Hakko T18-B Conical Solder Tip, 0.50Mm
Hakko T18-B — Conical Solder Tip, 0.50mm
The Hakko T18-B is a 0.50mm conical solder tip for the Hakko FX-888D, FX-888, and legacy 900M/936/937 series soldering stations. The conical point profile tapers to a fine tip, providing maximum access precision for SMD rework, touch-up on individual leads, bridging removal, fine wire tacking, and any application requiring access to a single pad or lead in a densely populated board area. The 0.50mm point is one of the most precise tips in the standard T18 lineup.

Soldering Tip Care Guide
- Tin before and after every use — fine conical tips are highly vulnerable to oxidation; always maintain a solder coat on the point.
- Use brass wire tip cleaner with care — plunge gently into brass wool (Hakko 599B-02) to avoid bending or deforming the fine conical point. Avoid wet sponges where possible.
- Re-tin immediately after cleaning — the fine point oxidizes rapidly when bare at operating temperature.
- Use tip tinner/activator on oxidized tips — if the tip dewets, apply tip tinner promptly to restore the tinned surface before the condition progresses.
- Keep temperature as low as practical — conical tips are more sensitive to oxidation at high idle temperatures; use the lowest effective setpoint for your solder alloy.
- Replace tips showing deformation, pitting, or persistent dewetting — a bent or oxidized conical tip cannot deliver precise joints and should be replaced promptly.
Frequently Asked Questions
What is a conical tip best used for?
Conical tips taper to a fine point, making them ideal for precision access in tight spaces — SMD rework and touch-up on individual leads, solder bridge removal, fine wire tacking, jumper wire attachment, and any application where other tip shapes would risk contacting adjacent components or pads. The tradeoff is lower thermal efficiency compared to chisel or bevel tips; conical tips transfer less heat per contact due to the small contact area, so they are best suited for low-mass joints and precision work rather than production volume soldering.
What stations is the Hakko T18-B compatible with?
The T18-B 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 does the T18-B differ from the T18-BL and T18-I?
The T18-B is a standard-length conical tip at 0.50mm. The T18-BL is a long conical tip at 0.20mm — finer point and extended reach for even tighter access. The T18-I is an ultra-fine conical at 0.20mm standard length. Choose the T18-B for general precision rework; choose the BL or I when you need an even finer point or extended reach into recessed areas.
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.
