FFVRVSS Heat Set Insert Tool Tips M2-M8 | Precision Brass Construction for 3D Printing

• EFFORTLESS HEAT-SET INSERT INSTALLATION — Stop melting 3D prints with standard soldering tips. Our 7 brass tips (M2, M2.5, M3, M4, M5, M6, M8) seat threaded inserts cleanly into PLA, PETG, ABS, ASA—no ruined prints, just strong reusable threads.
• PRECISION-MACHINED BRASS CONSTRUCTION — Each tip is CNC-machined from high-conductivity brass for a perfect dimensional fit. The slim-neck design reaches deep into recesses without touching adjacent walls, preventing surface melting on your prints.
• BUILT FOR MAKERS AND 3D PRINTING — Turn brittle printed threads into durable metal connections for drone frames, enclosures, and prototypes. For hobbyists and engineers who assemble and disassemble parts repeatedly without stripping.
• QUICK-CHANGE THREADED SYSTEM — Unlike one-piece tips requiring full iron disassembly, our split threaded design swaps sizes in seconds—no tools needed. Compatible with 900M/T18 heads: Hakko FX-888D, FX-600, Weller WLC100, SP40NUS, Yihua and more.
• PREMIUM VALUE KIT WITH STORAGE — Includes 7 tips (M2-M8), 900M/T18 adapter, and a clear storage case to keep your workbench organized. FFVRVSS quality at a price that makes upgrading from a bare soldering iron tip an easy decision.

• Select the Correct Tip and Insert — Choose the FFVRVSS brass tip that matches your desired threaded insert size (e.g., M4 tip for M4 insert). Ensure your soldering iron is compatible with the 900M/T18 adapter and is heated to the appropriate temperature for your plastic filament.
• Attach Tip to Soldering Iron — Carefully screw the selected brass tip onto the FFVRVSS adapter, then screw the adapter onto your heated soldering iron. Ensure a snug fit to allow for efficient heat transfer during the insertion process.
• Insert Threaded Fitting — Align the threaded insert with the pre-drilled hole in your 3D print. Gently press the heated tip onto the insert, allowing the brass to melt the plastic around the insert. Maintain steady pressure until the insert is fully seated and flush with the surface.
• Remove Iron and Allow Cooling — Once the insert is seated, carefully remove the soldering iron. Allow the plastic and insert to cool completely before handling or attempting to screw in a bolt. Clean the tip after use for longevity.
