Ke hoʻolauna nei i ka niho DB1315 Diamond Dome DEC, ka hopena hope loa i ka ʻeli ʻana a me ke kūkulu ʻana. Hoʻolālā ʻia kēia mau niho hui daimana no ka hoʻokō ʻana i nā pono koi o nā ʻāpana cone roller, nā bits down-the-hole, nā mea hana wili ʻenehana a me nā mīkini kuʻi.
Hana ʻia nā niho DB1315 Diamond Dome DEC mai nā hiʻohiʻona kikoʻī o ka nui o nā bits PDC, me nā mea hoʻoheheʻe haʻalulu, nā niho waena a me nā niho spacer. Hāʻawi kēia mau niho i ka hana kiʻekiʻe a me ka lōʻihi, e hōʻoiaʻiʻo ana i kāu mau mea hana e hiki ke mālama i nā kūlana paʻakikī.
I nā makahiki i hala iho nei, ma muli o ka ulu mau ʻana o ka hoʻomohala ʻana o ka shale gas a me ka hoʻololi lohi ʻana o nā niho carbide, ua hoʻomau ka ulu ʻana o ka noi no nā huahana DEC. Ua alakaʻi kēia i ka manaʻo nui i ka maikaʻi, ka hana a me ka hilinaʻi o nā niho hui daimana e like me ka DB1315 daimana domed DEC niho.
Hoʻolālā ʻia nā niho DB1315 Diamond Dome DEC no ka maikaʻi loa a me ka lōʻihi, me ka nānā ʻana i ka hāʻawi ʻana i nā hana kūikawā i nā kūlana paʻakikī.
