The 86747664 Strike Piston is the core impact component of the Montabert HC95 hydraulic drifter—responsible for converting hydraulic pressure into the high-force impact needed to break hard rock (e.g., granite, basalt). In every drilling cycle, this piston accelerates and strikes the drill shank, delivering up to 18 kJ of impact energy per hit: without it, the HC95 cannot perform its primary rock-drilling function.

1. Hydraulic Efficiency: The piston’s smooth, polished surface (Ra 0.1 μm roughness) minimizes friction with the cylinder, reducing hydraulic energy loss and maintaining consistent impact force.
2. Seal Groove Precision: The integrated seal grooves (visible on the piston body) are machined to exact Montabert specs, ensuring a tight fit with hydraulic seals—eliminating internal fluid leaks that reduce impact power.
3. Wear-Resistant Coating: The piston’s working surfaces are treated with a tungsten carbide-reinforced coating (on the impact face) to reduce wear from repeated contact with the drill shank.
4. Impact Face Profile: The piston’s tapered impact face is engineered to concentrate force on the drill shank, maximizing energy transfer to the rock (rather than dispersing it as vibration).
