Ma waho aʻe o ka hoʻonui ʻana i ka lubricity, hana pū ka mālama ʻana i ka ʻeleʻele oxide i nā ʻeke liʻiliʻi ma ka ʻili o ka mea hana e hiki ai ke hoʻopaʻa i ka coolant kokoke i ka ʻoki ʻoki no nā manawa lōʻihi. Ma muli o ka hoʻomaʻamaʻa ʻana i ka ʻili o ka oxide ʻeleʻele ma ke kila kiʻekiʻe, ua hoʻonui ʻia ka mea hana i ka pale ʻana i ka wela a hoʻonui ʻia i kona ola mea hana, me kahi ʻāpana oxide thinr ma mua o ka mea maʻamau e ʻike ai i nā mea hao cobalt; ua like kona hana me na mea paahana i uhi ole ia. Hiki ke hoʻohana i nā shanks poepoe me nā ʻano mea hana like ʻole.

ʻO nā wili me kahi māhele o 118 a i ʻole 135 degere ʻo ia hoʻi ka liʻiliʻi o ka ikaika e koi ʻia e wili i loko o ka mea hana, e pale ai i ka paheʻe ʻana o ka drill ma luna o ka ʻili o ka mea, e hoʻokau pono iā ia iho a e hoʻemi i ke koi e koi ʻia e wili. He hoʻolālā ʻokoʻa ko kēia drill me kahi ʻaoʻao ponoʻī e pale i ka paheʻe, e wikiwiki a maʻalahi ka hana. ʻO ka hoʻonui ʻana i ka wikiwiki o ka drill ʻo ia ka liʻiliʻi o ka wela a loaʻa ka lole hou aʻe, e hoʻolōʻihi i ke ola o ka drill. ʻOi aku ka ʻoki ʻoki a kū i ka hoʻohana mau ʻana. I ka hana ʻana ma kahi ʻaoʻao kūʻē i ka ʻoki (ʻoki lima ʻākau), kipaku nā mea ʻoki helical-fluted i nā ʻāpana i luna ma o ka ʻoki e hōʻemi i ka pipili.
