The tool i.e. hand-held electric chisel (1), has a bit socket (6) holding a chiseling bit (7) that is movable along a movement axis (3). A magneto-pneumatic striking mechanism (2) includes a first magnet coil (46), a ring magnet (42) and a second magnet coil (47) arranged consecutively in a striking direction (5). The mechanism has a striker (4) and a striking block (13) arranged consecutively in the striking direction, and an air spring (23) acting upon the striker in the striking direction, where the ring magnet is a permanent magnet and magnetized radially relative to the movement axis. The striker and striking block are made of a soft-magnetic material. |
