Hakko T18-S7 Beveled Solder Tip, 1.20Mm
Hakko T18-S7 — Bevel Solder Tip, 1.20mm
The Hakko T18-S7 is a 1.20mm bevel solder tip for the Hakko FX-888D, FX-888, and legacy 900M/936/937 series soldering stations. The S-type bevel profile provides a flat angled working surface for SMD pad soldering, through-hole lead work, and general-purpose PCB assembly. At 1.20mm, the T18-S7 is closely sized to the T18-D12 chisel and T18-S6 bevel, offering a fine-to-mid bevel option for operators who prefer the S-type face geometry for their work style and component pitch.

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-S7 compare to the T18-S6 and other nearby sizes?
The T18-S7 at 1.20mm is slightly narrower than the T18-S6 (1.30mm) and closely comparable to the T18-D12 chisel (1.20mm). The S7 and S6 differ in face width by 0.10mm — for most applications they are interchangeable, with the S7 offering marginally more precision in tighter pad geometries. For finer work, step down to the T18-C1 (1.00mm) or T18-C08 (0.80mm). For larger pads, step up to the T18-C2 (2.00mm) or T18-S6 (1.30mm).
What stations is the Hakko T18-S7 compatible with?
The T18-S7 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.
