Mazino edhaimondi anoumbwa (DEC) anogona kukamurwa kuita: dhaimondi rinoumbwa neconical mazino, madhaimondi anoumba mazino akatenderedza, madhaimondi anoumba conical spherical mazino, dhaimondi akaumbwa mazino ovoid, dhaimondi composite wedge mazino, dhaimondi composite akafuratira mazino epamusoro maererano nechitarisiko uye basa. etc.
Inoshandiswa zvakanyanya muinjiniya yekuchera uye minda yekuvaka senge roller cone bits, pasi-the-hole bits, engineering yekuchera maturusi, uye kupwanya michina. Panguva imwecheteyo, nhamba huru yezvikamu zvinoshanda zvePDC bit zvinoshandiswa, senge mazino anonwisa, mazino epakati, mazino egeji, nezvimwe.
