The thread restorer for external threads is an indispensable tool for professional thread maintenance.
 
Nes thread repair restores old threads efficiently and precisely without changing the original structure. Regardless of the thread pitch, the thread restorer removes rust with its robust, hardened cutting blades and cuts the old thread at the head end. The restorer thus has a similar function to a die, except that it cannot be used to cut a completely new thread and several dimensions can be processed with one tool.
 
Nes thread restorer is characterised by its simple handling, which makes it unnecessary to align or measure the thread. Due to the possibility of clockwise and anti-clockwise rotation, threads can be re-tapped flexibly. 
 
The tool is applicable for metric and inch sizes with 55° and 60° thread angles. Both coarse thread and fine threads can be recut with it.
