What Is the Uxcell 3.4x67mm Soldering Iron Tip?
The uxcell 3.4x67mm Lead-free Soldering Iron Tip Replacement is a conical replacement tip for soldering irons that accept a 3.4 mm shank. It is not a full soldering iron, and it will not solve problems caused by a weak heating element, damaged cord, or incompatible station.
The tip uses an alloy construction mainly made with copper, iron, nickel, chromium, and tin. That material mix supports heat transfer, solder wetting, and oxidation resistance when you keep the tip clean and properly tinned.
Before You Buy: Measure your current soldering iron tip before ordering. This replacement is made for a 3.4 mm shank and 30W fit, so it may not work with irons that use larger, smaller, threaded, cartridge, or station-specific tips.
Features and Specifications
The main appeal of this uxcell tip is its simple, practical design. Its 67 mm total length and 3.4 mm shank make it a focused replacement part for compatible 30W soldering irons, especially when your existing tip has become oxidized, pitted, or slow to wet with solder.
The conical shape gives you a narrow contact point for small solder joints. That shape can help when you work on wires, small connectors, circuit board pads, hobby electronics, or other tasks where a wide chisel tip would feel too bulky.
The lead-free material design also matters if you use modern lead-free solder. Lead-free solder usually needs clean heat transfer and good tip care, so you will get better results when you tin the tip often and avoid running the iron dry for long periods.
Who Should Buy It?
Best For
- You have a compatible 30W soldering iron that uses a 3.4 mm shank tip.
- You need a fine conical point for small electronics, wires, and hobby repairs.
- You want a low-cost replacement before buying a new soldering iron.
Skip If
- Your soldering iron uses cartridge-style, threaded, or station-specific tips.
- You need a wide chisel tip for larger joints, terminals, or heavy heat transfer.
- Your iron has heating problems that a new tip cannot fix.
Design and Build Quality
This uxcell tip uses an alloy build instead of a plain soft-metal design. The listed material mix, including copper, iron, nickel, chromium, and tin, gives the tip a balance of heat transfer, surface durability, and solder-wetting ability.
For buyers, that means the tip should heat quickly on a compatible iron and hold solder better than a badly oxidized old tip. Still, every soldering tip is a wear item. Heat, flux residue, dry wiping, and poor storage can shorten its life.
Heat Transfer and Soldering Performance
With a compatible 30W iron, this tip is meant to support fast heating and steady contact with small solder joints. The conical point can place heat where you need it without covering nearby parts.
That focused shape works well for light-duty jobs. It is less ideal for large wire lugs, heavy terminals, or metal parts that pull heat away quickly. For those jobs, a chisel or bevel tip usually gives more surface contact.
Compatibility and Fit
Compatibility is the most important detail with this replacement tip. The shank diameter is 3.4 mm, so your soldering iron must accept that size for the tip to seat correctly and transfer heat properly.
Do not rely on wattage alone. A 30W soldering iron can still use a different tip system, so check the diameter, tip length, and fitting style against your existing tip before you order.
Pro Tip: Remove your old tip only after the iron is unplugged and fully cool, then measure the shank with calipers if possible. A small size mismatch can cause poor heat transfer or a loose fit.
Lead-Free Soldering Use
This tip is designed for lead-free soldering tasks, which is useful for modern electronics work. Lead-free solder can be less forgiving than leaded solder because it often needs a clean, well-tinned surface and steady heat.
To get better results, keep a thin layer of solder on the tip when the iron is hot. This helps protect the surface from oxidation and makes it easier for solder to flow onto the joint.
Compatibility and Soldering Safety
Before you install or clean any soldering tip, unplug the iron and let it cool fully. A soldering tip can hold enough heat to burn skin or damage nearby surfaces even after the iron is turned off.
Use eye protection, work in a ventilated area, and follow your soldering iron’s instructions. Flux fumes, hot solder, and exposed electrical parts can create risks if you rush the job or work without a stable surface.
How It Performs in Real Use
For Small Electronics Repair
The conical point is useful when you need to touch small pads, wires, or connectors without flooding the area with too much solder. It gives you better control than a broad tip when the joint is small.
For Hobby and DIY Projects
For basic kits, wire repairs, LED projects, and small household electronics work, this tip gives you a practical replacement if your existing tip no longer wets properly. Its value is strongest when your iron already works well.
For Lead-Free Solder
The lead-free design supports modern soldering materials, but technique still matters. Let the tip reach working temperature, tin it before use, and clean it gently with a brass sponge or damp sponge.
For Long-Term Use
Long-term performance depends on care. Avoid scraping the tip with a knife or sandpaper, because that can damage the plated surface and make oxidation worse over time.
How to Use It Correctly
- Unplug your soldering iron and let it cool fully before removing the old tip.
- Compare the old tip with the 3.4 mm shank size and 67 mm total length.
- Install the new tip firmly, but do not force it into an incompatible iron.
- Heat the iron and apply a small amount of solder to tin the tip before your first joint.
- Clean the tip during use with a brass sponge or damp sponge, then re-tin it before storage.
Cleaning and Maintenance
Good maintenance is the difference between a tip that works smoothly and one that turns black, dry, and difficult to use. Wipe the tip during soldering, not after it has been left dirty for a long time.
When you finish, add a small amount of solder to the hot tip before turning off the iron. That protective layer helps reduce oxidation while the tip cools.

Is It Worth the Price?
The uxcell 3.4x67mm soldering iron tip is worth considering if you want a simple replacement for a compatible 30W soldering iron. It gives you a targeted way to restore cleaner soldering performance without replacing the full tool.
Its value is strongest for light electronics repair, occasional hobby work, and basic DIY soldering. It is not the best fit if you need a heavy-duty tip, a station-specific cartridge, or a wider tip shape for larger heat-demanding joints.
How It Compares to Alternatives
Compared with wider chisel tips, this uxcell conical tip gives you more control on small contact points but less surface area for larger joints. Compared with cartridge-style tips used on many soldering stations, it is simpler and more affordable, but only useful if your iron accepts this shank design.
The best alternative depends on your iron. If you need more heat contact, compare chisel or bevel tips that fit your exact tool. If you use a temperature-controlled station, look for the official tip series made for that station.
