He mea hanga ā mātou poro pātene whakarara ki te kāpira kounga teitei, ā, he mea hanga mā te hangarau pēhi matao, ka taea te hono atu ki te paipa wiri whakarara mō ngā wiri waewae-hau, ki ngā wiri toka ringaringa rānei mō te keri i ngā maina koura me te waro, ngā keri māpere me te karāneti, ngā mahi kōhatu, ngā kauhanga, ngā whare tiaki wai, me ētahi atu.
He mea hanga tino pai ki te tungsten carbide me te rino remu, he kaha ārahi me te urunga mō te whakapiki i te hua, te tika pai, me te kounga o te horoinga o te poka kia whiwhi ai i te mahi keri mōrahi mō te tere penapena utu wahie.
Ka taea e mātou te hoahoa me te hanga i te whānui, te maha o ngā pātene me ngā kōhao whakawhiti, te āhua o te pātene, me te piko e ai ki te tauira, ki te tuhi rānei a te kiritaki. He mea hanga ā mātou mata pātene ki te tungsten carbide me te maitai kounga teitei, ā, ka tukatukahia ki te matao kia wātea ai mō te keri i te toka mārō me te iti rawa o te ngaronga pūngao mā te whakawhiti i te pūngao pānga kaha ki roto i te toka. Ki te whakatauritea ki ngā mata whao whakarara me ngā mata whakawhiti whakarara, he hangarau teitei ake ngā mata pātene, he roa ake te wā keri i te kotahi haerenga, ā, he pai ake te mahi keri. I runga i te here, ka taea te wehewehe i ngā mata pātene whakarara ki ngā momo porowhita me ngā momo porowhita.
Ko ngā mata pātene whakarara ngā mata whakarara rongonui, he whānuitia ngā diameter o te pane e wātea ana mai i te 26mm ki te 48mm. Mā te pēhi wera i ngā pātene carbide ki te taha o te mata, ka tukuna e ngā mata pātene whakarara he mahi keri pai me te roa o te mahi.
