Polycrystalline Diamond (PCD) ke daemane ea maiketsetso. Sesebelisoa sa PCD se fana ka khanyetso e phahameng ea ho apara ka thepa e senyang haholo.
PCD Carbide kenya konopo hanyane re e bitsa PDC Button Bit, hangata e sebelisetsoa DTH Bit, RC Bit, Top Hammer Bit. Likotoana tseo li sebelisetsoa ho chekoa ha majoe, ho rafa le ho hlahloba libaka.
Ho na le karolo e 'ngoe ea Polycrystalline Diamond Compact eo hape e bitsoang PDC Bit e nang le mapheo a 3-7 bakeng sa indasteri ea oli le khase. Empa ha se seo re se buang mona.
PDC bit e nang le PCD carbide e na le nako e telele ea ho sebeletsa bophelo bohle ho feta tungsten carbide bit, ke hore, nako e ka bang 5-7 nako e telele ea bophelo. Ka hona e ntse e tuma haholo sebakeng sa mosebetsi oa merafo.
