PCT No. PCT/DE92/00360 Sec. 371 Date May 17, 1993 Sec. 102(e) Date May 17, 1993 PCT Filed May 2, 1992 PCT Pub. No. WO92/20491 PCT Pub. Date Nov. 26, 1992.In an electric hand tool, particularly a drill, with a housing, an electric motor which is received in the housing and has a motor shaft parallel to the housing axis, and with a work spindle which is driven by the electric motor via a transmission gearing, the housing is divided along a dividing plane for the purpose of switching from straight drilling to angular drilling and it is provided that the front housing part containing a bearing for the work spindle and the rear housing part containing the electric motor can swivel relative to one another in such a way that the work spindle projecting out of the front housing part can occupy any angle between 0 DEG and 90 DEG or more relative to the motor shaft. A catch lock which can be unlocked and/or locked manually stops the two housing parts in the selected swivel position. A torsionally rigid transmission of force from the motor shaft to the work spindle is realized in every swivel position of the housing parts in the transmission gearing.
