Radius ea ho kobeha ea setsoe se selelele sa ho wellisa sa radius butt e lekana le bophara ba kantle ba phaephe ka makhetlo a 1.5, ke hore, R=1.5D. Radius ea ho kobeha ea setsoe se khutšoane sa ho wellisa sa radius butt e lekana le bophara ba kantle ba phaephe, ke hore, R=1D. Foromong, D ke bophara ba setsoe sa ho wellisa sa butt, 'me R ke radius ea ho kobeha. Haeba ho se na tlhaloso e khethehileng, setsoe sa 1.5D se sebelisoa hangata.
