This is for a New HeliCoil Prewinder 55071 for M7 x 1.0 Thread Size.

PLEASE NOTE: Each bid is for 1 tool.

Prewinders are used to compress the diameter of a coil insert before being installed into a threaded hole.

Installation tools for helical inserts help users install threaded inserts to ensure a secure connection between the mounting surface and the insert. They grip the inserts while installing them and break the installation tang free inside tanged inserts, ensuring the correct fit.
