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" 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.
Occasionally Heli-Coil inserts must be removed. With the Heli-Coil removal tool, inserts can be removed manually with little effort.
