ABSTRACT:
The invention relates to a hand machine-tool, especially electrical shears, comprising a housing (13) provided with a tool head (14) and a grip part (15), an electric motor (18) arranged in the housing (13), a switch (22) for the electric motor (18), and a drive shaft (16) mounted in the tool head (14), transversally to the housing axis. The drive shaft can be driven by the electric motor (18) by means of a transmission (19). The hand machine-tool also comprises a rotary tool (11) that can be fixed to the drive shaft (16). The aim of the invention is to create a compact, structurally small and lightweight hand machine-tool for work without generating fatigue. To this end, a small-volume, rechargeable energy accumulator, preferably a lithium ion accumulator (20), which feeds the electric motor (18) and has a high charging capacity, is arranged in the grip part, together with an electronic plate (21) and the switch. The transmission (19) and at least part of the electric motor (18) are arranged in the tool head (14).
