Product Information
Full details
The Duratool 5mm Knife Soldering Iron Tip (N9-5) is designed for electronics hobbyists and professionals who rely on the ZD-8936 48W temperature-controlled soldering station. Its distinct knife-edge profile provides excellent heat transfer and versatility, making it perfect for drag soldering and handling surface-mount components, though users should note it is exclusively compatible with specific ZD-series models and requires careful thermal management during use.

FAQs
Is this tip compatible with other soldering stations?
No, this tip is specifically designed for the ZD-8936 (D03168) soldering station.
How wide is the soldering edge?
The tip features a 5mm knife-style edge.
Can I use this for lead-free solder?
Yes, it is compatible with both leaded and lead-free solder.
How often should I replace the tip?
Replacement frequency depends on usage intensity, but if you notice the tip pitting or failing to hold solder even after cleaning, it is time for a new one.
What is the best way to clean this tip?
Use brass wool or a dedicated tip tinner/cleaner. Avoid using files or sandpaper, which will destroy the protective plating.
Troubleshooting
Tip fails to heat up
Ensure the tip is fully seated in the heating element barrel and the retaining nut is tightened correctly.
Solder will not stick to the tip
The tip may be oxidized. Clean it with brass wool and apply fresh leaded or lead-free solder immediately while the iron is hot to re-tin the surface.
Pros and Cons
Pros
- Excellent for drag soldering techniques
- Precise knife shape allows for tight-space access
- High-quality construction for consistent performance
- Tailored specifically for ZD-8936 compatibility
Cons
- Not compatible with universal soldering handles
- Requires proper tinning to prevent oxidation
- Larger profile may be less ideal for microscopic work
Setup, Compatibility & Care
To install, ensure the soldering station is completely powered off and the iron handle has reached room temperature. Loosen the sleeve or barrel nut on your ZD-8936 handle, slide out the existing tip, and insert the N9-5 tip carefully. Secure the nut firmly without overtightening. To ensure longevity, always keep the tip tinned with a thin layer of solder before powering down. Avoid using abrasive materials to clean the tip, as this can strip the plating; instead, use a brass wool cleaner or a damp cellulose sponge to remove oxidized residue during operation.
