86770195 Retainer Shank for Montabert HC95 Rock Drill

The 86770195 Retainer Shank is a precision positioning and load-bearing component at the core of the Montabert HC95 rock drill’s shank assembly. It serves as the critical interface between the drill’s impact piston and the drill bit shank, maintaining perfect axial alignment during high-frequency percussion cycles, while absorbing axial thrust loads and protecting internal mechanisms from wear and misalignment.

Manufactured to Montabert’s exact OEM specifications, this retainer shank guarantees a seamless drop-in fit with the HC95’s front guide and shank assembly, preserving hydraulic pressure integrity and operational stability. In harsh underground mining, tunneling, and quarrying environments—where dust, moisture, and extreme vibration are constant—it resists impact fatigue and abrasive wear, directly extending the service life and drilling efficiency 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 86770195 Retainer Shank is an indispensable replacement part for your Montabert rock drill in all core operational scenarios:

• Positioning the drill bit shank in Montabert HC95 rock drills during underground mining blasting hole drilling (up to 40m depth) in hard-rock formations like granite and basalt.
• Centering the shank assembly in Montabert HC95 rock drills used for tunnel anchor and support hole drilling in wet, dusty infrastructure construction projects.
• Protecting internal components of Montabert HC95 rock drills during quarrying operations for stone cutting, rock excavation, and pre-splitting tasks.
• Restoring factory-spec impact performance during full overhauls or shank assembly replacement of Montabert rock drills.
