Heli-coil 17552-3-5 Insert Tool Replacement Blades 10-32 Unf

Product Description

The HELI-COIL 17552-3-5 is a replacement blade set for hand installation tools used to install tangless thread inserts in 10-32 UNF threaded applications. The blades are the contact component that engages the insert during installation, and they wear over time with repeated use. Replacing worn blades restores proper engagement geometry and reduces the risk of misinstalled or cross-threaded inserts. This part is sized specifically for 10-32 UNF thread inserts and is intended for use by assembly technicians, maintenance mechanics, and field service professionals who rely on hand installation tooling for thread repair or reinforcement work.

These replacement blades are used in hand installation tool assemblies for tangless thread inserts in 10-32 UNF applications. Tangless inserts are common in aerospace, defense, and precision industrial assembly where removal of the installation tang is not practical or permitted. The blades fit into the corresponding HELI-COIL hand tool body and are swapped out as a service item to maintain consistent installation performance across high-volume or recurring thread insert operations.

Installation Notes

Blade replacement should be performed by a qualified assembly technician familiar with thread insert tooling. Before replacing blades, ensure the tool is not under load and that no insert is engaged in the blade slot. Follow the tool manufacturer's disassembly procedure for the specific hand tool body in use. Improper blade seating can result in insert damage or failed installations.
