ʻO nā ʻāpana wili pōhaku niho wili API kūʻai nui i ka waihona ma muli o ke kumukūʻai haʻahaʻa loa a me ke ʻano maikaʻi loa mai ka mea hoʻolako Kina.
1) Hana ʻia ka pilina wili e like me ke kūlana API.
2) Hiki iā mākou ke hoʻoponopono i ka nui o ka bit e like me kāu rig.
3) Hiki ke loaʻa ka hopena maikaʻi loa ma ka hoʻohana ʻana i ka ʻāpana niho kila ma ka papa palupalu. Inā e ʻeli ana i ka hana paʻakikī, ua ʻōlelo ʻia ʻo TCI tricone bitis.
4) Ke hoʻomau nei nā ʻano ʻokiʻoki i hōʻoia ʻia a me nā hoʻolālā bearing i ka hāʻawi ʻana i kahi pae kiʻekiʻe o ka hana a me ka hilinaʻi.
5) Hāʻawi nā hydraulics i hoʻomaikaʻi ʻia i ka hoʻonui ʻana i ka ROP ma o ka wehe pono ʻana i nā ʻokiʻoki a me ka hōʻoia ʻana i ka hoʻopili ʻana o ka pōhaku hou ma kēlā me kēia wili ʻana o ka hale ʻokiʻoki.

ʻO ka ʻōwili cone bit ka mea hana i hoʻohana nui ʻia i ka ʻeli ʻaila a me ka ʻeli honua. Loaʻa i ka ʻōwili Tricone ka hana o ka hoʻopā ʻana, ka wāwahi ʻana a me ka ʻoki ʻana i ka pōhaku i ke kūkulu ʻia ʻana, no laila hiki iā ia ke hoʻololi i ka palupalu, waena a me ka paʻakikī. Hiki ke hoʻokaʻawale ʻia ka ʻōwili cone i ka ʻōwili cone wili (niho kila) a me ka ʻōwili cone TCI e like me ke ʻano o nā niho.
