86770195 Retainer Shank for Montabert HC95 Rock Drill Accessories

The 86770195 Retainer Shank is a critical load-bearing & alignment component of the Montabert HC95 rock drill—installed between the drill’s impact piston and drill bit to:

• Transmit Impact Force: Transfer the HC95’s 18 kJ per-cycle impact energy from the piston to the drill bit, ensuring efficient rock fragmentation.
• Secure Component Alignment: Maintain precise centering of the drill bit and piston during high-vibration drilling, preventing premature wear of internal parts.
• Protect Internal Components: Act as a buffer against rock debris and hydraulic fluid contamination, shielding the piston and transmission system.
