Ngā moka hiri i hangaia e te wheketere IADC127 6 inihi (152mm)

E ai ki te rauemi tapahi, ka taea te wehewehe i ngā moka kōne e toru ki te moka TCI me te moka Niho Mira.
Ko tētahi atu ingoa o ngā mata tricone niho rino ko te mata tricone niho mira nā te mea ka hangaia ngā niho e te mīhini mira, ko te mata kōne he mea mārō ki te tungsten carbide.
He mea hanga ngohengohe rawa te niho mira IADC127. He mea nui te whiriwhiri i ngā mata keri toka tika i mua i te tīmatanga o te kaupapa.
Ka taea e te pakeke o ngā toka te ngohengohe, te pakeke waenga, te pakeke tino pakeke rānei, ka rerekē pea te pakeke o tētahi momo toka, hei tauira, he toka kōhatu, he toka onepū, he toka kōhatu ngohengohe, he toka kōhatu waenga, he toka kōhatu pakeke hoki te kirikiri, he toka kōhatu waenga, he toka onepū pakeke hoki, me ētahi atu.
I roto i te kaupapa keri, he 15 tau a Far Eastern me te neke atu i te 30 whenua o te wheako ratonga ki te whakarato i ngā mata keri me ngā wairua keri matatau mō ngā tono maha. Kei roto i ngā tono ko te mara hinu, te hau māori, te tūhura whenua, te keri awa, te keri, te keri puna wai, te HDD, te hanga, me te turanga. Ka taea te whakarite i ngā momo mata keri kia rite ki ngā hanganga toka rerekē nā te mea kei a mātou ake wheketere tohu API me ISO mō ngā mata keri. Ka taea e mātou te whakarato i te otinga a tā mātou miihini ina taea e koe te whakarato i ngā āhuatanga motuhake, pēnei i te pakeke o ngā toka, ngā momo taputapu keri, te tere hurihuri, te taumaha o te mata me te taipana. Ka āwhina hoki mātou ki te kimi i ngā mata keri e tika ana i muri i tō whakamōhio mai ki a mātou mō te keri puna poutū, te keri whakapae rānei, te keri puna hinu, te keri Kore-Keri, te whakatō turanga rānei.
