ʻO kahi ʻāpana koʻikoʻi o kahi tricone Drill Bits Design ʻo ia nā kahawai wai, me ka ʻole o ke koena o nā ʻāpana pōhaku hiki ʻole ke hana e like me ka mea i manaʻo ʻia.ʻO nā kahawai wai nā alahele no ka wai kaʻapuni, kahi e lawe mua ai i nā ʻokiʻoki i ka ʻili a hoʻomaʻemaʻe i ka hoʻokumu ʻana ma lalo o ka bit.ʻO ka hoʻolālā ʻana o nā nozzles one e kuhikuhi ana i ka wai ma ka ʻāpana ʻokoʻa ma waena o nā ʻano kahawai ʻelua:
1. nā kahawai wai maʻamau e kuhikuhi i ka wai ma luna o nā mea ʻoki
2.jet watercourses e kuhikuhi ana i ka wai i lalo o ka lua.
Holo ka wai wili mai ka Drill String a i waho ma nā nozzles i loko o ka bit.Ke hele ʻo ia ma ka ʻaoʻao o ka ʻāpana, lawe ia i ka ʻoki ʻana mai nā cones a i loko o ka annulus.ʻO ka hoʻolālā kumu no nā ʻāpana pōhaku i ʻae wale ʻia ka lepo wili e hoʻokuʻu ʻia mai ka waena o ka bit.ʻAʻole maikaʻi loa kēia a alakaʻi ʻia i ke kūkulu ʻana i nā ʻokiʻoki ma ka maka o ka bit (pōpō iki) a me ka hili ʻana o ke cone.
No laila ua hoʻokomo ʻia kahi ʻano ʻoi aku ka maikaʻi o ka hoʻomaʻemaʻe ʻana i ka maka o ka bit.Hoʻokuʻu pinepine ʻia ka wai ma o ʻekolu mau jet nozzles ma waho o ke kino bit.ʻO ka haunaele i hana ʻia e nā kahawai jet ua lawa ia e hoʻomaʻemaʻe i nā mea ʻokiʻoki a ʻae i ka hoʻomau ʻana o ka wili ʻana.
