Niho ōrite: te whānui o te porowhita piko me te whānui o te roera, ngā niho tauhou, te whānui o te porowhita piko D*COS(90/Z)+Dr diameter roera. Ko te whānui o te roera ko te whānui o ngā roera i runga i te mekameka. Ko te whānui o te pou ine he āwhina ine e whakamahia ana hei ine i te hohonutanga o te pūtake niho o te porokete. He porotaka, ā, he rite te rahi ki te whānui o te roera. Ko te tawhiti ine o te pou ine e whakamahia ana hei ine i te hohonutanga o te pūtake niho. he raraunga ine.
Ngā mōhiohio whānui:

E ai ki te āhua o te kōhao pereti mekameka me te āhua o te kakau pine, ka taea te wehewehe ki te mekameka niho Hy-Vo me te kōhao tohutoro porowhita me te kore-porowhita (āhua-āporo). Kōhao tohutoro hope roa mekameka niho Hy-Vo.
Mō ngā porotiti mekameka niho. E ai ki ngā āhua niho rerekē, ka taea te wehewehe ki te porotiti niho involute, te porotiti niho rārangi tika, te porotiti niho pewa, me ētahi atu; e ai ki ngā momo tuku rerekē, ka taea te wehewehe ki te porotiti rarangi kotahi, te porotiti rarangi rua, me te porotiti rarangi maha. Ngā porotiti, me ētahi atu; e ai ki ngā āhua rerekē o ngā pewa pito niho, ka taea te wehewehe ki ngā porotiti kore-runga-tapahia me ngā porotiti tapahi-runga;
E ai ki te hanganga o te pereti arataki mekameka niho, ka taea te wehewehe ki te poro arataki o waho me te poro arataki o roto; e ai ki te tikanga tukatuka poro, ka taea te wehewehe ki te poro hobbing, te poro mira, te poro shaper, te poro metallurgy paura, me ētahi atu.
