Nō reira, he mea tino nui te whiriwhiri i te mata keri tika i roto i ngā kaupapa keri toka.
Mō ngā mata wiri pēhanga teitei (mata wiri), e whā ngā momo hoahoa mata pito matua e whakamahia ana i tēnei wā, arā: te momo mata pito pūkohu, te momo mata pito papatahi, te momo mata pito kōpiko me te momo mata pito hohonu kōpiko pokapū. Ko te nuinga o te wā, ka whakamahia e te carbide ngā niho pōro, ngā niho puna, ngā niho pōro me ngā niho puna mō te whakaritenga niho.
1. Momo mata pito pūkohu: Ka taea e te mata keri raro-poka te pupuri i te tere keri toka teitei i te wa e keri ana i nga toka whakakoi waenga-pakeke me te pakeke, engari he ngoikore te tika o te keri, a, kaore i te pai mo nga kaupapa keri toka me nga whakaritenga teitei mo te tika o te poka pupuhi.
2. Momo mata pito papatahi: He kaha, he pakari te mata keri pēhanga teitei o te mata pito papatahi (mata keri) ki raro i te kōhao, ā, he pai mō te keri i ngā kōhatu mārō me ngā kōhatu tino mārō. He pai hoki mō te keri i ngā kōhatu waenga-mārō me ngā kōhatu ngohengohe, he iti noa ngā whakaritenga mō te tika o te kōhao pupuhi.
3. Momo mata pito kōpiko: Ko te mata pito kōpiko he mata pito pēhanga teitei ki raro i te poka (mata poka) he wāhanga kōpiko kōniko kei te mata pito, ka hanga he pānga pūngao iti i te wā o te tukanga keri toka, ka mau tonu te mahi pokapū o te mata poka, ā, he pai te tika o te poka pupuhi kua keria. Hei tāpiri, he pai ake te pānga tango puehu o tēnei mata poka, ā, he tere ake te tere keri. He mata poka pēhanga teitei ki raro i te poka e whakamahia nuitia ana i tēnei wā i te mākete.
4. Momo pokapū piko hohonu o te pito mata: Ko te mata keri hohonu o te pito mata, he momo pokapū piko teitei, he pēhanga hau nui kei waenganui o te mata o te pito (mata keri), e whakamahia ana mō te whakapūtanga i roto i te tukanga keri toka. Mā te keri poka hohonu ka taea te pupuri i te tika o te poka pupuhi, engari he ngoikore ake tōna kaha o te pito mata i ētahi atu momo mata keri, nō reira he pai anake mō te keri toka ngohengohe me te toka waenga-mārō.
