ʻO ka bit insert bit, ʻike ʻia hoʻi ʻo shallow hole drill a i ʻole U drill, he mea hana wili maikaʻi no ka hana ʻana i nā lua me ka hohonu o ka lua ma lalo o 3 mau manawa. Ua hoʻohana nui ʻia i nā ʻano mīkini mīkini CNC, nā kikowaena mīkini a me nā lathe turret i nā makahiki i hala. ma. Hoʻokomo pinepine ʻia ka drill bit me ʻelua mau mea hoʻokomo kuhikuhi e hana i nā ʻaoʻao o loko a me waho, i hana ʻia i loko o ka lua (me ke kikowaena) a me waho o ka puka (me ka paia puka), e like me ka mea i hōʻike ʻia ma ka papa ma lalo. Ke nui ka anawaena o ka puka, hiki ke hookomo i na lau he nui.
1. Hoʻohālikelike huahana Hiki ke hoʻokaʻawale ʻia ka bit insert indexable e like me ke ʻano o ka lau, ke ʻano o ka ʻohe, ke ʻano, a me nā ʻano hana.
(1) E like me ke ʻano o ka maka, hiki ke hoʻokaʻawale ʻia i kahi quadrangle, kahi huinakolu convex, daimana, hexagon, a me nā mea like.
(2) E like me ka ʻoki ʻoki maʻamau, hiki ke hoʻokaʻawale ʻia i ʻelua mau ʻano: ʻo ka ʻāʻī pololei a me ka ʻāʻī spiral.
(3) E like me ke ʻano o ka pahu drill, hiki ke māhele ʻia i ʻelua ʻano: cylindrical handle a me Morse taper bit.
(4) E like me ka hoʻolālā, hiki ke hoʻokaʻawale ʻia i ʻekolu mau ʻano: integral type, modular type a me ke poʻo ʻokiʻoki a me ke kino ʻoki ʻoki ʻano ʻano drill.
