A pneumatic chisel includes a housing having a double-acting pneumatic cylinder in which a piston including a chisel is movably arranged along a longitudinal axis. The cylinder has a work-side section and a return-side section. The return-side section includes a damping portion and a pressure-equalization opening. The work-side section includes an end-position damping member and a compressed air connection. A compressed air reservoir is connected to the return-side section of the cylinder. A chisel guide housing includes a sealing air chamber. The piston is constructed as one piece with the chisel.
