RUTHEX SOLDERING TIPS FOR RUTHEX THREAD INSERTS: The ruthex soldering tips make it even easier to retrofit thread inserts into 3D printed parts of 3D printers from e.g. Anycubic or Prusa.
PRACTICAL CHANGE SYSTEM: Due to the thread in the soldering iron adapter, the soldering tips can be changed very easily WITHOUT completely unscrewing the soldering iron.
INSERTION HELP COMPATIBLE for soldering iron heads 900M and T18 for example for soldering stations SREMTCH, Hakko, LONOVO, RHAEGON, WaxRhyed and other brands. Dimensions of the soldering iron adapter can be taken from the drawing.
NO DAMAGE TO 3D PRINTING PART: Due to the ideal geometry of the soldering tips, the 3D printing parts will not be damaged. Common damage without ruthex soldering tips is, for example, damage to the surface around the thread insert.
PRACTICAL THREAD INSERT SET: The ruthex soldering iron tip set includes tips for M2 / M2.5 / M3 / M4 / M5 / M6 / M8 thread inserts and a soldering iron adapter. The ideal temperature for insertion is 10-15 degrees above the hotend temperature of the 3D printing filament.
