Helicoil Tang Break Off Tool

Heli-Coil Tang Break-Off Tools

The driving tangs of Heli-Coil inserts must be removed to eliminate their interference with the end of the assembled bolt. Heli-Coil tang break-off tools are available for use with inserts through 1/2 inch and 12mm metric nominal diameter. Their operation is automatic, having a spring loaded, easily triggered punch that strikes a sharp, uniform blow against the tang of the installed insert. The tool can be operated with one hand.

Heli-Coil Extracting Tools

Occasionally Heli-Coil inserts must be removed. Inserts may be removed manually with little effort. This is done by inserting the blade of the extracting tool into the Heli- Coil insert so that the V section of the blade is toward the top end of the insert. Strike the head of the tool with a light blow. Maintaining a steady pressure of blade against insert, turn the extracting tool counterclockwise until the insert is removed.
