Mea hoʻolako i nā bits API IADC217 8 3/4 iniha (222.2mm)

Ma muli o ka mea ʻokiʻoki, hiki ke hoʻokaʻawale ʻia nā drills tri-cone i nā drills TCI a me nā drills steel-tooth drills.

ʻO kekahi inoa ʻē aʻe no ke kila niho tri-cone drill ʻo ia ka wili niho tri-cone drill no ka mea ua hana ʻia kona mau niho e ka mīkini wili a hana ʻia ka ʻili cone me ka tungsten carbide hardfacing. ʻOi aku ka lōʻihi o nā niho ʻoi aku o ka bit tri-cone niho kila ma mua o ka bit tri-cone TCI, no laila hiki iā ia ke wili i nā hana palupalu ma ROP kiʻekiʻe.
Ma nā papahana wili ʻaila, hiki i ka ROP o ka wili pāpaʻu ke hiki i 30 mika i kēlā me kēia hola.

Me nā makahiki he 15 a ʻoi aku ma mua o 30 mau ʻāina o ka lawelawe ʻana i ka ʻenekinia wili, ua hoʻolako mākou i nā drill bits a me nā ʻuhane drilling holomua no nā noi like ʻole. ʻO kēia mau noi e pili ana i ka ʻaila hinu, ke kinoea, ka ʻimi geological, dredging, mining, water well drilling, HDD, kūkulu a me nā kumu.

No ka mea, loaʻa iā mākou kā mākou API ponoʻī a me ISO i hōʻoia ʻia i ka drill bit factory, hiki ke hoʻopilikino ʻia nā ʻāpana drill like ʻole no nā ʻano hana like ʻole. Inā hiki iā ʻoe ke hāʻawi iā mākou i nā kūlana kikoʻī e like me ka paʻakikī o ka pōhaku, ke ʻano o ka rig drilling, ka wikiwiki o ka rotation, bit weight and torque, hiki iā mākou ke hāʻawi i ka hopena o ka ʻenekinia. He mea kōkua nō hoʻi iā mākou e ʻimi i ka ʻāpana kūpono iā ʻoe ke haʻi mai ʻoe iā mākou e pili ana i ka wili kūpaʻa a i ʻole ka wili ʻana i ke aniani, ka luawai ʻaila a i ʻole ka wili ʻole a i ʻole ka pilang.
