye nama-drill bit e-titanium nitride. Kulesi sihloko, sizohlola izici nezinzuzo zazo zombili izinhlobo zama-drill bits ukuze sikusize wenze isinqumo esinolwazi mayelana nokuthi iyiphi i-drill bit engcono kakhulu ngezidingo zakho zokubhoboza insimbi.
Ama-drill bits afakwe i-tin, aziwa nangokuthi ama-twist drill bits afakwe i-tin, aklanyelwe ukunikeza ukuqina okukhulu kanye nokumelana nokushisa lapho kubholwa insimbi. Ukwembozwa kwe-tin kusiza ukunciphisa ukungqubuzana kanye nokwakheka kokushisa ngesikhathi sokubholwa, ngaleyo ndlela kwandise impilo yokubholwa futhi kuthuthukise ukusebenza kokubholwa. Lawa ma-drill bits ngokuvamile enziwa ngensimbi yesivinini esikhulu (i-HSS) futhi afanele ukubholwa ngezinto ezifana nensimbi, i-aluminium kanye nezinye izinsimbi ezingezona i-ferrous.
Enye yezinzuzo eziyinhloko zama-drill bits asemathinini yikhono lawo lokugcina ubukhali nokusebenza kahle kokusika ngaphezu kokusetshenziswa okuningi. I-tin coating isebenza njengesithiyo esivikelayo futhi inciphisa ukuguguleka konqenqema lwe-drill. Lokhu kuphumela ekusebenzeni isikhathi eside kanye nokusebenza kahle kokubhoboza okuqhubekayo, okwenza ama-drill bits asemathinini abe ukukhetha okuthembekile kwezicelo zokusebenza kwensimbi.
Ngakolunye uhlangothi, ama-drill bits e-titanium nitride, aziwa nangokuthi ama-drill bits ane-TiN-coated, ambozwe ngesendlalelo se-titanium nitride ebusweni be-drill bit ukuze kuthuthukiswe ubulukhuni bayo kanye nokumelana nokuguguleka. Lokhu kugqoka kunikeza isiphetho segolide esingagcini nje ngokubukeka kahle, kodwa futhi kufeza injongo esebenzayo. I-titanium nitride yaziwa ngobulukhuni bayo obungavamile kanye ne-coefficient ephansi yokungqubuzana, okwenza kube ukugqoka okuhle kakhulu kwama-drill bits asetshenziswa ekushiseni insimbi nakwezinye izinhlelo zokusebenza ezidinga amandla.

Inzuzo eyinhloko yama-titanium nitride drill bits ubulukhuni bawo obungavamile, obuwavumela ukuthi agcine unqenqema olubukhali ngisho nalapho ebhoboza ngensimbi eqinile. Lokhu kwandisa isivinini sokubhoboza kanye nokusebenza kahle futhi kwandise isikhathi sokuphila kwamathuluzi. Ngaphezu kwalokho, izakhiwo eziphansi zokugoba kwe-titanium nitride zinciphisa ukushisa okukhiqizwa ngesikhathi sokubhoboza, okusiza ukuvimbela ukuguquguquka kwezingxenye zomsebenzi kanye nokwandisa isikhathi sokuphila kwama-drill bit.
Uma uqhathanisa ama-drill bits afakwe ithini kanye nama-drill bits e-titanium nitride, kubalulekile ukucabangela izidingo ezithile zomsebenzi wokubhoboza insimbi. Ilungele ukubhoboza ngenhloso evamile ezinhlobonhlobo zezinsimbi, ama-drill bits afakwe ithini anikeza ukusebenza okuthembekile nokuqina okuthembekile. Ama-drill bits e-titanium nitride, ngakolunye uhlangothi, alungele ukusetshenziswa okudinga kakhulu lapho ubulukhuni nokumelana nokuguguleka kubalulekile, njengokubhoboza insimbi eqinile noma insimbi engagqwali.
Ngaphezu kwezinto zokumboza, ukwakheka nokwakhiwa kwe-drill bit ngokwayo kudlala indima ebalulekile ekunqumeni ukusebenza kwayo kanye nokufaneleka kwayo ekubholeni insimbi. Zombili izingcezu zokubhoboza ezifakwe ithini kanye nezingcezu zokubhoboza ze-titanium nitride ziyatholakala ngezindlela ezahlukahlukene, kufaka phakathi izingcezu zokubhoboza ezisontekile, izingcezu zokubhoboza amathuluzi kanye nezingcezu zokubhoboza ezikhethekile ezenzelwe imisebenzi ethile yokusebenza ngensimbi.

Uma ukhetha i-drill bit engcono kakhulu yokubhoboza insimbi, kufanele ucabangele izici ezilandelayo:
1. Ukuhambisana kwezinto: Qiniseka ukuthi i-drill bit ifanele uhlobo oluthile lwensimbi ofuna ukuyibhoboza. Izinsimbi ezahlukene zinobunzima nezakhiwo ezahlukene, ngakho-ke kubalulekile ukukhetha i-drill bit engakwazi ukuphatha izinto ngempumelelo.
2. Ikhwalithi yokumboza: Hlola ikhwalithi kanye nobukhulu bokumboza okusebhodleleni. Ukumboza kwekhwalithi ephezulu kuzohlinzeka ngokumelana nokuguguleka okungcono kanye nokushabalalisa ukushisa, okuholela ekusebenzeni okuthuthukisiwe kanye nokuphila isikhathi eside.
3. I-geometry yokusika: Cabanga nge-geometry yokusika ye-drill, okuhlanganisa i-engeli ye-drill, ukwakheka kwe-groove kanye nesimo sayo sonke. I-geometry yokusika efanele ithuthukisa ukuphuma kwe-chip, inciphisa amandla okusika futhi ithuthukisa ukunemba kokubhoboza.
4. Uhlobo Lomgoqo: Naka uhlobo lomgoqo we-drill bit njengoba kufanele luhambisane nemishini yakho yokubhoboza. Izinhlobo ezivamile zama-shank zifaka ama-straight shanks, ama-hexagonal shanks, kanye nama-reduced bore shanks okusetshenziswa nezinhlobo ezahlukene zama-drill chucks.
5. Usayizi Nobubanzi: Khetha usayizi webhithi yokubhoboza efanele kanye nobubanzi ngokusekelwe ezidingweni zakho zokubhoboza ezithile. Ukusebenzisa usayizi ofanele kuqinisekisa usayizi wembobo ofanele futhi kuvimbela ukuguguleka okukhulu kwamathuluzi.
Ngamafuphi, ama-drill bits ambozwe nge-tin kanye nama-drill bits e-titanium nitride anikeza izinzuzo ezicacile zokubhoboza insimbi, kanti i-drill bit efanele izidingo zakho izoncika ezidingweni ezithile zomsebenzi wakho wokusebenza ngensimbi. Ama-drill bits ambozwe nge-tin ahlinzeka ngokusebenza okuthembekile nokuqina kokubhoboza insimbi okujwayelekile, kuyilapho ama-drill bits e-titanium nitride enikeza ubulukhuni obuphezulu kanye nokumelana nokuguguleka kwezicelo ezidinga kakhulu. Ngokucabanga ngezinto ezifana nokuhambisana kwezinto, ikhwalithi yokumboza, i-geometry yokusika, uhlobo lwe-shank kanye nosayizi, ungenza isinqumo esinolwazi bese ukhetha i-drill bit engcono kakhulu yemiphumela yokubhoboza insimbi esebenza kahle nenembile.
