The 86715414 Piston is the core impact component of the Montabert HC25 rock drill. As the heart of your Montabert rock drill, it converts high-pressure hydraulic fluid into up to 12 kJ of impact energy per cycle, delivering the force needed to break dense rock formations like granite and basalt.

This genuine Montabert part is precision-engineered to the exact factory specifications of the HC25, ensuring a seamless drop-in fit and preserving the drill’s original performance. It is critical for maintaining consistent impact power and extending the service life of your Montabert rock drill in harsh mining and tunneling environments.

• Genuine Montabert Engineering for Unmatched Compatibility
• Ultra-High Impact Durability for Demanding Montabert Rock Drill Use
• Precision Hydraulic Sealing for Montabert Rock Drill
• Optimized Geometry for Montabert Rock Drill Performance

The 86715414 Piston is indispensable for keeping your Montabert rock drill operational in the most critical applications:

• Powering Montabert HC25 rock drills for underground mining blasting hole drilling (up to 25m depth) in hard-rock deposits.
• Driving Montabert HC25 rock drills for tunnel anchor and support hole drilling in infrastructure projects.
• Enabling Montabert HC25 rock drills to perform quarry stone cutting and pre-splitting drilling tasks.
• Restoring full impact power during overhauls and routine maintenance of Montabert rock drills—replacing worn, deformed, or damaged original pistons.
