Nā Bits Drill Pōhaku Tricone niho wili:
ʻO ka niho wili (niho kila) tricone bit e wili ana no ka hoʻokumu ʻana i ka pōhaku palupalu.
Hoʻohana ʻia nā ʻāpana tricone niho wili palupalu palupalu e wili i ka ikaika compressive haʻahaʻa, hoʻokumu palupalu.Hoʻohana ʻia ka lōʻihi o nā niho projection ma nā cones offset kiʻekiʻe e hāʻawi i nā helu komo nui loa.Hoʻohana ʻia ka pale ʻana i ke alo paʻakikī no ka mālama ʻana i ke kapa niho.Ma nā ʻano bit palupalu loa, uhi ʻia kēia alo paʻakikī i nā niho bit.
Hoʻohana ʻia nā ʻāpana tricone niho liʻiliʻi no ka wili ʻana i ka ikaika compressive kiʻekiʻe, ka hoʻokumu ʻana i ka pōhaku waena.Hoʻohana ʻia nā niho projection pana me ka lōʻihi o ka crest i hōʻemi ʻia i kēia moʻo o nā hoʻolālā bit.Hoʻohana ʻia ke alo paʻa paʻa e hōʻemi i ka ʻaʻahu niho.
