Ko ngā taputapu pūtorino tika ine he taputapu whānui mō te tapahi miro i roto i ngā kōhao kua keria i mua. Ka taea te whakamahi hei tapahi miro i roto i ngā kōhao mā roto, i ngā kōhao matapo rānei. Ka tīmatahia he miro mā te whakamahi i tētahi taputapu whakawhāiti me te whakawhiti diameter ngawari mō te iti o te hiahia taipana. Kātahi ka whakamahia he taputapu waenga hei whakaoti i te miro, kātahi ka whakamahia he taputapu raro hei whakaoti i ngā miro, inā koa i roto i ngā kōhao matapo. Kei te wātea ngā taputapu pūtorino tika i roto i ngā rahi paerewa ine me ngā āhua miro.

Painga:
Ko te roa rawa o te ora o ngā taputapu he mea hanga ki te maitai tungsten kounga teitei.
Ka whakapai ake i te pakari me te pana maramara mā te arotau i te āhua o te taha me te putorino mā te whakamahi i ngā miro tīwiri tapahi pumau.
He mahi teitei, kāore e hiahiatia he rauemi mahi, he mīhini, he āhua tapahi, he ngāwari hoki.
Ngā maramara pumau me ngā wāhanga tapahi mai i ngā maitai hanganga ki ngā maitai kowiri tira, ngā koranu konumohe.

Āhuatanga:
1. He tapahi koi, he ātete ki te kakahu, he pakari hoki
2. Kāore e piri ki te maripi, kāore e ngāwari te whati i te maripi, he pai te tango i ngā maramara, kāore e hiahiatia kia orohia, he koi, ā, he ātete ki te kakahu
3. Te whakamahi i tētahi momo mata tapahi hou me te mahi tino pai, he mata maeneene, kāore e ngāwari ki te pakaru, ka whakanui ake i te pakari o te taputapu, ka whakapakari i te pakari me te tango i te maramara takirua.
4. Hoahoa anga, ngāwari ki te piri.

Ngā raruraru noa o te tukatuka miro

Kua pakaru te puna:
1. He iti rawa te whānui o te kōhao o raro, ā, kāore i te pai te tango i te maramara, ka ārai i te tapahi;
2. He tino teitei rawa te tere tapahi, he tere rawa hoki i te wā e pato ana;
3. He rerekē te tuaka o te taputapu e whakamahia ana mō te pato i te diameter o te kōhao raro kua mirohia;
4. Te kōwhiringa hē o ngā tawhā whakakoi tap me te pakeke kore pumau o te mahi;
5. Kua roa te whakamahinga o te pūwero, ā, kua tawhito rawa.
Ngā taputapu i hinga: 1. He nui rawa te koki o te taputapu i tīpakohia;
2. He nui rawa te matotoru o te tapahi o ia niho o te taputapu;
3. He nui rawa te pakeke o te tap;
4. Kua roa te whakamahinga o te pūwero, ā, kua tino tawhito.

Te whānui o te piko o te taputapu: te kōwhiringa hē o te whānui o te piko o te taputapu; te kōwhiringa tapahi kāore i te tika; te tere tapahi teitei rawa o te taputapu; te hononga ngoikore o te kōhao o raro o te miro o te taputapu me te mea mahi; te kōwhiringa hē o ngā tawhā whakakoi taputapu; te tapahi taputapu He poto rawa te roa o te kōne. He iti rawa te whānui o te piko o te taputapu: kua hē te kōwhiringa o te whānui o te piko o te taputapu; kāore i te tika te kōwhiringa tawhā o te taha taputapu, ā, kua tawhito te taputapu; kāore i te tika te kōwhiringa o te wai tapahi.
