Abstract: A pneumatic cutting tool has an extended body length so it can be operated by a pair of hands to facilitate the operation and holding thereof The body length can be increased using an extension cylinder and extension kit. The tool also has a handle mounted onto the periphery of the extended body length. The handle can be moved to any suitable axial and radial position on the body, and secured by tightening a threaded rod in the handle.

Abstract: A hand held hole punching device having a shaft and a main body with a device for axially moving the shaft in a reciprocating motion. The tool head is connected to the shaft and includes a fixed portion fixed to the main body to slidably engage the shaft so that the shaft is permitted to slide axially relative to the fixed portion. Also, a movable portion is fixed to the shaft so that the movable portion moves axially with the shaft and the movable portion and the fixed portion cooperatively define at least two hole punchers. Each hole puncher has a punch pin that is different from a punch pin of any other hole puncher on the tool head.
