Kukusiza ukuthi ubhoboze ngokushesha futhi ususe ama-shavings. Izinsimbi zokubhola i-Jobber ngokuvamile zinemitshingo ezungezayo futhi zenziwe ngensimbi ye-HSS. Lolu hlobo lwe-drill bit luhle kakhulu ekubholeni okuvamile. Ama-Jobber drill bits awabizi, okuwenza abe yinketho ekahle kubathandi be-DIY nezimfundamakhwela ezingafuni ukuchitha imali eningi kumathuluzi abangeke bawasebenzise kakhulu.
I-jobber drill bit yinde kunobubanzi bayo, okuvumela ithuluzi ukuthi libe nomtshingo owengeziwe. Ubude balo mtshingo bungaba ubude obuphindwe izikhathi ezingu-8-12 noma ezingu-9-14 kunobubanzi bayo, kuye ngokuthi yini edingekayo ohlotsheni oluthile lokubhoboza nosayizi.
Isibonelo, uma usebenzisa ama-bits angu-3/8″ ububanzi, azokwazi ukusika amafidi angaba ngu-2 kukhonkolo ngaphambi kokuphuka ngoba lezi zinsimbi zingama-intshi angu-12 ubude kodwa ziyi-intshi engu-1 kuphela ububanzi. Nakuba ezinobubanzi obungu-½”, zizojula ngama-intshi angu-6½ kuphela ngaphambi kokuphuka ngenxa yomumo wazo owumngcingo kakhulu. Uma ufuna isethi enhle futhi ehlangene, leli phakethe leNorseman Jobber Drill Bit enye ongayithola: 
Kungani Ibizwa Nge-Jobber Drill Bit?
Uma ukhuluma ngama-jobber drill bits, usho ukuthini ngokuthi “jobber”? Ubude bebhithi yokubhoboza yilokho ebhekise kukho.
Ezinsukwini zakudala, ama-drill bits ayengafiki ngamasayizi nezitayela eziningi njengoba enza namuhla. Ama-drill bits ayejwayelekile futhi ahloselwe ukusetshenziselwa izinto eziningi. “Izicucu zobude bomsebenzi” yilokho esasikubiza ngokuthi. Ubude be-Jobber bube yitemu lenhloso yonke maduze nje.
I-Jobber Drill Bit Measurement
Abasebenzi batholakala ngezinto ezihlukahlukene, abakhi kanye nosayizi. Singazikala sisebenzisa amatemu amane. Njengoba kunendlela engaphezu kweyodwa yokuchaza ububanzi noma "amayintshi" we-Jobber bits, ungase uzibuze ukuthi isifinyezo ngasinye sisho ukuthini.
Osayizi Bezingxenyekazi: i-fractional ibhekisela kumayintshi njengoba kukalwa ngamamilimitha.
Osayizi Bezinhlamvu: incwadi ikala usayizi ngamafrakshini afana no-1/16ths we-intshi.
Amasayizi we-Wire Gauge: lezi ziqala ku-1 futhi zanda ngezinombolo eziphelele.
Osayizi Bemethrikhi: amayunithi e-metric akala usayizi asebenzisa amasentimitha.
Azishintsheki ngoba izilinganiso zazo ziyehluka kuye ngokuthi zenziwa kuliphi izinga lezwe.
Yini eyenza i-Jobber Drill Bit ihluke kuma-Mechanics Drill Bits
Ama-drill bits afika ngazo zonke izinhlobo nosayizi, ngayinye inezinzuzo zayo.
Izingcezu ze-Jobber drill babe namashafu amade uma kuqhathaniswa nobubanzi bawo. Yingakho elungele ukumba izinkuni nenhlanganisela yensimbi. Inkinga nje ukuthi azikwazi ukusetshenziselwa izinsimbi eziqinile, njengoba ukuntuleka kwevolumu ngaphakathi kwalolu hlobo lwe-drill bit kungabangela ukuqhekeka.
Njengoba zizinde, zigoba kalula ezindaweni eziminyene njengezimbobo futhi azivinjwa ukwakheka kwezinto eceleni.
Izingxenye zokubhoboza zikaMechanics zingcono uma udinga ukulawula okwengeziwe lapho ubhoboza khona. I-Mechanics drill bit inobude obufushane obuphelele, kanye nomtshingo omfushane (i-shaft) oklanyelwe izindawo eziqinile lapho enkulu ingeke ilingane kahle ngenxa yokuthi ifinyelela isikhathi eside kakhulu.
Amabhithi amafushane mancane amathuba okuthi aphuke uma esetshenziswa ezintweni eziqinile njengezinsimbi eziqinile, ngenxa yekhono lawo lokumelana nokushuba.
Isetshenziswa nini i-Jobber Drill Bit
Izingcezu zokubhoboza i-jobber ezabantu abangafuni ukuthenga izinhlobo eziningi zama-drill bits. Ungenza izimbobo ezintweni eziningi, noma ngabe umba izinkuni noma insimbi ngebhithi elifanele.
Njengoba sazi ukuthi lezi zivivinyo zenzani nokuthi kungani zikhona, ingabe kufanele sizisebenzise? Ukusebenzisa le misebenzi kuzokwenza amaphrojekthi akho ansuku zonke athakazelise kakhulu kunalokho uma usebenzisa amasaha omgodi oqondile.
Njengoba lo mklamo unemiphetho eminingi yokusika, ungathwala ama-diameter ambalwa ngesikhathi esisodwa, ngakho-ke kukhona umsebenzi omncane ekugcineni okungemuva. Lawa mathuluzi ngeke abe ukuthengwa okuhle ngaphandle kokuthi usanda kungena ku-DIY noma ufuna nje okuthile okulula okufana nokubhola okuvamile.
Ama-Jobber bits aklanyelwe ukumba izimbobo ezijulile, ngakho-ke zikhethe uma ukwenza kakhulu. Kodwa kufanele wazi ukuthi izingcezu ze-jobber zinamathuba amaningi okuthi agobe noma aphuke kunezinsimbi zokubhoboza zikamakhenikha. Uma lokhu kuyinto okhathazeka ngayo, kungase kube ngcono ukuhamba nenketho emfushane.
amazwi okugcina
Ubani owayazi into elula njenge-drill bit ingaba nokusetshenziswa okuningi okuhlukene? Ziyi-bit ephelele yokusetshenziswa okuningi. Ama-Jobber bits alungele ukubhoboza izimbobo ezijulile kunezinye izingcezu. Ungakwazi futhi ukuwasebenzisa kweminye imisebenzi efana nokusika. Uma ukujula kuyingxenye yendlela yakho yansuku zonke, lokhu ukukhetha okuhlakaniphile.
Lezi zimbobo eziqinile zingasetshenziswa ukwenza izimbobo zokushayela kanye nezikulufu zokushayela. Ungase ungakuthandi uma uyi-DIYer engafuni ukuthi izingcezu zayo zinqamule noma zigobe kuphrojekthi yazo elandelayo. Noma kunjalo, izame; uzomangala ukuthi kungakanani engakwenza.
Ngingu-Joost Nusselder, umsunguli we-Tools Doctor, umakethi wokuqukethwe, kanye nobaba. Ngiyakuthanda ukuzama okokusebenza okusha, futhi kanye nethimba lami ngidale izindatshana zebhulogi ezijulile kusukela ngo-2016 ukuze ngisize abafundi abathembekile ngamathuluzi namathiphu okwenza.
