Abstract
A pneumatic drill for concrete breaking etc. with an outer cylinder and a crank driven piston, has the outer cylinder (12) constructed with a lower cover (15) with an axial hole (18) which is used as a guide for the shaft (17) of the impacting tool (16). The impacting tool (16) protrudes from the device and has an annular fitting (31, 32) with a spiral spring (43) between this (31, 32) and the lower cover (15). An outer sliding housing (13) is attached around the lower section of the device and contains an outer spiral spring (42) which lies outside the inner spring (43) resting on the annular fitting (31, 32).
