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.
