PCD (Stratacut) drill bits /chisel are mainly used in not too hard, low abrasive formations, where the PCD (Stratacut) drill bits achieve high drilling progress with low wear due to their relatively large, highly wear resistant cutting bodies. The cutting bodies of the PCD drill bit (Stratacut plates) are tungsten carbide discs that are coated with a layer of polycrystalline diamond and are inserted transversely to the crown lip.
