✓【INTEGRATED ONE-PIECE DESIGN】No adapter needed. Each tip screws directly onto 900M/T18 iron heads for maximum heat transfer. 6 sizes (M2, M2.5, M3, M4, M5, M6) seat threaded inserts cleanly into PLA, PETG, ABS, ASA—no ruined prints, strong threads.
✓【SUPERIOR HEAT CONDUCTIVITY】Unlike two-piece tip-plus-adapter setups that lose heat at the junction, our integrated solid-brass tips deliver faster heat-up and consistent insert seating. Less waiting, fewer crooked inserts, stronger metal threads.
✓【PRECISION-MACHINED BRASS】Each tip is CNC-machined from high-conductivity brass for a perfect fit with M2-M6 inserts. The slim-neck design reaches deep into recesses without touching adjacent walls, preventing surface melting on your printed parts.
✓【QUICK-CHANGE THREADED SYSTEM】Swap between M2, M2.5, M3, M4, M5, and M6 in seconds—just unscrew and replace, no tools needed. Compatible with Hakko FX-888D, FX-600, Weller WLC100, SP40NUS, Yihua 939D, 926, and any 900M or T18 style soldering iron.
✓【PREMIUM VALUE KIT WITH STORAGE】Includes 6 integrated brass tips (M2, M2.5, M3, M4, M5, M6) and a premium clear storage case to keep your workbench organized. FFVRVSS quality makes upgrading from a bare soldering iron tip an effortless decision.
