I-HSS, ebizwa ngokuthi insimbi esheshayo, iyinsimbi yamathuluzi equkethe ama-alloy afana ne-chromium, i-tungsten, ne-vanadium. Lezi zithasiselo zandisa ubulukhuni, amandla, kanye nokumelana nokushisa kwe-drill, okuvumela ukuthi isike insimbi kahle kakhulu. Ukusebenza kwayo okuphezulu kuthuthukiswa kakhulu ukwakheka kwayo kwe-groove esontekile, okuqinisekisa ukuphuma kwe-chip, kunciphisa ukwakheka kokushisa futhi kuholele ekhwalithini engcono yemigodi.
Esinye sezici ezivelele zama-HSS twist drill bits ensimbi ukuthi asebenza ngezindlela eziningi. Angasetshenziswa ezinhlobonhlobo zezicelo, kusukela ekucubungulweni kwensimbi okuyisisekelo kuya kumaphrojekthi ezimoto, ezindiza kanye nokwakha. Kungakhathaliseki ukuthi ukubhoboza imigodi yokuhlola, ukwandisa imigodi ekhona, noma ukudala imicu eqondile, la ma-drill bits enza umsebenzi uphele kalula.
Ngaphezu kwalokho, ama-HSS twist drill bits atholakala ngobude obuhlukahlukene, ububanzi kanye nama-tip engeli ukuze kuhlangatshezwane nezidingo ezahlukene. Isibonelo, i-drill bit emfushane ene-angle yamaphuzu angu-135 ilungele ukubhoboza insimbi eqinile, kanti i-drill bit ende ilungele ukubhoboza imigodi ejulile. Lokhu kuguquguquka kuvumela onjiniyela nabadwebi ukuthola ithuluzi elifanele izidingo zabo ezithile, ukuqinisekisa imiphumela enembile nephumelelayo njalo.
Ukuqina kungenye into ebalulekile ehlukanisa ama-drill bits e-HSS twist ahlukene nomncintiswano. Ngenxa yokwakhiwa kwawo kwensimbi okusheshayo kanye nama-alloy akhethekile, la ma-drill bits angamelana namazinga okushisa aphezulu akhiqizwa ngesikhathi sokubhoboza insimbi. Lokhu kuwenza angagugi kalula, okwandisa kakhulu impilo yawo yesevisi ngenkathi egcina ukusebenza kwawo kokusika. Ngakho-ke, ochwepheshe bangathembela kula ma-drill bits isikhathi eside ngaphandle kokubeka engcupheni ikhwalithi.
Ama-drill bits ensimbi eshesha kakhulu aletha imiphumela emihle kakhulu uma kukhulunywa ngokuqinisekisa ukunemba. Umklamo wayo obukhali wokusika kanye nomklamo we-spiral flute uvumela ukubhoboza okuhlanzekile nokunembile. Lokhu kubalulekile ekusetshenzisweni lapho ubukhulu obuqondile bubalulekile, njengalapho kwakhiwa imigodi enezintambo yezikulufo noma amabhawodi. Ngalezi zibhobozo, onjiniyela bangafinyelela ukubekezelelana okuqinile, banciphise noma yikuphi ukushintshwa okungenzeka, futhi ekugcineni bonge isikhathi nomzamo.
Imakethe yama-drill bits ensimbi asheshayo asontayo ezinsimbi ikhula ngokushesha njengoba isidingo sokwakhiwa nokucubungula okuseqophelweni eliphezulu siqhubeka nokukhula. Abakhiqizi abahamba phambili bayaqhubeka nokusungula izinto ezintsha ukuze bahlangabezane nezidingo ezihlala zishintsha zonjiniyela nabachwepheshe. Ezinye izinkampani zethula upende oluthuthukisiwe ukuze zithuthukise ukusebenza komgodi, kanti ezinye zakha amajiyometri amasha ukuze zithuthukise ukuphuma kwama-chip futhi zinciphise amandla okusika.
Ngamafuphi, ama-HSS twist drill bits ensimbi aguqula imboni yobunjiniyela bokunemba ngokuhlanganisa ukuqina, ukuguquguquka kanye nokunemba. Ngokwakhiwa kwawo kwensimbi okusheshayo, angasika izinhlobo ezahlukene zensimbi kalula, okwenza zibe ithuluzi elibalulekile kochwepheshe. Njengoba le makethe iqhubeka nokukhula, intuthuko yezobuchwepheshe izothuthukisa ukusebenza kwala ma-drill bits, iqinisekise imiphumela ethembekile futhi isunduze imingcele yobunjiniyela bokunemba.
