Polycrystalline Diamond (PCD) idhaimondi rekugadzira. PCD chishandiso chinopa yepamusoro kupfeka kuramba mune zvakanyanya abrasive zvinhu.
PCD Carbide isa bhatani bhatani tinoridaidza kuti PDC Bhatani Bit, rinowanzo shandiswa kuDTH Bit, RC Bit, Pamusoro Hammer Bit. Iwo mabheti anoshandiswa kuchera matombo, migodhi uye geological exploration.
Kune imwe Polycrystalline Diamond Compact bit iyo inonziwo PDC Bit ine 3-7 mapapiro emafuta uye gasi indasitiri. Asi hatiziri kutaura pano.
Iyo PDC bit ine PCD carbide ine nguva yakareba yekushandira hupenyu kupfuura tungsten carbide bit, i.e, ingangoita 5-7 nguva yakareba hupenyu. Saka iri kuramba ichinyanya kufarirwa munzvimbo yekushandira migodhi.
