Hakko T18-S9 Chisel Solder Tip, 1.20Mm
Hakko T18-S9 — Chisel Solder Tip, 1.20mm
The Hakko T18-S9 is a 1.20mm chisel solder tip for the Hakko FX-888D, FX-888, and legacy 900M/936/937 series soldering stations. The S9 presents a flat chisel working face at 1.20mm width, suited for SMD pad soldering, small through-hole leads, moderate-pitch component work, and general-purpose bench soldering where a fine-to-mid chisel profile is preferred. At 1.20mm it is closely comparable to the T18-D12 standard chisel, offering an S-type face geometry as an alternative for operators with a preference for this profile.

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, 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-S9 compare to the T18-D12?
Both the T18-S9 and T18-D12 are 1.20mm chisel tips for the same compatible stations. The difference is in face geometry — the D12 is a standard D-type chisel with a squared flat face, while the S9 is an S-type chisel with a slightly different face profile. For most applications they are functionally interchangeable at the same width; tip style preference is typically operator-driven. If you already use D-type chisels across your workflow, the D12 is the consistent choice. If your team prefers S-type geometry, the S9 delivers the same 1.20mm working width.
What stations is the Hakko T18-S9 compatible with?
The T18-S9 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).
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.
