Use this tool with your drill press for clean, pro-quality installation of string ferrules
Press string ferrules quickly, with real control so they fit exactly flush with the surface of the guitar
One end of this installation tool fits the large ferrules that hold string ball ends on the back of a guitar
The other end of the tool fits the mini string-thru ferrules used on the tops of some guitars
Each end of the tool has an index pin that aligns the ferrule and keeps it square to the guitar body during installation
