Heli-Coil Thread Repair Insert Installation Mandrel

The Heli-Coil Thread Repair Insert Installation Mandrel is a hand tool for installing Heli-Coil wire thread repair inserts, also called helical coil inserts or thread repair inserts. It is used to restore stripped, damaged or worn internal threads. It is also used to create strong, wear-resistant threads in softer base materials.

Key Features:

• Designed to install Heli-Coil thread repair inserts into a prepared, tapped hole
• Engages the driving tang of the insert so it can be threaded into place in the hole
• Works with the matching Heli-Coil insert size and thread pitch for each mandrel
• Hand-operated tool that suits shop, garage and field repairs
• Part of the Heli-Coil thread repair system, a long-established name in thread repair

Use the mandrel with the correct Heli-Coil tap and inserts to bring a damaged thread back to a usable condition. Choose the variant that matches the thread size and pitch of the insert you are installing.
