He wāhanga nui te keri hinu me te hau i roto i te umanga pūngao, ā, me whai hangarau matatau hei tango rauemi mai i te whenua. Ko ngā taputapu tapahi PDC, ko ngā taputapu tapahi taimana polycrystalline rānei, he hangarau hou kua huri i te tukanga keri. Kua hurihia e ēnei taputapu tapahi te umanga mā te whakapai ake i te whai huatanga o te keri, te whakaiti i ngā utu, me te whakanui ake i te haumaru.
He mea hanga ngā taputapu tapahi PDC mai i ngā taimana hangai ka whakakoihia ngātahitia i raro i te pēhanga teitei me te pāmahana teitei. Mā tēnei tukanga ka hangaia he rauemi pakari, pakari hoki, ā, he ātete ki te pakaru me te haehae. Ka whakamahia ngā taputapu tapahi PDC i roto i ngā mata wiri, arā, ngā taputapu e whakamahia ana hei keri ki roto i te whenua. Ka piri ēnei taputapu tapahi ki te mata wiri, ā, ko rātou te kawenga mō te tapahi i ngā hanganga toka kei raro i te mata.
Ko tētahi o ngā painga matua o ngā taputapu tapahi PDC ko tōna pakari. Ka taea e rātou te tu atu ki ngā pāmahana me ngā pēhanga teitei, ā, he mea pai mō te whakamahi i roto i ngā mahi keri. Kāore i rite ki ngā mata keri tuku iho, he mea hanga ki te maitai, kāore ngā taputapu tapahi PDC e tere te pakaru. Ko te tikanga ka roa ake te ora, ka whakaiti i te hiahia mō te whakakapinga pinepine, ā, ka whakaiti i te utu whānui o te keri.
Ko tētahi atu painga o ngā taputapu tapahi PDC ko tōna whai huatanga. Nā te mea he tino pakari, ka taea e rātou te tapahi i ngā hanganga toka kia tere ake i ngā mata keri tuku iho. Ko te tikanga o tēnei ka taea te whakaoti tere i ngā mahi keri, ka whakaiti i te wā me te utu e pā ana ki te keri. Hei tāpiri, he iti ake te tūponotanga o ngā taputapu tapahi PDC kia mau, kia pakaru rānei i roto i te kōhao, ka whakaiti i te mōrearea o te wā kore mahi me te ngaronga o te hua.
Kua whakapai ake hoki ngā taputapu tapahi PDC i te haumaru i roto i te umanga hinu me te hau. Nā te tino whai hua, ka tere ake te whakaoti i ngā mahi keri, ka whakaiti i te wā e pau ana i ngā kaimahi ki ngā taiao morearea. Hei tāpiri, nā te mea he iti ake te tūponotanga o ngā taputapu tapahi PDC kia mau, kia pakaru rānei i roto i te poka, he iti ake te tūponotanga o ngā aituā me ngā whara.
Hei whakarāpopototanga, he hangarau hou ngā taputapu tapahi PDC kua huri i te umanga keri hinu me te hau. He maha ngā painga e tukuna ana e rātou, tae atu ki te roa, te whai hua, me te haumaru. I te haere tonu o te whanaketanga me te tipu o te umanga pūngao, he tūponotanga ka nui haere te mahi a ngā taputapu tapahi PDC ki te whakatutuki i ngā hiahia pūngao o te ao.
