Ko nga ahuatanga o te miro rino tiwai / urupa whao whao ao
1. He hanganga kiato, he ahua ataahua me te whakaheke i te hongere rere. Nga ahuatanga o te hanganga: BB, WB ranei;
2. Ko te mata hiri he mea hanga ki te koranu rino, ki te carbide cimented ranei. He tika te rite o nga rauemi hiri me te roa o te ora mahi;
3. Ko te kōpae takirere he koeko, a ka whakaratohia te kakau takirere ki te hiri hurihuri, he pai te mahi hiri. He nitrided te mata o te kakau takirere, he pai te waikura me te waku. Ko te tarapi ka tango i te kauwhata ngawari, me te hiri pono, te mahi ngawari me te iti o te whakatuwhera me te kati kati;
4. Ka taea te kowhiri i nga momo paerewa paipa me nga momo hononga (penei i te whiri turanga, i te reke me te hononga miro).
