I loko o ka pantheon nui o nā mea hana i hoʻopololei i ka nohona kanaka, mai ka lever haʻahaʻa a hiki i ka microchip paʻakikī, kū kekahi mea hana no kona ʻano maʻamau, maʻalahi, a me ka hopena hohonu: ʻo kaʻāpana wili wili pololeiʻO kēia ʻāpana metala cylindrical haʻahaʻa, me kona mau ʻauwaha wili i hana pono ʻia, ʻo ia ka mea hana nui o ka hana a me ka ʻākoakoa ʻana, i loaʻa i kēlā me kēia hale hana, hale hana, a me nā hale noho ma ka honua holoʻokoʻa. ʻO ia ke kī e wehe ai i ka hiki o nā mea paʻa, e ʻae ana iā mākou e hui pū, hoʻopaʻa, a hana me ka pololei i hiki ʻole ke hoʻohālikelike ʻia.
ʻOiai he hana kahiko ka hana ʻeli ʻana, mai ka wā kahiko mai me ka hoʻohana ʻana i nā pōhaku ʻoi a me nā kakaka, ʻo ka mīkini wili hou he huahana ia o ka Industrial Revolution. ʻO ka hana hou koʻikoʻi ka hoʻomohala ʻana i kāna ʻohe helical, a i ʻole ke awāwa wili. ʻO ka hana nui o kēia awāwa he ʻelua: e hoʻokahe pono i nā ʻāpana (ka mea ʻōpala) mai ka ʻaoʻao ʻoki a i waho o ka lua e ʻeli ʻia ana, a e ʻae i ka wai ʻoki e hiki i kahi e pili ai. Pale kēia i ka wela nui, hoʻemi i ka friction, a hōʻoia i kahi lua maʻemaʻe a pololei. ʻOiai hiki i nā awāwa wili ke loaʻa i 2, 3 a ʻoi aku paha nā awāwa, ʻo ka hoʻolālā 2-ʻohe ka mea maʻamau, e hāʻawi ana i kahi kaulike kūpono o ka wikiwiki ʻoki, ka wehe ʻana i nā ʻāpana, a me ka ikaika o ka bit.
ʻO ka versatility o ka straight shank twist drill bit ua hoʻopili ʻia i loko o kona inoa. ʻO ka "straight shank" e pili ana i ka hopena cylindrical o ka bit i hoʻopaʻa ʻia i loko o ka chuck o kahi mea hana. ʻO kēia hoʻolālā honua kona ikaika nui loa, e hiki ai ke kūlike me kahi pūʻulu mīkini. Hiki ke hoʻopaʻa paʻa ʻia i loko o kahi wili lima lima maʻalahi, kahi mea hana wili lima uila ikaika, a i ʻole kahi mīkini wili paʻa nui. Eia kekahi, ʻoi aku kona pono ma mua o nā lako wili i hoʻolaʻa ʻia; he ʻāpana mea hana maʻamau ia i nā mīkini wili, nā lathes, a me nā kikowaena mīkini i hoʻokele ʻia e ka kamepiula. ʻO kēia universality ka mea e lilo ai ia i lingua franca o ka honua mīkini.
ʻO ke ʻano o nā mea oʻūmiʻi wiliua hana ʻia no kāna hana. ʻO ka mea maʻamau ka High-Speed Steel (HSS), kahi papa kila hana i hana kūikawā ʻia e mālama ana i kona paʻakikī a me ka ʻoi ʻoki ʻoiai i nā mahana kiʻekiʻe i hana ʻia e ka friction. He paʻa loa nā ʻāpana HSS a kūpono hoʻi ke kumukūʻai, kūpono no ka ʻeli ʻana i ka lāʻau, ka plastic, a me ka hapa nui o nā metala. No nā noi koi loa, e like me ka ʻeli ʻana ma o nā mea abrasive e like me ka pōhaku, ka sima, a i ʻole nā metala paʻakikī loa, hoʻohana ʻia nā ʻāpana ʻeli carbide-tipped a i ʻole carbide paʻa. ʻO Carbide, kahi mea i hui pū ʻia me nā ʻāpana tungsten carbide i hoʻopaʻa ʻia me ka cobalt, ʻoi aku ka paʻakikī ma mua o HSS a hāʻawi i ke kūpaʻa ʻana i ka ʻaʻahu, ʻoiai he ʻoi aku ka palupalu.
Mai ka hōʻuluʻulu ʻana o nā ʻāpana aerospace a hiki i ka hana ʻana i nā lako hale maikaʻi, he mea hiki ke hoʻoikaika nui ʻia ka ʻūmiʻi wili shank pololei. He hōʻike ia i ka manaʻo ʻo nā hana hou i ʻoi aku ka hopena, ʻo ia ka mea e hana ana i hoʻokahi hana koʻikoʻi me ka pono kīnā ʻole. ʻAʻole ia he mea hana wale nō; ʻo ia ke kahua e kūkulu ʻia ai ka hana hou a me ka noʻeau DIY, hoʻokahi puka pololei i ka manawa.
