He pōkole ka code IADC no "International Association of Drilling Contractors".
ʻO ka IADC Code no Tricone Bits e wehewehe i kona hoʻolālā ʻana a me nā hiʻohiʻona hoʻolālā ʻē aʻe (SHIRT TAIL, LEG, SECTION, CUTTER).
He mea maʻalahi nā IADC Codes i ka poʻe drillers e wehewehe i ke ʻano o ka bit rock a lākou e ʻimi nei i ka mea hoʻolako.
ʻO Far Eastern ka hahai ʻana i ka ʻōnaehana hoʻokaʻawale bit IADC kahi e hoʻokaʻawale ai nā huahelu mua ʻekolu i ka bit e like me ke ʻano i hoʻolālā ʻia e wili a me ka hoʻolālā bearing/seal i hoʻohana ʻia.
ʻO ka wehewehe code IADC no ka huahelu mua:
Koho ʻo 1,2, a me 3 i nā ʻāpana niho kila me ka 1 no ka palupalu, 2 no ka waena a me ka 3 no ka hana paʻakikī.
ʻO 4,5,6,7 a me 8 ka mea i koho ʻia ʻo TUNGSTEN CARBIDE INSERT BITS no nā ʻano like ʻole o ka paʻakikī me 4 ka palupalu a ʻo 8 ka paʻakikī.
ʻO ka wehewehe code IADC no ka helu ʻelua:
ʻO ka 1,2,3 a me 4 ka haʻihaʻi hou ʻana o ka hoʻokumu ʻana me 1 ka palupalu a ʻo 4 ka paʻakikī.
ʻO ka wehewehe code IADC no ka helu ʻekolu:
1 a me 3: ka mea hāmama maʻamau (non-sealed roller bearing) roller bit
2: Haʻa hāmama maʻamau no ka ea wili wale
4 a me 5: wili ʻia i hoʻopaʻa ʻia i ka bit bearing
6 a me 7: puke pai i hoʻopaʻa ʻia i ka bit bearing
Nānā:
* ʻOkoʻa ma waena o 1 a me 3:
3 me ka carbide hoʻokomo ma ka kuʻekuʻe wāwae o ka cone, oiai 1 me ka ole
* ʻOkoʻa ma waena o 4 a me 5:
5 me ka carbide hoʻokomo ma ka kuʻekuʻe wāwae o ka cone, aʻo 4 me ka ʻole.
* ʻOkoʻa ma waena o 6 a me 7:
7 me ka carbide hoʻokomo ma ka kuʻekuʻe wāwae o ka cone, aʻo 6 me ka ʻole.
ʻO ka wehewehe ʻana i ka code IADC no ka helu ʻAha:
Hoʻohana ʻia nā code leka ma ke kūlana helu ʻehā e hōʻike i nā hiʻohiʻona hou.

Nā ʻano huila:
Aia ma mua o ʻehā (4) ʻano o ka hoʻolālā bearing i hoʻohana ʻia i nā bit wili trcione:
1) Maʻamau Haʻa Hāmama Roller Bit:
Ma luna o kēia mau ʻāpana e milo manuahi nā cones. Aia kēia ʻano ʻano bit i ka lālani mua o nā bearings a me ka lālani hope o nā bearings.
2）: Maʻamau Wehe Hala Roller Bit no ka ea wili
Ua like nā cones me #1, akā e hoʻokomo pololei ʻia ka ea i nā cones e hoʻomaha ai nā bearings.Kahe ka ea i loko o ka cone ma nā ala ala i loko o ka pine.
3) Hoʻopaʻa ʻia i nā ʻāpana huila
He sila O-Ring kēia mau ʻāpana me kahi waihona momona no ka lawe ʻana i ka ʻoluʻolu.
Hana nā sila ma ke ʻano he pale i ka lepo a me nā ʻokiʻoki e hana i nā bearings.
4) Nā Bits Roller Bearing Journal
ʻO kēia mau bits he ʻaila a hoʻomaʻamaʻa ʻia me nā bearings ihu, sila O-ring a me ka heihei no ka hana kiʻekiʻe.
Loaʻa i ka Far Eastern Tricone Bits ka pahu sila i hoʻopaʻa ʻia a me ke kaula sila metala.
