He porotaka te mata o waho o ngā nati raka tika KMTA, ā, he mea hanga mō ngā mahi e hiahiatia ana te tino tika, te huihuinga ngāwari me te raka pono.
E toru ngā pine maukati o ngā nati raka tika raupapa KMT me KMTA e ōrite ana te tawhiti huri noa i ō rātou porowhita, ka taea te whakakī mā te whakamahi i ngā tīwiri kua whakaritea hei mau i te nati ki te kakau. Ka mīhinihia te mata pito o ia pine kia rite ki te miro o te kakau. Ina whakakīia ngā tīwiri raka ki te taipana kua tūtohutia, ka nui te waku i waenga i ngā pito o ngā pine me ngā taha miro kua tangohia kia kore ai e wetekina te nati i raro i ngā tikanga mahi noa.
Kei te wātea ngā nati raka KMTA mō te miro M 25×1.5 ki te M 200×3 (rahi 5 ki te 40)
