Tang Break Tool No. 13

• Removing the insert tang after installation when the repair process requires a clear through path
• Completing insert assembly in maintenance and production repair work without damaging the repaired thread
• Using a dedicated finishing tool instead of improvised impact methods on the insert tang
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: thread cutting, re tapping, and thread cleaning depending on condition

Note Select the product by thread designation, workpiece condition and the holder concept used in your process.

• Matched repair logic supports repeatable restoration of an existing thread designation
• Insert based repair can improve service life of the receiving thread in repeated assembly work
• Suitable for maintenance, overhaul and workshop repairs where part replacement is undesirable
• Clear assignment between preparation, tapping and insert installation reduces handling errors

• The process depends on the correct repair sequence and is not suitable when the parent material is cracked or too thin for the repair concept.
• It is a repair system and not the fastest choice when you only need a one time emergency fix without the full preparation steps.

1. Confirm that the insert is seated correctly in the repaired thread before finishing.
2. Position the tang break tool centrally over the insert tang.
3. Apply the removal action in a controlled manner without striking the thread flank area.
4. Remove the released tang from the hole so the thread path stays clear.
5. Check the thread entry for burrs or loose fragments.
6. Clean the tool and store it protected from impact damage.

What do you use Tang Break Tool No. 13 for?

You use this product when an internal thread must be restored, reinforced or prepared within a wire thread insert repair process. The exact role depends on whether the product is the kit, the insert, the STI tool or the installation accessory.

What is STI in this repair context?

STI refers to the receiving thread used for wire thread inserts, so the preparation tool must match the insert system rather than a normal direct fastening thread.

What should you check before assembly after repair?

Check that the repaired thread is clean, the insert sits correctly when applicable and the mating fastener engages smoothly without cross threading.
