Heli-coil 18552-3-30 Unf Mandrel Thread Insert Tool 10-32

Product Description

The HELI-COIL 18552-3-30 is a mandrel-type power installation tool designed to drive threaded wire inserts into pre-tapped holes quickly and consistently. It is built for use with 10-32 UNF thread inserts and is compatible with both bulk inserts and strip feed inserts, making it a flexible option for production environments and field repair work. The mandrel engages the installation tang of the insert and winds it into the receiving thread under power, reducing hand fatigue compared to manual drivers. Installers working in aerospace, automotive, electronics, and general mechanical repair rely on this type of tool when insert volume or access conditions make hand installation impractical.

This tool is suited for applications where 10-32 UNF threaded holes require reinforcement or repair in parent materials such as aluminum, magnesium, or other soft metals. It is commonly used in production-line assembly, MRO shops, and field service settings where consistent insert depth and torque control are priorities. The dual compatibility with bulk and strip feed inserts gives the technician flexibility across different insert supply formats without switching tools.

Key Features

• Designed for 10-32 UNF thread size inserts for precise fitment
• Mandrel-type power installation eliminates manual winding effort
• Compatible with both bulk inserts and strip feed inserts
• Suited for production and field repair environments
• Lightweight at 0.25 pounds for reduced operator fatigue during extended use

Compatibility

Designed for use with HELI-COIL 10-32 UNF threaded wire inserts in both bulk and strip feed formats. Specific insert part number compatibility should be confirmed against HELI-COIL tooling charts prior to use.

Installation Notes

A licensed mechanic, MRO technician, or assembly professional should install this tool in accordance with the insert manufacturer's procedures. Ensure the parent material hole is tapped to the correct HELI-COIL STI tap specification before driving inserts. Verify that the power tool drive speed is set within the range recommended for the insert size to avoid cross-threading or overtorque. Remove the installation tang after insert seating using the appropriate tang break-off tool where required by the application.
