Rethreading Set External: 4-38mm | Internal 8-32mm (60° M. MF. UNC. etc.)
The BAER thread restorer for external and internal thread is an indispensable tool for professional thread maintenance.
The handy thread restorer restores old threads efficiently and precisely without changing the original structure. Regardless of the thread pitch, the BAER 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 screw tap, except that it cannot be used to cut a completely new thread and several dimensions can be processed with one tool.
The BAER 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 suitable for the metric sizes M 4 - 38 mm (external thread) and M 8 - 32 mm (internal thread) with a thread angle of 60° and is also compatible with the imperial sizes 5/32'' - 1.1/2'' (external thread) and 5/16'' - 1.1/4'' (internal thread) with a thread angle of 60°. Both coarse thread and fine threads can be recut.
This means that the BAER tap covers a wide range of requirements and proves to be a reliable partner for every workshop and every craftsman. The thread repair is simple and efficient due to the universal tool and is therefore a reliable partner for every workshop and every craftsman.

Thread restoration – Instructions
Repairing external threads - Step 1
Turn the handle (A) to raise the floating blades (B). Place the restorer over the thread to be repaired.
Repairing external threads - Step 2
Turn the handle (A) to lower the floating blades into the grooves of the thread and tighten by hand only.
Repairing the external thread - Step 3
Turn the restorer in the respective direction.
Internal thread repair - step 1
Turn the knurled knob (K) to fully retract the blade (B) into the housing (H). Insert the restorer into the hole or threaded hole to be repaired.
Internal thread repair - step 2
Turn the knurled knob (K) to extend the blade (B) into a fluted thread in an undamaged area and tighten by hand only.
