Hakko T18-D24 Chisel Solder Tip, 2.40Mm
Hakko T18-D24 — Chisel Solder Tip, 2.40mm
The Hakko T18-D24 is a 2.40mm chisel solder tip for the Hakko FX-888D, FX-888, and legacy 900M/936/937 series soldering stations. The 2.40mm chisel width is a popular general-purpose size, providing a larger contact surface for efficient heat transfer to standard through-hole pads, larger SMD pads, wire terminations, and connector pins. The flat chisel profile allows simultaneous contact with pad and lead for fast, consistent joints.

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
What stations is the Hakko T18-D24 compatible with?
The T18-D24 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).
When should I use a 2.40mm chisel tip vs. a smaller or larger chisel?
The T18-D24’s 2.40mm width is a versatile general-purpose size ideal for standard through-hole component leads, medium-size SMD pads, wire terminations, and connector pins. For tighter spaces or fine-pitch SMD work, choose the T18-D16 (1.60mm) or T18-D08 (0.80mm). For heavy-mass joints, larger pads, or drag soldering wide lead arrays, consider the T18-D32 (3.20mm).
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.
Is the Hakko FX-888D still the right station for T18 tips?
Yes — the FX-888D is a current-production Hakko station and the primary station for T18-series tips. If you are purchasing a new station, the FX-888D remains the standard recommendation for T18 tip users. The FX-971 and FX-972 use T39-series tips and represent a separate, newer product line.
