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.

Core Advantages
1. Impact Performance: The shank’s hardened surface resists indentation and deformation, even when drilling dense granite or basalt for 24/7 continuous shifts.
2. Manufacturing Tolerances: CNC-turned and ground to ±0.005mm on all critical surfaces (inner bore, outer diameter, and contact faces)—matching Montabert’s original factory specs exactly.
3. Sealing Design: The shank’s stepped profile (visible in product images) forms a tight seal with the HC95’s housing, preventing rock debris and hydraulic fluid leaks between components.
4. Mounting Design: The shank’s snap-fit or bolt-on profile (matching the HC95’s housing) requires no specialized tools for installation—trained technicians can replace it in ≤15 minutes during routine maintenance.
Application Scenarios
The 86770195 Retainer Shank is essential for:
- Montabert HC95 rock drills drilling hard-rock blasting holes (mining operations, up to 30m depth).
- HC95 units performing tunnel anchor/support hole drilling (infrastructure projects, dense rock formations).
- HC95 maintenance/overhaul (replacing worn, deformed, or misaligned original retainer shanks).
