He kowiri tira kowiri tira kowiri tira matūriki koki. Ka taea te whakamahi hei whakakapi i nga momo kohuke me te kore-metallic abrasives, penei i te alumina, te carbide silicon, te kirikiri kiripaka, te pirepire karaihe, me etahi atu.
Ko te kowiri tira ka whakamahia te nuinga mo te horoi i te mata, te tango peita me te whakaheke i nga konganuku kore-ferrous me nga hua kowiri tira, te hanga i te taratara o te mata, na reira e tika ana mo te maimoatanga o mua o te mata i mua i te paninga. Ka whakatauritea ki nga abrasives kore-whakarewa, kowiri tira ka awhina ki te whakaheke i nga utu whakahaere me te tuku puehu me te whakapai ake i te taiao mahi.
Ko te kirikiri rino kowiri he roa te ora o te mahi me te tino pai o te pupuhi, te whakamaarama i te mahi pupuhi, te penapena utu, te whakatutuki i te kounga o te pupuhi, te taratara me te ahua.
