A handheld working tool for treating a workpiece comprises a tool nose provided for contacting the workpiece at a working point, and an indicator provided for indicating a reference point on a surface of the workpiece at a predetermined distance to the working point when the tool nose contacts the workpiece at the working point.

The present disclosure is directed to performing work on a working surface based on a desired path using a working member. The disclosed system advances the working member with respect to the desired path using a first positioning system and a second positioning system. The first positioning system comprises a frame and actuators operable to advance the working member with respect to a portion of the desired path within an adjustment region. The second positioning system comprises actuators operable to move the frame. By moving the frame using the second positioning system, the first positioning system advances the working member with respect to a portion of the desired path that was outside the adjustment region before the frame was moved.

A power tool stand comprises a base; a projecting frame connected to the base; and a power tool carriage moveably mounted on the projecting frame. The power tool carriage comprises a first interface arranged to electrically connect with a removeable power tool and a second interface in electrical connection with the first interface and arranged to electrically connect with a removeable battery.

A device for ascertaining the orientation of a drill relative to a plane, the device being capable of being connected to the drill, the device having a laser distance measuring unit by which, from a prespecified position relative to the plane, a first distance to a first point in the plane and a second distance to a second point in the plane can be measured, and having an evaluation unit that is configured such that on the basis of the first distance and the second distance the orientation of the device relative to the plane can be ascertained.

A positioning aid is disclosed for a core drilling machine, having a core drill for creating a hollow-cylindrical drill hole. The positioning aid includes a light source for creating a centring pattern on a workpiece. The positioning aid is fastened in a releasable and centered manner to the core drilling machine. The positioning aid may include a laser pointer, which is releasably fastened to a centring pin.

A method of automated spatial worksite referencing of a networked electronic measuring device with awareness of a rough location information of itself at a worksite location. The method includes querying a database for construction plan information about the rough location and its vicinity and about an actual work progress, computing an actual-state nominal spatial information at the rough location and its vicinity, automatically determining of a fine location of the networked electronic measuring device at the worksite location, by at least one iteration of: automatically determining a measurement point in the vicinity and measuring the measurement point using measurement functionality of the device, and then automatically assimilating the measurement point to the actual-state nominal spatial information and thereby determining the fine location information. When a desired level of accuracy of the determined fine location is not reached, performed another iteration with another additional measurement point is performed.

A device for determining a penetration depth in a drilled hole which is drilled into a workpiece (W) from a workpiece surface (WO) with a drill of a drilling machine. The device contains at least one light source for projecting a light field is provided onto a workpiece (W) to be processed by the drilling machine. The light source is positioned with respect to the drilling machine in such a way that a centre axis (L) of the light source runs at an angle (a) with respect to a central axis (L) of the drilling machine, and at least a first blocking element for partially covering the light source is provided, said blocking element forming a reference on the light field.

A projection system includes a projection device that projects drawings individually onto a plurality of work spots in a work site. The projection device includes a driver that changes an orientation of the projection device. When drawings are individually projected onto a first work spot and a second work spot in a stated sequence, and the second work spot is outside a projection angle that is projectable by the projection device, the driver changes the orientation of the projection device to include the second work spot within the projection angle after work at the first work spot is finished. The first work spot and the second work spot are included in the plurality of work spots.

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.

An auxiliary device for power tool having a power tool and rangefinder, the rangefinder being attached to/built in the power tool for distance measurement during the operation. The rangefinder includes at least a distance sensor set toward the operation direction of the power tool, a screen for showing the distance data of the distance sensor, and a control circuit connecting with the distance sensor and the screen for calculating the distance and displaying the distance data on the screen. A case, level meter, metal detector, and light sensor are also provided.
