Ka tupu pai ngā taiao mīhini i runga i te maha o ngā whakamahinga. Ko te kaha ki te whakahaere i te whānuitanga o ngā rauemi, te rahi o ngā miro, me ngā whakaritenga tono me te kore e whakarerekē tonu i ngā taputapu he mea tino whai hua.Ngā whakaurunga tapahi carbidei hangaia me te momo tihi wāhanga 60° ā-rohe, kei te puta ake hei taputapu kaha mō te whakatutuki i tēnei whānuitanga e hiahiatia ana, te whakangāwari i ngā tatūnga me te whakawhānui i ngā āheinga.
Ko te koki miro 60° te paerewa ā-ao mō te nuinga o ngā miro mīhini (hei tauira, Metric, Unified National, Whitworth). He maha ngā whakamahinga o tētahi whakaurunga kua arotauhia mō tēnei āhua whānui. Ka whakanuia ake tēnei whakamahinga e te āhua kōtaha ā-rohe. Mā te arotau i te āhua tapahi mō ngā āhuatanga o te hanga i tēnei kōtaha 60°, ka tino pai te mahi a te whakaurunga puta noa i te whānuitanga o ngā āhuatanga. He tino pai ki te whakaputa i ngā miro o roto, o waho hoki me te ōrite o te matatau.
He mea nui ake, mā te mana whakahaere maramara atamai me te mata tapahi pakari e whakaratohia ana e te kōtaha ā-rohe ka taea e ēnei whakaurunga te aro atu ki te whānuitanga o ngā rauemi. Mai i ngā āhua kapia o te konumohe me ngā maitai waro-iti ki te kakahu whakakoi o te rino maka me te kaha teitei me te āhua whakapakeke mahi o ngā maitai kore waikura me ngā koranu nikara, ko tengā whakaurunga tungsten carbideKa urutau te āhuahanga. Ka whakahaere pai i te hanganga maramara i roto i ngā rauemi ngohengohe hei ārai i te aukati me te taha hanga, me te whakarato i te kaha o te taha me te ātete kakahu e tika ana mō ngā mahi uaua ake, he koi ake. Ka whakaitihia te hiahia mō ngā whakaurunga motuhake mō ia rerekētanga iti o te rauemi, te rahi miro rānei i roto i te whānau 60°. Ka whiwhi ngā mīhini me ngā kaihōtaka i te ngāwari, ka māmā ake ngā whakaritenga rarangi taonga, ā, ka whakaitihia ngā wā tatūnga. Ahakoa he tauira e hiahia ana ki ngā miro i roto i te koranu tauhou, he whakahaere whakaputa rānei e uru ana ki ngā rauemi maha, ka tukuna e ēnei whakaurunga he otinga pono, he mahi teitei, ka waiho hei rawa nui mō tetahi pokapū mīhini hou.
