Guide for Threaded Insert Soldering Iron (16–19mm)

Perfectly straight heat-set inserts every time – simple, fast and effective tool.

This self-leveling guide helps you melt threaded inserts cleanly, straight, and precisely with a soldering iron. Thanks to the integrated spirit levels, you can ensure that the insert sits exactly vertically without tilting or jamming.

The tool is simply placed on the soldering iron and simultaneously serves as a stable guide and visual control during melting. This makes the work significantly easier, more reproducible, and more professional.

Ideal for use with 3D printed parts (e.g., PETG, PLA, ABS, ASA, etc.).

Advantages:

• Precise, straight melting of threaded inserts
• Integrated spirit levels for perfect alignment
• Easy assembly – simply slide onto the soldering iron
• Improves stability and control during work
• Very fast printing and low material consumption
• Light, compact, and effective

Available variants (inner diameter):

• 16 mm
• 17 mm
• 18 mm
• 19 mm

Choose the variant matching your soldering iron.
