Mīti DTH Pēhanga Hau Teitei 5-6 inihi

Ngā tono:

E whakamahia whānuitia ana ngā mata keri DTH i roto i te keri whenua, i ngā rua keri, i te hangarau waipēhi me te hiko-wai, i te keri puna wai, i te tūhuratanga kohuke, i te keri poka punga, i te hangarau waiariki, i te keri raro whenua, me ētahi atu hangarau ā-iwi. He painga tōna: he papatahi te pakitara o te poka, he māeneene te pakitara o te poka, he pakari te tokotoko me te hama o te keri, kāore e pāngia e te pana axial teitei, kāore he rohe o te hohonu o te keri, he iti te utu o ngā taputapu, ā, he ngāwari ki te tiaki.

Painga o te Pēhanga Hau Teitei o te DTH Bit:

Te roa o te ora o te drillte rauemi koranu, he roa ake te ora whakamahi, he pai ake i ngā hua ōrite;

Teitei o te Whai Hua o te Keri: he ātete te whakamahi i ngā pātene wiri, kia koi tonu ai te wiri, ā, ka tere ake te keri.

He pumau te tere o te keri: ka waruhia te mata, ka tapahia hei wahi i te toka.

Mahi PaiHe kaha te ātete o te mata taimana hou ki te kakahu, he pai te tiaki i te diameter, ā, ka taea te whakamahi pai i ngā niho tapahi.

Te whakamahi i te whānuitanga o ngāMā te mahi nei ka kitea he pai te keri mō te toka warowaihā, te kōhatu iti, te toka uku, te toka paru, te toka kirikiri me ētahi atu momo ngawari me ngā momo mārō (9-taumata te kaha ki te keri i te toka, te keri i te toka mārō), ki te whakataurite ki te keri noa, inā koa te keri i te toka 6-8 taumata te nui o te pānga.
