A device system with a device stand, a drilling device arranged displaceably on the device stand for carrying out drilling and a feed device for displacing the core drilling device along the device stand. The feed device has a manual feed device, designed for example as a handwheel or a lever, and the device system has a control device for evaluating measured values. The feed device or the manual feed device e has a sensor for determining measured values, the measured values being used for evaluation and transmitted to the control device, and a starting point and/or an end point of the drilling being detected by the control device through a sudden change in drilling parameters. In a second aspect, the invention relates to a method for determining a depth of a bore, the bore being produced with the proposed device system.

A device and system for a rotary boring tool that enables a user to visually align the tool with respect to a target worksurface is disclosed. The alignment system includes a worksurface alignment device that is mounted onto the non-rotating portion of a rotary boring tool that includes one or more focused light sources, such as a laser, that projects a linear or nonlinear shaped beam and produces a visible pattern on the worksurface that indicates alignment or misalignment of the rotary boring tool with respect to the worksurface. Systems optionally includes a user display that works independently or in combination with one or more sensors to provide additional information about the rotary boring operation, and a wireless communication device that is enables wireless communication with other computing devices directly or through a network of computing devices.
