The invention relates to an electric hand-held power tool (2). Said compact and easy to handle hand-held power tool (2) comprises an electric drive motor (6), a tool holder (18) that is rotationally driven by said drive motor (6) via a drive mechanism (12, 16) and that is configured in order to accommodate a tool (46, 48, 50) suitable for hammer drilling or hammering, or a tool (46, 48, 50) suitable for rotatingly drilling or a tool (46, 48, 50) suitable for screwing, in addition to a pneumatic percussion mechanism (20) for applying strikes onto a tool (46) inserted into the tool holder (18). According to the invention, the tool holder (18) includes a shank portion (52, 54) for the tool (46, 48, 50) and a holding sleeve (68) with the two end portions thereof to be opened. The inner circumferential surface (88) of the holding sleeve (68) is provided with at least eight planar circumferential surface sections (88n, 88o, 88p, 88q, 88r, 88s, 88t, 88u) in the circumferential direction. Each pair of adjacent circumferential surface sections (88n, 88o, 88p, 88q, 88r, 88s, 88t, 88u) form an angle of 120 degrees.
