Abstract

The hydraulic milling tool (0), for attachment to a construction or mining machine, has at least one cutting roller (11), at least one flywheel (12) to take up kinetic energy, and at least one hydraulic motor (6) to rotate the cutting roller and flywheel. The flywheel is rotated at a higher rotary speed than the cutting roller, to give the cutter an increased moment of inertia. A gearing (2) sets a fixed rotary speed ratio between them.
