Heli-coil 17551-06-5 Replacement Blades 6-32 Unc

Product Description

The HELI-COIL 17551-06-5 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 of the hand tool, engaging the insert during the driving process to seat it flush within a tapped hole. Designed for 6-32 UNC thread size, the blades are a direct service part that restores tool function when worn or damaged blades reduce installation performance. Installation technicians in HVAC, electrical, mechanical assembly, and general maintenance applications rely on this type of tooling to install thread inserts cleanly and consistently without damaging the parent material.

These replacement blades are suited for use in any environment where HELI-COIL Tangless inserts are installed by hand in 6-32 UNC tapped holes. Typical applications include light equipment assembly, control panel fabrication, field repair of stripped threads in metal housings, and maintenance work where power tooling is not appropriate or available. The hand installation method gives technicians direct tactile feedback during seating, making this tooling well suited to delicate or close-tolerance work.

Installation Notes

Blade replacement should be performed by a mechanic or technician familiar with HELI-COIL tooling. Power down or de-energize any equipment before performing thread insert work in or near electrical components. Inspect the tool body for wear or damage before installing new blades to confirm the replacement blades will seat and function correctly. Follow the tool manufacturer's assembly instructions when fitting replacement blades to avoid misalignment during insert driving.
