Abstract
An apparatus with a motor driven material removing tool for cutting, drilling, milling, sawing or grinding of concrete, stone or the like. The apparatus comprises three spaced apart operational groups, namely a working group, a vacuum source and control group, and a driving group. The groups are mobile and interconnectable and disconnectable by hoses and electrical cables. The working group comprises an interchangeable tool, such as a drill, drive motor means for driving and advancing the tool, and a tool holding device mounted on the outside of a rigid suction bell. The vacuum and control group includes vacuum producing means and electrical and fluid control units. The driving group has at least one hydraulic pressure pump with motor means for generating the hydraulic power for driving and advancing the tool.
