Ke hoʻolauna nei i ka niho hui poepoe daimana DB1421 kipi - ʻo ia ka hopena hope loa no ka hopena kiʻekiʻe a me ke kūpaʻa kiʻekiʻe o ka ʻaʻahu. Me ka hiki ke pani i nā huahana carbide, ʻoi aku ka lōʻihi o kēia mau niho composite a hiki i 40 mau manawa ma mua o nā niho ʻoki carbide kuʻuna.
Hoʻohana nui ʻia kēia mau niho hou i nā ʻano like ʻole, me nā ʻoihana ʻeli ʻenekinia a me nā kahua kūkulu e like me nā ʻāpana roller cone, nā ʻāpana drill down-the-hole, nā mea hana wili ʻenekinia, a me nā mīkini wili. A hoʻohana ʻia ka nui o nā ʻāpana hana kikoʻī o nā ʻāpana PDC, e like me nā niho hoʻopūhoihoi, nā niho waena a me nā niho ana, a ke kōkua nei kēia mau niho hui i ka hoʻololi ʻana i ka ʻoihana wili.
I ka hoʻomau ʻana o ka ulu ʻana o ke kinoea shale a me ka emi ʻana o ke koi no nā niho carbide, ke piʻi nui nei ke koi no nā niho composite spherical diamond DB1421. Me ko lākou ikaika kūikawā a me ka hana lōʻihi, ke lilo koke nei lākou i koho mua ma nā ʻoihana āpau e koi ana i ke kūpaʻa kiʻekiʻe i ka hopena a me ka abrasion.
Me nā niho hui ʻāpana Diamond Spherical DB1421, hiki iā ʻoe ke manaʻo i ka lōʻihi a me ka hilinaʻi maikaʻi loa i ka wā e ʻeli ai a eli ana. No laila, inā makemake ʻoe e noho ma mua o ke kaʻina ma ke ʻano o ka pono a me ka hana, ʻo kēia mau niho hui nou. Mai noho no ka mea liʻiliʻi - e koho i nā niho hui ʻāpana Diamond Spherical DB1421 i kēia lā a ʻike i ka ʻokoʻa!
