Muzvishandiso zvakawanda zvakaumba budiriro yevanhu, kubva pakushandisa simba kusvika kune microchip yakaoma, chishandiso chimwe chete chinoonekwa nekuwanda kwacho, nyore, uye simba guru: iyoshank yakatwasuka yekuboorera. Chidimbu ichi chesimbi chisina kusimba, chine migero yaro inotenderera yakagadzirwa nemazvo, ndicho chinhu chikuru chekugadzira nekubatanidza, chinowanikwa mumabasa ese ekugadzira, mafekitori, uye dzimba pasi rose. Ndiyo kiyi inovhura kugona kwezvinhu zvakasimba, zvichitibvumira kubatana, kusunga, uye kugadzira nemazvo asina kuenzana.
Kunyange zvazvo chiito chekuboora chiri chekare, chichitangira munguva dzekare uchishandisa matombo akapinza neuta, chidimbu chezvino chetwist drill bit chakagadzirwa neIndustrial Revolution. Chinhu chitsva chakakosha chaive kugadzirwa kwe helical flute yayo, kana spiral groove. Basa guru re groove iyi rine zvinhu zviviri: kubvisa machipisi (marara) zvakanaka kubva pachiso chekucheka uye kubuda mugomba riri kuboorwa, uye kubvumira mvura yekucheka kusvika panzvimbo yekubata. Izvi zvinodzivirira kupisa zvakanyanya, zvinoderedza kukweshana, uye zvinoita kuti gomba rive rakachena uye rakarurama. Kunyange zvazvo spiral grooves dzichigona kuva ne 2, 3 kana kupfuura grooves, dhizaini ye 2-flute inoramba iriyo yakajairika, ichipa chiyero chakanaka chekumhanya kwekucheka, kubvisa chips, uye simba re bit.
Kugona kushandura kwe straight shank twist drill bit kwakanyorwa muzita rayo. Izwi rekuti "straight shank" rinoreva magumo e cylindrical e bit inosungirirwa mu chuck yemudziyo. Dhizaini iyi yepasi rose ndiyo simba rayo guru, zvichiita kuti ishande zvakanaka nemichina yakasiyana-siyana. Inogona kusungirirwa zvakachengeteka muchibhorani chiri nyore chemaoko, chishandiso chemagetsi chine simba chekuboorera, kana muchina mukuru wekuboorera usingachinji. Uyezve, kushandiswa kwayo kunopfuura michina yakatsaurirwa yekuboorera; ichinhu chinoshandiswa mumichina yekugaya, ma lathe, uye kunyange nzvimbo dzekugadzira dzakagadzirwa nemakombiyuta. Kushandiswa uku kunoita kuti ive mutauro wepasi rose wemichina.
Kuumbwa kwezvinhu zvechibooresoYakagadzirirwa basa rayo. Chinhu chinonyanya kushandiswa iHigh-Speed Steel (HSS), simbi yemhando yepamusoro yakagadzirwa nesimbi inoramba yakasimba uye iri nyore kushandisa kunyangwe pakupisa kwakanyanya kunokonzerwa nekukweshana. HSS bits dzakasimba uye dzinodhura zvishoma, dzakakodzera kucherwa huni, mapurasitiki, uye simbi dzakawanda. Pazvinhu zvinonyanya kushandiswa, zvakaita sekuchera zvinhu zvinorema zvakaita sematombo, kongiri, kana simbi dzakaoma kwazvo, carbide-tipped kana solid carbide drill bits dzinoshandiswa. Carbide, chinhu chakabatanidzwa chine tungsten carbide particles yakabatana ne cobalt, chakaoma kupfuura HSS uye chinodzivirira kupfeka zvakanyanya, kunyangwe chiri nyore kuputsika.
Kubva pakuungana kwezvinhu zvemuchadenga kusvika pakugadzira fenicha yakanaka, drill bit inopinza shank twist chinhu chakakosha. Izvi zvinoratidza kuti zvinhu zvitsva zvinonyanya kushanda zvakanaka ndezviya zvinoita basa rimwe chete, rakakosha uye rinoshanda zvakanaka. Harisi chishandiso chete; ndiro hwaro hwekugadzira zvinhu zvemazuva ano nehunyanzvi hweDIY hwakavakirwa, gomba rimwe chete panguva.
