Heli-coil 7571-3-3B Mandrel 10-24 Unc Thread Insert Tool

Product Description

The HELI-COIL 7571-3-3B is a mandrel-type power installation tool designed for driving threaded wire inserts into pre-tapped holes. It accepts 10-24 UNC thread inserts and is built for use with power drive equipment, allowing faster and more consistent insert installation compared to hand tools. The mandrel engages the insert tang during installation and is compatible with both bulk inserts and strip feed inserts, making it a versatile option for shops and field technicians running high-volume thread repair or thread reinforcement work. The tool weighs 0.44 pounds.

This mandrel tool is suited for applications in manufacturing, MRO, and field repair environments where 10-24 UNC Heli-Coil inserts are used to create or restore durable threaded fastening points in softer base materials such as aluminum, magnesium, and plastic. It is appropriate for both production-line assembly and repair scenarios where power installation is preferred over hand installation for speed and repeatability.

Installation Notes

Installation should be performed by a machinist, assembler, or qualified technician familiar with threaded insert systems. Ensure the base material hole is tapped to the correct Heli-Coil tap size for 10-24 UNC before driving the insert. Secure the workpiece before operating the power tool to prevent movement during installation. Follow the tool manufacturer's torque and speed guidelines for the power drive equipment being used.
