Heat-Set Insert Tips M2 to M8, 8 Pieces

★★★★★ 4.6 out of 5 · 66 ratings

Metal threads in a plastic print, done right: seven brass tips from M2 to M8 and a long adapter that screws onto a standard soldering iron. The extended tip heats the insert without touching the wall of the part, so the brass sinks in straight and the print keeps its shape.

7 brass tips: M2, M2.5, M3, M4, M5, M6, M8, plus one soldering-iron adapter
Brass for fast, even heat and long life
Long reach keeps the hot shaft off the part
Tight adapter thread, no wobble under pressure

Questions about this kit

Does it fit my soldering iron?

The adapter screws onto irons with a threaded tip holder; check that yours accepts a screw-in tip before ordering.

What temperature do I set?

About 200 to 220 degrees Celsius for PLA and PETG, 240 for ABS; let the weight of the iron sink the insert.
