He tino pai ngā mata kōhatu PDC mō te keri puna hinu me ngā taputapu tapahi taimana polycrystalline pakari, e whakarite ana i te ātete ki te kakahu me te roa o te ora mahi. Ka tere ake te uru ki roto i ngā hanganga ngohengohe ki te pakeke-waenga, ka whakaiti i te wā me ngā utu keri. Mā te ātete kaha ki te pānga me te mahi pumau, ka urutau ki te whenua uaua, ka whakaputa i ngā poka puna ma, ka whakaiti i te wā kore mahi. Ka whakanui ake ēnei mata i te pai o te keri, te pono, me ngā painga ōhanga mō ngā mahi hinu.
