HeliCoil Tang Break Off Tools

The manual HeliCoil Tang Break Off Tool is included in HeliCoil thread repair kits and is extremely 
simple to use. After installation of the HeliCoil screw thread insert, place the manual tang breaker 
squarely on the tang and give a sharp strike with a hammer. 

Recommended for use in high volume production, the HeliCoil Automatic Tang Break Off Tool 
features a spring loaded, easily triggered punch. When activated, the punch strikes a sharp, uniform 
blow against the tang of the installed HeliCoil wire thread insert, breaking it off cleanly.

The driving tangs of HeliCoil inserts must be removed to eliminate their interference with the end of the assembled bolt. Emhart 
Technologies HeliCoil Tang Break Off Tools are available for use with inserts up to 1/2 and M12 nominal diameter. For sizes larger than 
these, use long nosed pliers to remove the tang from the HeliCoil Insert. Bend the tang up and down to snap it off at the insert notch.
