[0013]The multi-use punch in accordance with the present invention 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. The butt end of the handle has 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.

Problems solved by technology

However, the conventional punch (60) must be changed for different jobs, therefore, multiple punches (60) must be carried, which is inconvenient.
Furthermore, the conventional punch (60) cannot be used as a different tool, so is carried exclusively for punching holes and pins or nails.
