ʻO TCI metal sealed bearing aila bits IADC417 no ka ʻeli hohonu ʻana i ka luawai

ʻO ka ʻāpana tricone IADC417 he ʻāpana bearing sila ʻia ʻo TCI me ka pale ana. No nā ʻano palupalu, e like me nā paʻakai a me nā pōhaku limestone, nā lepo lepo, nā pōhaku one, nā dolomites.
Loaʻa i nā ʻāpana tricone ke ʻano o ka Tungsten Carbide Insert (TCI) a me ka Mill Tooth (Steel Tooth) e like me nā mea ʻoki.
He maʻalahi lākou a hiki ke ʻoki i nā ʻano hoʻonohonoho he nui. Hoʻohana ʻia ka wili niho tricone drill bit no nā hoʻonohonoho palupalu. Hoʻohana ʻia nā TCI rotary tricone bits no nā hoʻonohonoho waena a paʻakikī. ʻO nā hoʻonohonoho pōhaku palupalu e komo pū ana me nā one i hoʻopaʻa ʻole ʻia, nā lepo lepo, nā pōhaku limestone palupalu, nā redbeds a me ka shale. ʻO nā hoʻonohonoho paʻakikī waena e komo pū ana me nā dolomites, nā pōhaku limestone, a me ka shale paʻakikī, ʻoiai ʻo nā hoʻonohonoho paʻakikī e komo pū ana me ka shale paʻakikī, ʻoiai ʻo nā hoʻonohonoho paʻakikī e komo pū ana me ka shale paʻakikī, nā pōhaku lepo, nā pōhaku limestone cherty a me nā hoʻonohonoho paʻakikī a me nā abrasive.
