How do you select the correct tang break tool?
Match the tool execution to the insert size range and drive interface stated in the product name. Use stable alignment and avoid contact with the insert coil body.

When do you remove the tang?
Remove the tang after the insert is installed to depth and before final assembly, when a clear bore is required for functional use.

How do you avoid damaging the installed insert?
Keep the tool centred, apply a controlled drive action, and remove loose debris before and after tang removal. Avoid side load that can deform coils.

Can you use the tool for blind and through holes?
Depending on access, you can use the tool where it can be guided straight to the tang. Ensure the tang can be removed from the bore so it does not remain loose in the part.

How do you verify the repair after tang removal?
Check that the tang is fully removed and the bore is clear, then verify assembly with the intended fastener or inspection method suitable for the application.

What practical limitations apply to thread repair tools?
Results depend on correct preparation steps, cleanliness, and insert system execution. Validate the process when loads are critical.
