Hakko T18-C4 Beveled Solder Tip, 4.00Mm
Hakko T18-C4 — Bevel Solder Tip, 4.00mm
The Hakko T18-C4 is a 4.00mm bevel (C-type) solder tip for the Hakko FX-888D, FX-888, and legacy 900M/936/937 series soldering stations. The T18-C4 is the widest bevel in the standard T18 C-series, providing maximum contact area for aggressive heat delivery to the highest-mass joints in the T18 lineup. It is best suited for power terminal soldering, large through-hole connector pins, heavy wire terminations, bus bars, and any application where a smaller tip loses temperature rapidly on contact and struggles to bring the joint to reflow temperature.

Soldering Tip Care Guide
- Tin before and after every use — coat the tip with fresh solder before setting the iron down and at session end to prevent oxidation.
- Use brass wire tip cleaner — plunge the tip into brass wool (Hakko 599B-02) to remove flux residue without thermal shock. Avoid wet sponges where possible.
- Re-tin immediately after cleaning — never leave a bare tip exposed at temperature; oxidation begins within seconds.
- Use tip tinner/activator on oxidized tips — if the tip dewets (solder beads off), apply tip tinner compound to restore the tinned surface.
- Keep temperature as low as practical — lower idle temperatures slow oxidation and extend tip life significantly.
- Replace tips showing cracks, pitting, or persistent dewetting — a damaged tip transfers heat poorly and produces unreliable joints.
Frequently Asked Questions
How does the T18-C4 compare to other bevel sizes in the T18 series?
The T18-C4 at 4.00mm is the widest bevel in the standard T18 C-series and is best reserved for the highest-mass joints where smaller tips struggle to maintain reflow temperature on contact. For large but less demanding joints, the T18-C3 (3.00mm) is often sufficient. For general-purpose and mixed-assembly work, the T18-C2 (2.00mm) is the most versatile choice. For fine SMD and tight-pitch work, use the T18-C1 (1.00mm) or T18-C08 (0.80mm).
What stations is the Hakko T18-C4 compatible with?
The T18-C4 is compatible with the Hakko FX-888D, FX-888, 936, 936-ESD, 937, 928, 913, 907, 907-ESD, 900M, 900M-ESD, and 703 soldering stations and irons. It is not compatible with the FX-951 (T15 series) or FX-971/FX-972 (T39 series).
What is a bevel (C-type) tip and when should I use one?
A bevel tip (C-type) has an angled, concave face that holds a small solder pool for controlled delivery. It provides more surface contact than a conical tip while remaining more precise than a chisel, making it versatile across SMD, through-hole, and connector work. At 4.00mm, the C4 is optimized for heat-demanding applications rather than precision fine-pitch work.
How do T18 tips differ from T15 and T39 series tips?
T18 tips are designed for the FX-888D/FX-888 and legacy 900M/936 series stations. T15 tips are for the now-discontinued FX-951 station. T39 tips are for the current FX-971 and FX-972 stations. The three series are not interchangeable — always match the tip series to your specific station model.
