A robotic drill system and a method of drilling with a robotic drill system. This includes inserting a tool head of the robotic drill within a hole of a drill template along an initial insertion trajectory with a robotic manipulator arm that is moved by at least one robotic actuator for causing robotic insertion of the tool head. In response to sensing binding of the tool head to a wall of the hole while inserting the tool head along the initial insertion trajectory, the disclosure includes stopping robotic insertion of the tool head and activating a self-centering device of the tool head to reorient the tool head to a corrected alignment of the tool head axis relative to the hole. The self-centering device may include an expandable collet.

A method for determining a recommendation of a gear to be engaged for a core drill. In the method, it is possible to use for example a drop in a rotational speed of a core bit of the core drill in the event of sudden deactivation of the motor of the core drill in order to determine the diameter of the core bit. Alternatively, the diameter of the core bit can be determined when the drill is started up or turned on. The diameter of the core bit is then used as the basis for the recommendation of the gear to be engaged. In a second aspect, the invention relates to a core drill with which the method can be carried out.

A method includes drilling a first aperture in a panel that extends between a panel first surface and a panel second surface. The first aperture projects into the panel along a first centerline from the panel first surface. The first centerline is angularly offset from the panel first surface by a first angle. A first tool is arranged with the panel. The first tool includes a support structure, a locator and a drill guide. The locator is mounted to the support structure and projects into the first aperture. The drill guide is mounted to the support structure and is arranged adjacent the panel second surface. A second aperture is drilled in the panel using the drill guide. The second aperture projects into the panel along a second centerline from the panel second surface to the first aperture. The second centerline is coaxial with the first centerline.
