A damping apparatus for a reciprocating pneumatic tool mainly includes a cylindrical damper. The damper has a front opening and an enlarged rear end. The front opening is attached to a cylinder of the reciprocating pneumatic tool. A damping segment is formed between the front opening and the enlarged rear end of the damper. A spiral slot is defined longitudinally through the enlarged rear end of the damper. Several slots are defined parallel and transversely in the damping segment of the damper and communicate with the spiral slot. The damping segment has gaps arranged longitudinally by the slots such that the structure has high internal damping to attenuate shock that is caused by return movement of a piston in the cylinder. Consequently, a user holding the pneumatic tool can feel comfortable.
