ʻO nā pahu hoʻoheheʻe Cobalt, ka hopena no nā noi wela kiʻekiʻe a me ka ʻeli ʻana i nā metala paʻakikī. Hoʻohui ia i kahi kiʻekiʻe o ka cobalt i ke kila kiʻekiʻe, ua hoʻolālā ʻia i nā wela kiʻekiʻe a hana maikaʻi i ka wā e wili ai i ke kila kila a me nā mea paʻakikī ʻē aʻe.
He kū hoʻokahi kā mākou pahu pahu cobalt no ka lōʻihi a me ka hana. 'A'ole like me nā hss drill bits ma'amau, pa'a nā pahu drill cobalt a hiki ke pale i nā hana wili koi. ʻOi aku ka wikiwiki a ʻoi aku ka maikaʻi o nā lua, e hoʻolilo iā lākou i koho kūpono no ka poʻe loea a me nā mea hoihoi DIY.
ʻO kekahi o nā hiʻohiʻona koʻikoʻi o kā mākou cobalt drill bits ko lākou pale ʻana i ka wela, e ʻae iā lākou e hana no nā manawa lōʻihi me ka ʻole o ka wela a me ka nalowale ʻana. ʻO kēia ka mea kūpono iā lākou no nā noi e koi ana i ka wili hoʻomau, e hōʻoia i ka hana ʻole a me ka maikaʻi.
Hāʻawi kā mākou hale hana i ʻelua mau pahu pahu pahu cobalt e hoʻokō i nā pono wili like ʻole. Aia ka 5% cobalt i loko o nā pahu hao kila M35 a ua kaha ʻia ʻo "hss co" ma ka shank bit drill. Hāʻawi kēia mau drill bit i ka ikaika a me ka paʻakikī no nā ʻano hana wili.
No ka hana ʻoi aku ka maikaʻi, hāʻawi pū mākou i nā ʻāpana drill kila M42 kiʻekiʻe, aia ka 8% cobalt. Hōʻailona ʻia ʻo "HSS CO8" ma ka shank, ua hoʻolālā kūikawā ʻia kēia mau drill bits e hāʻawi i ka hana wili lua ʻole a me ka lōʻihi. Hoʻolālā ʻia lākou e lawelawe i nā hana wili paʻakikī me ka maʻalahi, e hana iā lākou i koho hope loa no nā poʻe loea e koi ana i ka hana maikaʻi loa.
E hoʻokomo i kā mākou pahu pahu cobalt a ʻike i ka ʻokoʻa o ka hana a me ka lōʻihi. E ʻōlelo maikaʻi i ka wili lohi ʻole a maikaʻi ʻole a hoʻokipa i kahi au hou o ka wikiwiki, ʻoi aku ka pololei a me ka lōʻihi o ka hoʻonā ʻana i ka wili. Me kā mākou mau pahu drill cobalt, hiki iā ʻoe ke hoʻoponopono i nā pilikia drilling me ka hilinaʻi a loaʻa nā hopena koʻikoʻi i kēlā me kēia manawa.
