Le nkampani ikhiqiza amashidi ayinhlanganisela angewona amapulani anobunjwa obuhlukene kanye nokucaciswa okufana nohlobo lwe-wedge, uhlobo lwekhoni engunxantathu (uhlobo lwephiramidi), uhlobo lwe-cone oluncishisiwe, uhlobo lweMercedes-Benz elingunxantathu, isakhiwo se-arc esiyisicaba, njll. Ubuchwepheshe obuyinhloko beshidi eliyinhlanganisela yedayimane le-polycrystalline iyamukelwa, futhi isakhiwo esingaphezulu siyacindezelwa futhi sakhiwe, esinomkhawulo obukhali wokusika kanye nomnotho ongcono. Isetshenziswe kakhulu ezindaweni zokumba nezimayini ezifana nezingcezu zedayimane, izingcezu ze-roller cone, izingcezu zezimayini, kanye nemishini yokuchoboza. Ngesikhathi esifanayo, ifaneleka ngokukhethekile izingxenye ezithile zokusebenza ze-PDC drill bits, njengamazinyo amakhulu/asizayo, amazinyo egeji eyinhloko, namazinyo omugqa wesibili.
