101148259/86605920 Spline Shank for Montabert HC50 Rock Drill Parts

The 101148259 / 86605920 Spline Shank is a core power transmission component for the Montabert HC50 rock drill, serving as the critical interface between the driving gear and the drill bit. This precision-machined component transfers both rotary torque and impact energy from the drill’s internal mechanism to the drill bit, enabling efficient hard-rock penetration in mining, tunneling, and quarrying operations.

Manufactured to Montabert’s exact factory specifications, this spline shank guarantees a seamless drop-in fit with the HC50’s gearbox and chuck assembly, preserving torque transmission efficiency and impact alignment. In harsh underground environments—where dust, moisture, and extreme vibration are constant—it resists wear and fatigue, directly extending the service life and reliability of your Montabert rock drill.
