A mechanical concrete drill system is provided which is capable of drilling holes in concrete curbs, walls, and the like, while being permanently mounted to a truck. A hydraulic lift system contained in the truck moves the drill system vertically, so that the drill can be operated in various vertical positions. The drill system is conveniently stored in the truck for movement to other drill sites.
