Izina ryuzuye ryinyo ya basin inguni ni: itandukanyirizo rikora kandi ryoroshye, rigabanijwemo ibice bibiri: amenyo yinyo n amenyo yingenzi. Kugabanya icyiciro kimwe nigikoresho gikora vertebral, hamwe ninyo ya kabiri ya basin-angle. Ibikoresho byo gutwara vertebral bihujwe na shitingi yoherejwe kandi bizunguruka ku isaha. Bitewe na diametre ntoya yibikoresho bya bevel ikora hamwe na diameter nini yinyo yinyo ya basine, imikorere yo kwihuta iragerwaho.
Nigute ushobora guhindura ikibazo cyumwanya ukabije wibikoresho bya basin angle:
Guhindura ibikoresho bya basin angle ntabwo ari ikibazo cyokwemererwa gusa, muri rusange, gusiba biroroshye guhinduka, cyane cyane kubera ibimenyetso byerekana. Nyuma yo gusimbuza ibikoresho byo mu nkono, banza ushyire iryinyo ryinkono cyangwa uruziga runini kumurongo utandukanye, hanyuma ukosore intebe zifata nimbuto zindabyo kumpande zombi, mubyukuri ushireho umwanya, ushyireho uruziga ruto (iryinyo ryinguni), na rito uruziga Koresha ibara ryamabara hejuru yinyo, mubisanzwe ifu yumutuku wumutuku, hanyuma uyimure mukiganza kugirango urebe ibara ryinyo yinyo, hanyuma uyihindure kugeza igihe icyapa kiri hejuru yinyo ikora kumuziga munini ari nto, ariko ntishobora kuza Kuva ku menyo. Imwe mu myanya yo guhinduranya ni uguhindura imbuto zindabyo kumpande zombi ziziga rinini, naho ubundi ni uguhindura ubunini bwa gaze inyuma yiziga rito. Naho icyuho wavuze, urashobora gukanda insinga ziyobora kuruhande rwinyo, hanyuma ugapima ubunini bwinsinga ziyobora nyuma yo kuyikuramo. Ibisabwa byihariye byo gusubira inyuma biterwa na modulus hamwe nakazi ka gare, ariko ntakibazo gihari cyo gusubira inyuma hafi 0.3 ~ 0.4mm.
