The 86737376 Shank Stop is a precision positioning and load-limiting component exclusively engineered for the Montabert HC25 rock drill. As a genuine Montabert original part, it acts as the mechanical "stop" for the drill bit shank, controlling its axial travel and preventing over-penetration during impact cycles. This critical component ensures the drill bit is precisely positioned to receive maximum impact energy from the piston, while protecting the internal mechanism of your Montabert rock drill from damage caused by excessive force or misalignment.

Manufactured to Montabert’s strict factory specifications, this shank stop guarantees a seamless drop-in fit with the HC25’s housing. It maintains the drill’s factory-calibrated performance, making it essential for keeping your Montabert rock drill running reliably in harsh mining and tunneling environments.

• Genuine Montabert Precision for Montabert Rock Drill
• High-Impact Durability for Demanding Montabert Rock Drill Use
• Precision Positioning & Load Control for Montabert Rock Drill
• Debris Resistance for Harsh Montabert Rock Drill Environments

The 86737376 Shank Stop 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 shank stops.
