ʻO nā ʻāpana Tricone, i kapa ʻia e kekahi poʻe ʻāpana cone wili a i ʻole ʻāpana ʻekolu-cone, he ʻekolu cones.Hiki ke hoʻololi i kēlā me kēia cone i ka wā e hoʻohuli ai ke kaula drill i ke kino o ka bit.Loaʻa i nā cones nā huila huila i hoʻokomo ʻia i ka manawa o ka hui ʻana.Hiki ke hoʻohana ʻia nā ʻoki ʻoki ʻōwili e wili i nā ʻano ʻano inā koho ʻia ka mea ʻoki kūpono, bea, a me ka nozzle.
Nā ʻāpana niho wili
1, Nā hoʻokumu palupalu (114-117)
Hoʻolālā ʻia kēia mau bits e wili i nā ʻano palupalu e like me nā shales palupalu, nā moena ʻulaʻula, a me nā pālolo, me ka lōʻihi kiʻekiʻe a me ka nui o ke komo ʻana.
2, Nā hoʻokumu palupalu a me ka waena (121,124,126,134,136,137)
Hoʻolālā ʻia kēia mau bits e wili i nā ʻano hana e like me ka shales, ka limestone palupalu, ʻo Medium sandstone a me nā ʻano hana ʻē aʻe me nā streak paʻakikī.
3, Nā hoʻokumu ʻokoʻa a paʻakikī (213,214,215,217)
Hoʻolālā ʻia kēia mau bits e wili i nā ʻano hana e like me ke one paʻa, dolomite, a me nā ʻano haʻihaʻi me nā kaha cherty paʻakikī.
