NGA MOKA NIHO mira WAJA
IADC 1 SERIES DRILL BITS
Ka whakamahia enei paraire ki te keri i te kaha iti-kopeke, nga hanganga ngawari.Ka whakamahia te roa o nga niho matapae i runga i nga porowhita teitei hei whakarato i nga reiti urunga nui rawa atu.Ka whakamahia te anga-a-waa hei whakahaere i nga kakahu niho.I runga i nga momo moka ngawari ka kapi katoa nga niho moka e tenei anga maro.
IADC 2 SERIES DRILL BITS
Ka whakamahia enei moka ki te keri i nga hanganga pakeke me te hangai.Ko nga niho poto rawa, tata te mokowhiti me te iti rawa o te ahua pakeke ka whakamahia mo te aukati pakaru.Ko enei paraire me tu ki nga taumahatanga teitei me te ruri i nga hanga abrasive me te mahi kuru, tapahi.

Nga korero mo te whakamahi i nga moka roera koeko:
1. I mua i te hekenga o te moka, me whakapumau he ma o raro o te puna, kaore he kirikiri, kaore he whakarewa e taka.
2. Tirohia mehemea kei te mau tonu te hurihanga hononga miro o te moka roera koekoe, ka tika te whakauru o te puha.
3. Ko te rere i roto i te poka me noho pumau, karo i te ahotea me te aukati i te keri.
4. Ko te hononga whakamutunga e hiahia ana kia nui te neke ki te timata i te teepu hurihuri me te reaming tonu ki raro o te puna., kia tino horoia te puna kia kore ai e pakaru te para i te puha.
5. Ko te ahua o te kohao o raro kia ngawari te pehi me te ata huri ki te whakapiri ki raro o te puna, te pehanga iti, te iti o te tere, te nekehanga nui, te taipana iti, me te tere ko te 40~60 rev / min, i te iti rawa 30 meneti.
6. Whakatauhia te taumaha o te moka me te tere ki te whakakotahi me nga tikanga o te hanganga.
7. I te wa e keri ana i mua, kia maeneene te mahi, kia rite te kai wiri, karekautia te hiki me te tuku i te wiri kia kaha, karekau i pai te tarai me te wiri aho ka hinga kore.
8. Mena ka kitea ka mutu te ahunga whakamua o te moka, ka piki te pehanga papu me te heke, ka heke ohorere te tere o te kuhu, ka piki ake te taipana, whakaarahia te drill ki te tirotiro me te kore whakaroa.
