Nā ʻāpana niho wili IADC216 6.5 ʻīniha (165mm) no ka wili luawai

Hiki i ka Hikina Hikina ke uhi kokoke i nā code IADC a pau. ʻO ka triocne bit he wikiwiki hoʻoheheʻe wikiwiki. ʻO ka ʻōnaehana halihali hilinaʻi a me ka hana lōʻihi hiki ke mālama i ke kumukūʻai wili.
13 5/8" bit tricone niho kila
Feautre nui:
1. Ka nui mai 3 7/8" a 26".
2. Uhi kokoke i nā code IADC a pau.
3. Hoʻohana ʻia ʻo Tungsten carbide insert cutter o ka ikaika kiʻekiʻe a me ka paʻakikī e hoʻonui i ka hopena o ka hopena o nā mea ʻoki a hoʻemi i ka helu haki.
4. ʻO nā hiʻohiʻona o nā ʻāpana TCI e alakaʻi i kona hoʻokumu ʻana i nā pōhaku paʻakikī, e like me ka limestone, dolomite, chert, sandstone paʻa, anhydrite paʻa, etc.
3. Hoʻohana nui ʻia i ka ʻimi ʻaila, ka ʻimi ʻana i ka mining, ka luawai wai, ka wela ma lalo o ka honua, hydrology, etc.
3. Hiki ke hanaʻia nā'āpana e like me kāu kauoha kūikawā.
5. Loaʻa i kā mākou huahana ka maikaʻi kūpono a me ke kumukūʻai hoʻokūkū
6. Loaʻa maikaʻi nā huahana hou a hoʻohana ʻia.
