Matrix Body PDC Bits vs. Steel Body PDC Bits

Haeba u sebelitse ho cheka nako efe kapa efe, mohlomong u kile oa utloela ka likotoana tsa PDC. PDC e emetse "polycrystalline diamond compact," e hlalosang motsoako oa thepa o etsang bokaholimo ba likotoana tsena. Ka bobeli Matrix Body PDC le Steel Body PDC li entsoe ka motsoako ona.
