The 86747664 Strike Piston is the core impact energy-generating component of the Montabert HC95 rock drill, serving as the "heart" of the drill’s percussion system. This precision-machined piston converts high-pressure hydraulic energy into linear impact force, delivering up to 12 kJ of energy per cycle to the drill bit shank, enabling efficient penetration into hard rock formations.

Manufactured to Montabert’s exact factory specifications, this strike piston guarantees a seamless drop-in fit with the HC95’s cylinder and valve assembly, preserving hydraulic pressure integrity and impact performance. In harsh underground mining, tunneling, and quarrying environments—where dust, moisture, and extreme vibration are constant—it resists wear, fatigue, and thermal stress, directly determining the drilling power and service life of your Montabert rock drill.

• Genuine Montabert Precision for Perfect HC95 Compatibility
• High-Impact Durability for Mining Operations
• Hydraulic Sealing & Debris Protection
• Optimized Design for Maintenance Efficiency

The 86747664 Strike Piston is the most critical replacement part for your Montabert rock drill in all core operational scenarios:

• Delivering high-impact energy to Montabert HC95 rock drills during underground mining blasting hole drilling (up to 40m depth) in hard-rock formations like granite and basalt.
• Sustaining percussion performance in Montabert HC95 rock drills used for tunnel anchor and support hole drilling in wet, dusty infrastructure construction projects.
• Maintaining impact power in Montabert HC95 rock drills during quarrying operations for stone cutting, rock excavation, and pre-splitting tasks.
• Restoring factory-spec percussion performance during full overhauls or cylinder replacement of Montabert rock drills.
