V-COIL Inserting Tool (Drive connector 1/2") UNF 1.3/8

• Mounting the wire insert securely before you guide it into the prepared receiving thread
• Keeping the insert aligned during installation so the first coil enters without skewing
• Using a matching drive concept when you install inserts in workshop or machine assisted repair work
• 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. Inspect the tool and the insert so the driving feature is clean and undamaged before mounting.
2. Place the insert onto the tool and confirm secure engagement of the drive point.
3. Align the prepared receiving thread and bring the tool to the entry without tilting.
4. Drive the insert into the thread with steady feed while maintaining alignment.
5. Stop the installation when the insert reaches the intended seated position.
6. Back the tool out carefully, then clean and protect the tool before storage.
