V-COIL Inserting Tool No. 21

• installing V-COIL wire thread inserts after the receiving thread has been prepared
• repair work where insert seating position must be controlled by the correct inserting tool
• replacement or supplementary tool use in existing V-COIL repair workflows
• selection by tool number or thread designation No. 21

Note The inserting tool installs the insert only; drilling, STI tapping, and cleaning must be completed with the matching repair tools.

• dedicated V-COIL tool function supports controlled insert placement
• selection by No. 21 reduces the risk of using a tool from a different repair size
• separate tool supply helps replace a worn or missing installation tool without replacing a complete kit
• tool-only format is useful when inserts and preparation tools are already available

• The tool does not include inserts or preparation tools; use a complete V-COIL repair kit when the full repair sequence is not available.

1. Confirm that the prepared thread and insert match the inserting tool size.
2. Clean the prepared thread before placing the insert on the tool.
3. Place the wire thread insert on the inserting tool according to the repair process.
4. Drive the insert into the receiving thread with steady axial alignment.
5. Stop when the insert reaches the required seating position.
6. Remove the inserting tool without pulling the insert out of position.
7. Finish the repair by removing the tang where the insert type requires that step.
