摘要:
A power tool (1) having a striking means (5), by which a percussive tool (2) that can be driven at least partially along an axis (A) struck directly and having a flushing bore (4) extending at least partially longitudinally through a tool shank (3), and having a flushing head (6) having a radially inwardly open transverse bore hole (8) connected in a flow-through fashion with a fluid channel (7). The flushing head (6) has at least one hollow cylindrical sleeve-like guide surface (9), which is fitted for an insertion end (10) of the striking tool (2). The striking means (5) sealed by a seal (11a, 11b) is cup-like. The striking means (5) is moveably guided and made fluid tight by the seal (11a, 11b) to embrace the machine-side part of the insertion end (10) having the machine-side open flushing bore (4).
