Inkampani ivelisa amaxwebhu non-planar composite iimilo ezahlukeneyo kunye neenkcukacha ezifana uhlobo wedge, uhlobo cone engunxantathu (uhlobo lwephiramidi), uhlobo cone truncated, uhlobo Mercedes-Benz elingunxantathu, isakhiwo arc tyaba, njl Ubugcisa engundoqo polycrystalline diamond sheet composite yamkelwa, kwaye isakhiwo somphezulu sicinezelwe kwaye senziwe, esinomgca obukhali kunye noqoqosho olungcono. Isetyenziswe ngokubanzi kwindawo yokomba kunye nemigodi efana ne-diamond bits, ii-roller cone bits, iibits zemigodi, kunye noomatshini abatyumzayo. Kwangaxeshanye, ifaneleke ngokukodwa kwiindawo ezithile ezisebenzayo zePDC drill bits, njengamazinyo aphambili/ancedisayo, amazinyo aphambili okulinganisa, kunye namazinyo omqolo wesibini.
