Abstract

A pneumatic reciprocating tool having increased durability against impact by a piston that reciprocates. The pneumatic reciprocating tool has a tubular housing (12), first and second pistons (14, 16) placed in the housing so as to be displaceable in the axial direction of the housing, and a tool installation member (18) extending forward from the second piston. Compressed air from a compressed air source is supplied between the first and second pistons to drive the first and second pistons to rearward and forward, respectively. A braking member (22) is placed in front of the second piston. The braking member has a piston braking chamber (24) having an opening facing rearward. The braking member receives from the opening a front part of the second piston that is driven and displaced forward a predetermined distance by the compressed air, and thus the braking member brakes and stops the second piston by air in the piston braking chamber compressed by the front part of the second piston.
