* Hiki ke hana i nā ʻano metala like ʻole (me ke kila hoʻopau ʻole) a me nā mea metala ʻole e like me ke kinikini, jade a me ka iwi.Me ka paakiki a hiki i ka HRC70,.
* No ka hoʻololi ʻana i ka huila wili liʻiliʻi i ka nui o nā manawa, ʻaʻohe lepo lepo i hana ʻia.,
* ʻO ka maikaʻi machining maikaʻi a me ka maʻalahi kiʻekiʻe e kūpono i ka mīkini ʻana i nā ʻāpana ʻokoʻa me ka pololei kiʻekiʻe;
* Ke ola lawelawe lōʻihi, 10 mau manawa i nā mea hana kila kiʻekiʻe a me 200 mau manawa i ka huila wili liʻiliʻi i ka lōʻihi.
* Maʻalahi e mālama a hana.Palekana a hilinaʻi, hiki ke hōʻemi i ka ikaika o ka hana a hoʻomaikaʻi i ke kūlana hana;
*ka pōmaikaʻi hoʻokele waiwai kiʻekiʻe, hiki ke hoʻemi ʻia he 10% o ke kumukūʻai kaʻina hana.
ʻO ka maʻamau, ʻo 6000-50000 ka wikiwiki o nā mea uila a i ʻole pneumatic.
No ka hoʻohana palekana, pono e hoʻopaʻa pono ʻia nā burrs rotary carbide i ka wā o ka hana, e pale aku i ka hānai ʻana, ʻoi aku ka maikaʻi o ka wili hoʻohuli.No ka pale ʻana i kou mau maka me nā aniani pale a pale i ka pīpī mai ka paʻi ʻana i ka manawa like.
