Ke hoʻolauna nei i ka niho DB1315 Diamond Dome DEC, ka hopena hope loa i ka ʻeli ʻana a me ke kūkulu ʻana i hana ʻia. Ua hoʻolālā ʻia kēia mau niho hui daimana e hoʻokō i nā pono koi o nā ʻāpana cone roller, nā ʻāpana down-the-hole, nā mea hana ʻeli ʻenekinia a me nā mīkini wili.
Hana ʻia nā niho DB1315 Diamond Dome DEC mai nā hiʻohiʻona kikoʻī o kekahi mau ʻāpana PDC, me nā mea hoʻopau haʻalulu, nā niho waena a me nā niho spacer. Hāʻawi kēia mau niho i ka hana kiʻekiʻe loa a me ke kūpaʻa, e hōʻoiaʻiʻo ana e hiki i kāu lako ke hoʻokele i nā kūlana paʻakikī loa.
I nā makahiki i hala iho nei, ma muli o ka ulu mau ʻana o ka hoʻomohala ʻana o ke kinoea shale a me ka hoʻololi mālie ʻana o nā niho carbide, ua hoʻomau ka ulu nui ʻana o ke koi no nā huahana DEC. Ua alakaʻi kēia i ka hoʻonui ʻia ʻana o ka nānā ʻana i ka maikaʻi, ka hana a me ka hilinaʻi o nā niho composite daimana e like me nā niho DEC dome daimana DB1315.
Ua hoʻolālā ʻia nā niho DB1315 Diamond Dome DEC no ka pono a me ke kūpaʻa kiʻekiʻe loa, me ka nānā ʻana i ka hāʻawi ʻana i ka hana kūikawā i nā kūlana paʻakikī. Hana ʻia lākou me nā mea hana kiʻekiʻe a me ka hana ʻana e hōʻoia i hiki iā lākou ke kū i nā ʻano ʻino loa a hoʻomau i ka hana ma ke kiʻekiʻe loa.
No laila, inā ʻoe e ʻimi nei i kahi niho hui daimana hana kiʻekiʻe e hiki ke lawelawe i nā kahua paʻakikī loa o ka ʻeli ʻenekinia a me ke kūkulu ʻana, mai nānā hou aku ma mua o ka niho DEC dome daimana DB1315. Me kā lākou hana kiʻekiʻe a me ke kūpaʻa, ʻo ia ka hopena kūpono no nā noi koi.
