The 86333838 Striking Piston is the core impact component of the Montabert HC50 rock drill, serving as the mechanical "heart" that converts high-pressure hydraulic fluid into powerful impact energy (up to 10 kJ per cycle). As a genuine OEM part, it directly transfers force to the drill bit, enabling efficient penetration of hard rock formations like granite and basalt in mining, tunneling, and quarrying operations.

Manufactured to Montabert’s exact factory specifications, this piston guarantees a seamless drop-in fit with the HC50’s cylinder and hydraulic system. It preserves the drill’s original impact power and operational precision, while resisting wear and fatigue in the harshest mining environments. For any Montabert rock drill owner, this is the only reliable choice to restore factory performance during maintenance or overhaul.

• Genuine Montabert Precision for Perfect HC50 Compatibility
• Heavy-Duty Structural Durability for Montabert Rock Drill Operations
• Hydraulic Sealing & Debris Protection for Montabert Rock Drill
• Optimized Design for Montabert Rock Drill Maintenance Efficiency
