Hiki ke hoʻokaʻawale ʻia nā niho hui daimana (DEC) i: daimana composite conical niho, daimana composite spherical niho, daimana composite conical spherical niho, daimana composite ovoid niho, daimana composite wedge niho, daimana composite flat top niho ma ke ano o ka helehelena a me ka hana. etc.
Hoʻohana nui ʻia ia i ka ʻenekinia ʻeli a me nā kahua kūkulu e like me ka roller cone bits, down-the-hole bits, engineering drilling tools, and crushing machinery. I ka manawa like, hoʻohana ʻia ka nui o nā ʻāpana hana kikoʻī o ka bit PDC, e like me nā niho haʻalulu, nā niho waena, nā niho gauge, etc.
