Ukuba ne-drill bit engcono kunokwenza umahluko omkhulu xa kufikwa ekubholeni kwizinto eziqinileyo ezifana nesinyithi. Kukho iintlobo ezininzi zee-drill bits ezithengiswayo, kwaye kunokuba nzima ukufumanisa ukuba yeyiphi efanelekileyo kwiimfuno zakho ezithile. Iindlela ezimbini ezidumileyo zokubholiza isinyithi zii-drill bits ezigqunywe ngetin kunye nee-titanium nitride drill bits. Kweli nqaku, siza kuhlola iimpawu kunye neenzuzo zazo zombini ezi ntlobo zee-drill bits ukukunceda wenze isigqibo esinolwazi malunga nokuba yeyiphi i-drill bit efanelekileyo kwiimfuno zakho zokubholiza isinyithi.
Iibhithi zokubhola ezifakwe i-tin, ezaziwa ngokuba ziibhithi zokubhola ezijijekileyo nge-tin, zenzelwe ukubonelela ngokuqina okukhulu kunye nokumelana nobushushu xa kubhola isinyithi. Ukwaleka kwe-tin kunceda ukunciphisa ukungqubana kunye nokwakheka kobushushu ngexesha lokubhola, ngaloo ndlela kwandisa ubomi bokubhola kunye nokuphucula ukusebenza kokubhola. Ezi bhithi zokubhola zihlala zenziwe ngentsimbi ekhawulezayo (HSS) kwaye zifanelekile ukubhola ngezinto ezifana nentsimbi, i-aluminium kunye nezinye iintsimbi ezingezizo i-ferrous.
Enye yezona nzuzo ziphambili zeebhithi zokubhola ezifakwe kwiitini kukukwazi kwazo ukugcina ubukhali kunye nokusebenza kakuhle kokusika phezu kokusetyenziswa okuninzi. Ingubo yetini isebenza njengomqobo wokukhusela kwaye inciphisa ukuguguleka komphetho wokusika wedrill. Oku kubangela ukuba ihlale ixesha elide kwaye isebenze ngokuqhubekayo ekubholeni, okwenza iibhithi zokubhola ezifakwe kwiitini zibe lukhetho oluthembekileyo kwizicelo zokusebenza ngentsimbi.
Kwelinye icala, ii-titanium nitride drill bits, ezaziwa ngokuba zii-TiN-coated drill bits, zigqunywe ngomaleko we-titanium nitride kumphezulu we-drill bit ukomeleza ubulukhuni bayo kunye nokumelana nokuguguleka kwayo. Olu gqunywe lubonelela ngokugqitywa kwegolide okungabukeki kukuhle kuphela, kodwa kukwasebenza nenjongo esebenzayo. I-titanium nitride yaziwa ngobulukhuni bayo obugqwesileyo kunye ne-coefficient ephantsi yokungqubana, okwenza ukuba ibe lugqunywe olufanelekileyo lwee-drill bits ezisetyenziswa kwi-mechanical metal kunye nezinye izicelo ezifuna amandla.

Eyona nzuzo iphambili yeebhithi ze-titanium nitride drill bubulukhuni bazo obungaqhelekanga, obuzivumela ukuba zigcine umphetho obukhali wokusika nokuba zigqobhoza ngentsimbi eqinileyo. Oku kwandisa isantya sokugqobhoza nokusebenza kakuhle kwaye kwandisa ubomi besixhobo. Ukongeza, iipropati zokungqubana okuncinci kwengubo ye-titanium nitride zinciphisa ubushushu obuveliswa ngexesha lokugqobhoza, zinceda ukuthintela ukuguquguquka kwento yokusebenza kunye nokwandisa ubomi beebhithi ze-drill.
Xa kuthelekiswa iibhithi zokubhola ezifakwe itini kunye neebhithi zokubhola ze-titanium nitride, kubalulekile ukuqwalasela iimfuno ezithile zomsebenzi wokubhola ngesinyithi. Ilungele ukubhola ngokubanzi kwiintlobo ngeentlobo zeesinyithi, iibhithi zokubhola ezifakwe itini zibonelela ngokusebenza okuthembekileyo kunye nokuqina. Iibhithi zokubhola ze-titanium nitride, kwelinye icala, zilungele ukusetyenziswa okudinga kakhulu apho ubunzima kunye nokumelana nokuguguleka kubaluleke kakhulu, njengokubhola ngentsimbi eqinileyo okanye intsimbi engatyiwayo.
