Multi-Use Punch

Abstract

A multi-use punch has a core, a handle, a chuck and at least one tool head. The core is metal and has a chuck end. The handle is mounted around the core and has a butt end having at least one chamber and a cap. The cap is detachably mounted on the butt end of the handle. The chuck is mounted on the chuck end of the core and has a detent. The tool head is alternately mounted in the chuck end of the core and the chamber of the handle and has a detent corresponding to and being selectively held securely by the detent of the chuck. Each tool head can be easily changed so the punch can be easily and conveniently used for multiple tasks.
