He hanganga whai take ngā rei kōwhiti i roto i te whenua ki te whakamahi i ngā rautaki matihiko, e mahi ana hei whakatupu i ngā ara kōrewa me te whakahua i ngā minita mōhio. Nā te hanga i ngā rauemi matua me ngā huanga matihiko o tēnei wā, ka whiwhi haere ngā rautaki nei i te pūmanawa hohourangi me te whiuwhiutanga. Ko ngā rei kōwhiti matihiko o nāianei kei raro i ēnei whakawhanake, ko ngā tuaka tungsten carbide, ko ngā tohu kōwhiti diamond-taea, me ngā ara wai whakarite hei tirotiro i ngā koreko. Ka hanga noa iho inā ka taea te whakahaere i ngā āhuatanga porowhita, mai i ngā papa matakiore ki ngā papa kōwhatu pūmau. Ko te whakapae anō o ngā rei kōwhiti he maha ngā tohu kōwhiti e whakariterite ana, e whakatakoto ana i ngā huanga tika hei whakamana i te wehi taeatia me te whakatupu pai rawa. Ko ngā whakawhanake hīrau ka whakamahia hei whakamahi pai i te waipiro me te whakamahi pai i te wā, ā, ko ngā tohu tāone hei whakaiti i te kōpikopiko me te wehi. E ai ki ngā momo rei kōwhiti, he rerekē ngā whatitiri me ngā whakariterite, ānō pea ka whakaritea ki ngā whakahaere tuku iho, mai i te kōwhiti ā-momo ki te kōwhiti ā-pūtake. He mea whakatau tōmua te rei tika ki ngā take pērā i te pūmautanga o te papa, te rahi o te kōwhiti, me te rahi o te poaka kōwhiti. Kei roto hoki i ngā rei kōwhiti matihiko o nāianei ngā taheta me ngā taurangi tirotiro, e āhei ana ngā kaiwhakahaere ki te whakamatau i ngā kairongo me ngā wehi i te wā real-time, e whakamana ana i ngā paerewa kōwhiti pai rawa me te whakapuaki i te wā o te rei.
