Pre-Winder Installation Tools 

Pre-Winder Installation Tools Tool

This type of tool is ideal for installing inserts in small production runs or in areas where compressed air or electricity are not available and offers a quicker alternative to the simple hand installation tool. The tool is suitable for use when installing free running and locking inserts. The mandrel is wound into the insert which is then installed into the tapped hole. During installation the insert diameter is reduced when passing through the bottom of the prewinder

tool chamber making it easier to install. The mandrel is  removed by turning the crank in a counter clockwise direction, leaving the insert in place.
