Abstract (en)
[origin: US6203113B1] A rotatable cutting drum to be mounted on a machine for mining or for milling a surface such as a roadway. The drum is equipped with a set of movable bits or chisels which impact on the surface to be cut. The movable bits or chisels are impacted by pendulums mounted on a rotating cylinder mounted inside of the drum so that a percussive force is generated to assist cutting.
