The 86746476 gear is a key power transmission component designed specifically for the Montabert HC95 hydraulic rock drill, one of the most widely used heavy-duty rock drills in mining and tunneling engineering. In high-intensity operations (e.g., drilling hard rock blast holes and tunnel anchor holes), this gear acts as a "power bridge" between the drill motor and the drill rod: it converts the motor's rotational force into stable, high-torque drill bit power, directly determining the HC95's drilling efficiency and operational stability.

1. Manufacturing Tolerance: Machined with CNC gear hobbing and grinding, the gear’s tooth profile, pitch, and backlash are controlled within ±0.02mm (matching Montabert’s original factory standards).
2. Operational Benefit: It meshes seamlessly with the HC95’s motor shaft and transmission components, eliminating "power loss" or "vibration-induced noise" during operation—ensuring consistent drill rotation speed and impact force.
3. Fit & Design: The gear’s inner bore, keyway, and mounting dimensions are 1:1 identical to the Montabert original part.
