• FAST AND CONTROLLED HEATING: The 90W ceramic heating core heats quickly and provides responsive temperature control. The digital LED display, plus and minus buttons, °C/°F switching and automatic sleep function make it easier to adjust the iron for different insert sizes and plastic materials.
• STRAIGHTER, CLEANER INSTALLATION: Seven flat-ended heat-set tips transfer heat directly to the brass insert and help keep it aligned while pressing it into the pilot hole. The threaded quick-change design allows you to switch between M2, M2.5, M3, M4, M5, M6 and M8 tips.
• FOR 3D PRINTING AND PLASTIC REPAIRS: The brass inserts feature knurled outer surfaces that grip the surrounding plastic after cooling, creating durable internal threads for repeated assembly. Suitable for compatible thermoplastic enclosures, jigs, fixtures, electronics housings, models and hobby projects.
