Mo te aukume kohua countersunk, ka miihinihia te kohao countersunk o te aukume kohua mai i te mata o teNeodymium kōpae aukumeki roto o te aukume,Neodymium countersunk aukume. He mea noa i roto i te waahi o te hanga miihini me te hanga ki te whakauru i nga tutaki me etahi atu waahanga hono. Ka taea e te kohao countersunk te karo i te toronga o te tira me te whakarite i te papatahi o te waka rererangi whakaurunga. Ko te tikanga tukatuka o te poka countersunk ko te keri me te tukatuka counterbore. Ka wehea te porowhita ki te papatahi o raro papatahi me te koeko counterbore. Ahakoa he aha te ahua o te counterbore, he mea tika ki te wiri i te matua i roto i te rua ki te moka drill, ka kowhiri i nga taputapu rereke mo te tukatuka counterbore i runga i te ahua o te countersink. He mea tika ki te mira te porowhita ma te kaitapahi mira mutunga i runga i te keri. He mea tika ki te countersink i runga i te poka keri me te moka keri nui ake. I roto i te tukanga o te machining counterbore, me tuu te wahi mahi kotahi ki te whakarite i te coaxiality o te poka me te counterbore.
Na tenei hanganga ngawari, he tino ngawari ki te kuti i te wiri porotiti ki roto i te kohao aukume kohua. Ka kitea nuitia i roto i nga umanga, whare putunga, me te whakamahi i ia ra.