Ukongeza kwizinto zokugquma, uyilo kunye nokwakhiwa kwe-drill bit ngokwayo kudlala indima ebalulekileyo ekumiseleni ukusebenza kwayo kunye nokufaneleka kwayo ekubholeni ngesinyithi. Zombini ii-drill bits ezifakwe i-tin plated kunye nee-titanium nitride drill bits ziyafumaneka ngeendlela ezahlukeneyo, kubandakanya ii-twist drills, ii-tool drills kunye nee-specialty drills ezenzelwe imisebenzi ethile yokusebenza ngesinyithi.

Xa ukhetha i-drill bit efanelekileyo yokubhola isinyithi, kufuneka uqwalasele ezi zinto zilandelayo:
1. Ukuhambelana kwezinto: Qinisekisa ukuba i-drill bit ifanelekile kuhlobo oluthile lwesinyithi ofuna ukusigrumba. Iintsimbi ezahlukeneyo zinobunzima kunye neempawu ezahlukeneyo, ngoko ke kubalulekile ukukhetha i-drill bit ekwaziyo ukusingatha izinto ngokufanelekileyo.
2. Umgangatho wokugquma: Vavanya umgangatho kunye nobukhulu bokugquma okukwi-drill. Ukugquma okusemgangathweni ophezulu kuya kubonelela ngokumelana nokuguguleka okungcono kunye nokusasazeka kobushushu, okukhokelela ekusebenzeni ngcono kunye nexesha elide.
3. Ijiyometri yokusika: Cinga ngejiyometri yokusika yedrill, kubandakanya i-engile yokubhola, uyilo lomngxuma kunye nemilo iyonke. Ijiyometri yokusika efanelekileyo iphucula ukuphuma kweetshiphusi, inciphisa amandla okusika kwaye iphucula ukuchaneka kokubhola.
4. Uhlobo lweShank: Nika ingqalelo kuhlobo lweshank ye-drill bit njengoko kufuneka ihambelane nezixhobo zakho zokubhola. Iintlobo eziqhelekileyo zeshank ziquka i-straight shanks, i-hexagonal shanks, kunye ne-reduced bore shanks ezisetyenziselwa iintlobo ezahlukeneyo ze-drill chucks.
5. Ubungakanani kunye nobubanzi: Khetha ubungakanani kunye nobubanzi be-drill bit obufanelekileyo ngokweemfuno zakho zokubhola. Ukusebenzisa ubungakanani obuchanekileyo kuqinisekisa ubungakanani obufanelekileyo bomngxuma kwaye kuthintela ukuguguleka okugqithisileyo kwezixhobo.
Ngamafutshane, iibhithi zokubhola ezigqunywe ngetin kunye neebhithi zokubhola ze-titanium nitride zibonelela ngeenzuzo ezicacileyo zokubhola isinyithi, kwaye ibhithi yokubhola efanelekileyo kwiimfuno zakho iya kuxhomekeka kwiimfuno ezithile zomsebenzi wakho wokusebenza ngesinyithi. Iibhithi zokubhola ezigqunywe ngetin zibonelela ngokusebenza okuthembekileyo kunye nokuqina kokubhola isinyithi ngokubanzi, ngelixa iibhithi zokubhola ze-titanium nitride zibonelela ngobunzima obuphezulu kunye nokumelana nokuguguleka kwizicelo ezifuna kakhulu. Ngokuqwalasela izinto ezinje ngokuhambelana kwezinto, umgangatho wokugquma, ijiyometri yokusika, uhlobo lwe-shank kunye nobukhulu, ungenza isigqibo esinolwazi kwaye ukhethe ibhithi yokubhola engcono ukuze ufumane iziphumo zokubhola isinyithi ezichanekileyo nezisebenzayo.
