I-DH1216 Idayimane elincishisiwe leshidi eliyinhlanganisela
Ishidi eliyinhlanganisela yedayimane elinezingqimba ezimbili elimise okwe-frustum lamukela uhlaka lwangaphakathi nangaphandle lwezingqimba ezimbili ze-frustum nendandatho yekhoni, okunciphisa indawo yokuxhumana nedwala ekuqaleni kokusika, futhi i-frustum nendandatho yekhoni kwandisa ukumelana nomthelela.Indawo engaseceleni yokuxhumana incane, okwenza ngcono ukucija kokusika kwamadwala.Iphuzu lokuxhumana elingcono kakhulu lingakhiwa ngesikhathi sokumba, ukuze kuzuzwe umphumela wokusetshenziswa okungcono kakhulu futhi kuthuthukiswe kakhulu impilo yesevisi ye-drill bit.
