Wytrzymałe Wiertło PDC 222 Mm Do Bardzo Twardych Formacji Skalnych

Follow the narrative to see how small design choices affect everyday performance. In this video, we demonstrate the 8 3/4in 222mm PDC drill bit engineered for super hard rock formations. Watch as we explain the optimized profile that ensures even load distribution, showcase the high-quality PDC cutters on the shoulder for enhanced wear resistance, and walk through the special backup cutter layout that improves durability while maintaining bit aggression. See how features like the 0.8mm relieved gauge and dual row cutting structure contribute to increased footage and reduced ring-out risk in demanding oil drilling applications.
