API pōhaku drill bit IADC537 5 1/2 ” (139.7 mm) no ka luawai paakiki
Hōʻike huahana
ʻO ke kūʻai nui ʻana o ka API TCI i hoʻopaʻa ʻia i nā ʻāpana huila i loko o ke kumukūʻai mai ka hale hana ʻo Kina no ka mīkini wili.
ʻO ke ala hoʻāʻo maikaʻi loa no nā ʻāpana wili:
1. E hoʻopaʻa i ka ROP (e like me ka mea i hōʻike ʻia ma ka papa ma lalo nei).
2. E hoʻonui haʻahaʻa i ka WOB a mālama i ka RPM like a me ka hoʻoheheʻe ʻana ma lalo o kēia WOB no 5 mau minuke a hoʻopaʻa hou i ka ROP (e like me ka hōʻike ʻana ma ka papa ma lalo).
3. E ho'ēmi i ka WOB b i ka laulā like a e hoʻomau i ka ʻanuʻu 2.
4. E huli i ka WOB ma nā pū'ulu ho'ā'o ma mua o ka hiki ke hā'awi mai i ka ROP ki'eki'e loa.
5. E hoʻololi pono i ka RPM ma lalo o ka WOB maikaʻi loa a hoʻopaʻa i ka ROP (e like me ka hōʻike ʻana ma ka papa ma lalo).
6. E koho i ka RPM ma ka ROP kiekie loa.
7. E hoʻonoho i ka palena wili i ka hui maikaʻi loa

ʻO Far Eastern kahi hale hana kūikawā i nā bit drill, e like me nā tricone bits, PDC bits, HDD hole opener, Foundation roller cutters no nā noi like ʻole.
Ma ke ʻano he hale hana drill bits ma Kina, e hoʻonui i ke ola hana drill bit kā mākou pahuhopu. Ke ho'āʻo mau nei mākou e hoʻomaikaʻi i nā'āpana me nā helu komo kiʻekiʻe.ʻO kā mākou kumu e kūʻai aku i ke kūlana kiʻekiʻe me ke kumu kūʻai haʻahaʻa.
