The 86334125 Shank Stop is a precision positioning and load-limiting component exclusively engineered as a genuine OEM part for the Montabert HC50 rock drill. As the mechanical "stop" for the drill bit shank, it controls axial travel and prevents over-penetration during impact cycles, ensuring the drill bit receives maximum impact energy while protecting internal mechanisms from damage.

Manufactured to Montabert’s exact factory specifications, this shank stop guarantees a seamless drop-in fit with the HC50’s housing, preserving the drill’s original impact performance and operational stability. In harsh mining, tunneling, and quarrying environments—where dust, moisture, and extreme vibration are constant—it maintains precise alignment and resists wear, directly extending the service life of your Montabert rock drill.

• Genuine Montabert Precision for Perfect HC50 Compatibility
• High-Impact Durability for Mining Operations
• Hydraulic Sealing & Debris Protection
• Optimized Design for Maintenance Efficiency

The 86334125 Shank Stop is an indispensable replacement part for your Montabert rock drill in all core operational scenarios:

• Positioning the drill bit shank in Montabert HC50 rock drills during underground mining blasting hole drilling (up to 30m depth) in hard-rock formations like granite and basalt.
• Limiting shank travel in Montabert HC50 rock drills used for tunnel anchor and support hole drilling in wet, dusty infrastructure construction projects.
• Protecting internal components of Montabert HC50 rock drills in quarrying applications 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.
