The Threading Tool will cut a thread on the PTFE and Bioplast bars making it easier to screw on balls / attachments. The tool can be used for 1.2mm and 1.6mm PTFE, BioFlex and Bioplast.
To use just push the PTFE / Bioplast into the correct end of the tool for the gauge you are using and turn a few times in a clockwise direction. Turn anti clockwise to remove the bar then add your new ball.
