Ke hoʻolauna nei i ka niho spherical spherical DB1421 kipi - ka hopena hope loa no ka hopena kiʻekiʻe a me ke kūpaʻa ʻaʻahu kiʻekiʻe. Me ka hiki ke hoʻololi 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, e like me ka ʻeli ʻenekinia a me nā kahua kūkulu e like me nā pahu pahu pahu pahu, nā bits drill down-the-hole, nā mea hana wili ʻenekinia, a me nā mīkini kuʻi. A nui nā ʻāpana hana kikoʻī o nā bits PDC e hoʻohana ʻia, e like me nā niho hoʻohāhā, nā niho waena a me ke ana ʻana i nā niho, a ke kōkua nei kēia mau niho hui e hoʻololi i ka ʻoihana wili.
Ke hoʻomau nei ka ulu ʻana o ka shale gas a me ka emi ʻana o ka noi no nā niho carbide, ke ulu nei ka noi no DB1421 daimana spherical composite niho. Me ko lākou ikaika ʻokoʻa a me ka hana lōʻihi, ke lilo wikiwiki nei lākou i koho mua ma nā ʻoihana āpau e koi ana i ka hopena kiʻekiʻe a me ke kūpaʻa abrasion.
Me ka DB1421 Diamond Spherical Compound Teeth, hiki iā ʻoe ke manaʻo i ka paʻa maikaʻi a me ka hilinaʻi i ka wā e wili ai a eli. No laila, inā makemake ʻoe e noho ma mua o ka pihi ma ke ʻano o ka pono a me ka hana, ʻo kēia mau niho kohu no ʻoe. Mai hoʻopaʻa i ka liʻiliʻi - koho i ka DB1421 Diamond Spherical Compound Teeth i kēia lā a ʻike i ka ʻokoʻa!
