Heli-coil 7572-3-5 Thread Insert Tool Replacement Blades 10-32

Product Description

The HELI-COIL 7572-3-5 is a set of replacement blades for the HELI-COIL hand installation tool used with tangless thread inserts. These blades are the working contact component inside the hand tool, engaging the insert during installation to drive it into a prepared tapped hole. Designed for 10-32 UNF thread size, they are a direct service part that restores a worn or damaged installation tool to full working condition. Maintenance technicians, aerospace assemblers, and general-purpose machinists who rely on HELI-COIL tangless insert systems for thread repair and reinforcement will use these replacement blades as part of routine tooling upkeep.

These replacement blades are suited for use in any application where tangless HELI-COIL thread inserts are installed by hand at the 10-32 UNF thread size. Typical environments include production assembly, MRO facilities, and field repair work on aluminum, steel, or composite components where thread repair or thread reinforcement is required. Because tangless inserts do not require a separate tang break-off step after installation, the blade geometry is specific to the tangless insert design and is not interchangeable with standard tanged insert tooling.

Installation Notes

Blade replacement should be performed by a mechanic or assembler familiar with HELI-COIL hand installation tool disassembly. Ensure the tool is fully unloaded and no insert is engaged before removing or installing blades. Refer to the HELI-COIL tool service documentation for proper blade seating procedure. Incorrect blade installation can result in damaged inserts or improper insert placement.
