Kwiqela elikhulu lezixhobo eziye zabumba impucuko yoluntu, ukusuka kwi-lever ethobekileyo ukuya kwi-microchip entsonkothileyo, esinye isixhobo sibonakala ngokufumaneka kwaso ngokubanzi, ukulula, kunye nefuthe laso elinzulu:i-drill bit ethe tye ye-shank twist. Le ntsimbi ingenabugocigoci, enemigca yayo ejikelezayo eyenziwe ngokuchanekileyo, sisixhobo esisisiseko sokudala nokuhlanganisa, esifumaneka kuyo yonke indawo yokusebenzela, kumzi-mveliso, nakwimizi-mveliso kwihlabathi liphela. Sisitshixo esivula amandla ezinto eziqinileyo, esivumela ukuba sidibanise, sibophe, kwaye senze ngokuchanekileyo okungenakuthelekiswa nanto.
Nangona isenzo sokugrumba sidala, siqala kumaxesha amandulo kusetyenziswa amatye abukhali kunye neesaphetha, i-twist drill bit yanamhlanje yimveliso yoVukelo lwezoShishino. Utshintsho olubalulekileyo yayikukuphuhliswa kwe-helical flute yayo, okanye i-spiral groove. Umsebenzi oyintloko wale groove uneendlela ezimbini: ukuhambisa ii-chips (izinto ezilahliweyo) ngokufanelekileyo kude nobuso bokusika kunye nokuphuma emngxunyeni ogrutywayo, kunye nokuvumela ulwelo lokusika ukuba lufikelele kwinqanaba lokudibana. Oku kuthintela ukugqithisa, kunciphisa ukungqubana, kwaye kuqinisekisa umngxuma ococekileyo nochanekileyo. Ngelixa i-spiral grooves inokuba ne-2, 3 okanye ngaphezulu, uyilo lwe-2-flute luhlala luyinto eqhelekileyo, lubonelela ngokulinganisela okufanelekileyo kwesantya sokusika, ukususwa kwe-chip, kunye namandla e-bit.
Ukuguquguquka kwe-straight shank twist drill bit kufakwe kwi-capsule ngegama layo. Igama elithi "straight shank" libhekisa kwisiphelo esisilinda se-bit ebotshelelwe kwi-chuck yesixhobo. Olu yilo oluqhelekileyo lolona mandla alo aphezulu, olwenza ukuba ihambelane noluhlu olukhulu loomatshini. Ingabotshelelwa ngokukhuselekileyo kwi-drill elula yesandla, isixhobo esinamandla sokubhola esiphathwa ngesandla sombane, okanye umatshini omkhulu wokubhola ongashukumiyo. Ngaphezu koko, ukusetyenziswa kwayo kudlulela ngaphaya kwezixhobo zokubhola ezinikezelweyo; yinxalenye yezixhobo eziqhelekileyo kwiimashini zokusila, ii-lathes, kwanamaziko oomatshini alawulwa yikhompyutha anobuchule. Oku kufana konke kwenza kube lulwimi oluqhelekileyo lwehlabathi loomatshini.
Ukwakheka kwezinto ezisetyenzisiweyoiqhekeza lokubholayenzelwe umsebenzi wayo. Eyona nto ixhaphakileyo yiHigh-Speed Steel (HSS), uhlobo olukhethekileyo lwentsimbi yesixhobo egcina ubulukhuni bayo kunye nomgangatho wayo ophambili nokuba kumaqondo obushushu aphezulu abangelwa kukungqubana. Iibhithi zeHSS zihlala ixesha elide kwaye zingabizi kakhulu, zifanelekile ukugqobhoza imithi, iplastiki, kunye neentsimbi ezininzi. Kwizicelo ezifuna kakhulu, njengokugqobhoza izinto ezirhabaxa ezifana nelitye, ikhonkrithi, okanye iintsimbi eziqinileyo kakhulu, kusetyenziswa iibhithi zokugqobhoza ezineencam zekhabhide okanye eziqinileyo. ICarbide, into edityanisiweyo equlethe amasuntswana ekhabhide ye-tungsten ebotshelelwe kwi-cobalt, inzima kakhulu kuneHSS kwaye inika ukumelana nokuguguleka okuphezulu kakhulu, nangona ikwabuthathaka ngakumbi.
Ukususela ekuhlanganiseni izinto zeenqwelo-moya ukuya ekwenzeni ifenitshala entle, i-straight shank twist drill bit iyinto efunekayo. Bubungqina bengcamango yokuba izinto ezintsha ezinefuthe kakhulu zihlala zizinto ezenza umsebenzi omnye obalulekileyo ngokusebenza kakuhle. Ayisiyonto nje isixhobo; sisiseko apho kwakhiwa khona ukwenziwa kwezinto zanamhlanje kunye nobuchule be-DIY, umngxuma omnye ochanekileyo ngexesha.
