Heli-coil 17551-2-5 Thread Insert Tool Replacement Blades

Product Description

The HELI-COIL 17551-2-5 is a set of replacement blades for the HELI-COIL hand installation tool used with tangless thread inserts in 8-32 UNC threaded applications. These blades are the wear component of the hand tool driver and are replaced when the existing blades become damaged or worn, keeping the installation tool functional without replacing the entire driver assembly. Designed for use with tangless insert systems, the blades engage the insert and drive it into a prepared hole to the correct depth. Machinists, maintenance technicians, and assembly professionals working with HELI-COIL tangless inserts will find these a necessary consumable item for sustained tool performance.

These replacement blades are suited for repair and assembly operations where 8-32 UNC tangless thread inserts are installed by hand. Typical applications include thread repair on aluminum, steel, and cast components in manufacturing, MRO, and field service environments. They are used wherever a hand installation tool is preferred over a power driver, particularly in confined spaces or on delicate assemblies where torque control is critical.

Installation Notes

Installation of thread inserts and tool blade replacement is typically performed by machinists, assembly technicians, or MRO maintenance personnel. Before replacing blades, ensure the tool is not under load and that the work area is clear. Follow the tool manufacturer's disassembly procedure when swapping blades to avoid damage to the driver body. Do not use a damaged or improperly seated blade, as it may misalign the insert during installation.
