Nā ʻāpana niho API Mill IADC217 12 1/4 iniha (311mm) no ka wili luawai
Hōʻike huahana
ʻO Tricone bit kahi mea hana hoʻoheheʻe koʻikoʻi no ka hoʻoheheʻe ʻana i ka ʻaila, ʻo kāna hana hana e hoʻopili pololei i ka maikaʻi o ka wili ʻana, ka maikaʻi o ka wili ʻana a me nā kumukūʻai wili. ʻO ka wili ʻaila a me ka wili honua ka mea i hoʻohana nui ʻia a i ʻole cone bit. Loaʻa i ka ʻāpana cone ka hopena o ka wili ʻana, ka ʻoki ʻana a me ka ʻako ʻana i ka pōhaku hoʻokumu i ka ʻōwili ʻana, no laila hiki ke hoʻololi ʻia ka bit cone i nā papa palupalu, waena a paʻakikī. ʻOi loa i ka jet cone bit a me ka lōʻihi nozzle ma hope o ka puka ʻana o ka cone bit, ʻo ka cone drill bit drilling speed i hoʻomaikaʻi nui ʻia, ʻo ia ka mōʻaukala o ka hoʻomohala ʻana o ka cone bit kahi kipi nui. Hiki ke hoʻokaʻawale ʻia ka bit cone i nā niho (niho) ma ke ʻano niho, niho (bit) (hoʻonohonoho ʻia nā niho me nā niho carbide) bit cone; e like me ka helu o na niho hiki ke maheleia i hookahi cone, papalua , Ekolu-cone a me multi-cone bit. Ma ka home a me ka ʻāina ʻē e hoʻohana i ka hapa nui loa, ʻo ka mea maʻamau ka Tricone bit.
: 1. E koho i nā huahana kūpono loa.
2. E like me nā ʻano pōhaku, ke koho ʻana i ke ʻano maka, ke ʻano niho pihi.
3. E like me ka manao like ole,. ke koho ʻana i ke ʻano kino like ʻole
