I-Conical DEC (icwecwe elithuthukisiwe ledayimane), inkampani ikhiqiza amashidi ayinhlanganisela angahleliwe anobunjwa obuhlukene kanye nokucaciswa okufana ne-wedge, iphiramidi elingunxantathu (iphiramidi), ikhoni encishisiwe, i-Benz engunxantathu, kanye nesakhiwo se-arc esiyisicaba. Ubuchwepheshe obuyinhloko beshidi le-polycrystalline diamond composite liyamukelwa, 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 ayinhloko/ayisisizi, amazinyo egeji eyinhloko, amazinyo omugqa wesibili, njll.
