1. Ātete Tino Pai mō ngā Hanganga Mārō He mea hanga ki te mata tungsten carbide kiato-teitei, ka tu atu te mata i te pakū nui i roto i te toka mārō (hei tauira, te karāneti, te quartzite) me ngā taiao pēhanga-teitei/pāmahana-teitei (HPHT). Ka whakaitihia te kakahu o te mata mā te 30%+ ki te whakataurite ki ngā mata mata paerewa, kia roa ake ai te ora o te mahi i roto i ngā āhuatanga keri uaua.
2. Te Pai o te Whai Hua o te Keri me te Tere o te Whakauru Ko te hanganga tapahi kua whakapaitia me te tahora tapahi PDC kua whakarei ake me te koki rake whakamuri ka whakanui ake i te pa ki ngā hanganga toka mārō. Ka tukuna he ROP (Tere o te Whakauru) teitei ake i ngā mata porotaka kone tuku iho, ka whakapoto i ngā huringa keri me te whakaiti i ngā utu keri mō ia putu.
3. Ātete Kaha ki te Pānga me te Taipana Ka whakapai ake te hoahoa tinana matihiko whakapakari i te pumau o te hanganga, ka taea ai e te mata te tu atu i te wiri nui me ngā rerekētanga taipana i roto i te toka mārō pakaru. Ka whakaiti i te kino o te mata me te hinga wawe, ka whakaiti i te auau takahuri me te wā kore hua (NPT).
4. Te Kounga Tika o te Pūwero me te Pūmautanga o te Pūwero Mā te hoahoa waipēhi matatau ka taea te tango i ngā tapahi kia pai ai te tango, kia kore ai e pōro me te piri ki ngā hanganga mārō. Ka mau tonu te whānui me te poutū o te pūwero, ka whakaiti i ngā uauatanga o te rere o te anga me te whakapai ake i te pai o te whakaoti i te pūwero.
