摘要：
An apparatus for percussively milling slots in rock or the like includes a flat disk-like radial boring tool mounted on a drive shaft which is rotated slowly against the work while being driven percussively and radially outwardly toward the work in the neighborhood of, for example, forty times for every revolution of the tool.
