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..

Note: Tang break-off tools will break- off tangs thru 2 diameter lengths. For sizes larger than 1/2" or 12mm, use long nose pliers. Bend tang up and down to snap off at notch.
