Hand-held power tool, in particular drill

In an electric hand-tool, especially a drill, with a casing (10), an electric motor (15) contained therein with a motor shaft (16) parallel to the casing axis and a working spindle (18) driven by the electric motor (15) via a reduction gear (17), the casing (10) is divided along a separating plane (21) for the purpose of conversion from straight to angular drilling and facilities for relative pivoting between the front part (101) of the housing containing a bearing (19) for the working spindle (18) and the rear part (102) of the casing containing the electric motor (15) are provided in such a way that the working spindle (18) projecting from the front part (101) of the casing may assume any angle between 0 and 90 DEG or more in relation to the motor shaft (16). A manually lockable and/or releasable engagement lock holds the two parts of the casing (101, 102) in the selected position. A power transmission which is rigid in rotation from the motor shaft (16) to the working spindle (18) in any angular position of the casing sections (101, 102) is provided in the reduction gear (17).
