Ubu isosiyete irashobora gukora impapuro zidafite gahunda zifite imiterere itandukanye kandi itandukanye nkubwoko bwa wedge, ubwoko bwa cone triangulaire (ubwoko bwa piramide), ubwoko bwa cone bwaciwe, ubwoko bwa mpandeshatu ya Mercedes-Benz, hamwe nuburyo bwa arc. Tekinoroji yibanze ya polycrystalline ya diamant igizwe nimpapuro zemejwe, kandi imiterere yubuso irakanda kandi irashirwaho, ifite aho igarukira kandi ubukungu bwiza. Yakoreshejwe cyane mu gucukura no gucukura amabuye y'agaciro nka diyama, amabuye ya roller, amabuye y'agaciro, n'imashini zimenagura. Muri icyo gihe, birakwiriye cyane cyane kubice byihariye bikora bya PDC bitobora, nk'amenyo nyamukuru / afasha, amenyo nyamukuru yo gupima, amenyo yumurongo wa kabiri, nibindi, kandi arashimwa cyane nisoko ryimbere mu gihugu ndetse n’amahanga.
Amenyo ya diyama. Urupapuro rudasanzwe rwa diyama rugizwe no gucukura peteroli na gaze, imiterere yihariye, ikora ahantu heza ho gukata kugirango haboneke ingaruka nziza yo gucukura amabuye; bifasha kurya muburyo, kandi bifite kwihanganira umufuka wibyondo.
