Weller KDS1912P Soldering Iron Needle Tip 0.04 in 50-pack

Product Description

The WELLER KDS1912P is a needle-style soldering iron tip designed for precision soldering work requiring extremely fine point contact. With a tip diameter of 0.04 inches, this tip delivers targeted heat to small pads, fine-pitch leads, and tight component placements where a standard tip would cause bridging or collateral heat damage. It is sold in a pack of 50 units, making it practical for shops and service benches that cycle through needle tips frequently. Electronics technicians, PCB rework specialists, and trade professionals working on delicate assemblies will find this tip suited to high-accuracy applications.

The KDS1912P needle tip is intended for use in applications where pinpoint soldering is required, such as surface-mount rework, micro-connector installation, and fine-wire terminations. The 0.04-inch diameter point allows access to densely populated boards and connectors that standard conical or chisel tips cannot reach cleanly. The Luer Lok syringe compatibility noted in the spec data also indicates suitability for flux or solder paste dispensing applications in conjunction with compatible dispensing equipment.

Key Features

• Needle tip geometry with 0.04-inch tip diameter for ultra-fine soldering work
• Compatible with Luer Lok syringes for dispensing applications
• Pack of 50 units supports high-volume bench or field service operations
• Lightweight at 0.05 pounds per unit, minimizing iron handle fatigue during detailed work
• UNSPSC Code 23271809 for procurement and catalog classification

Compatibility

Designed for use with Luer Lok syringes and compatible WELLER soldering iron handles that accept needle-style tips. Verify tip seat compatibility with your specific iron model before installation.

Installation Notes

Needle tips should be installed and removed only when the soldering iron is fully powered down and cooled to ambient temperature to prevent burns and tip damage. Use the appropriate tip extraction tool or pliers with a protective cloth — avoid gripping the tip directly with bare hands or metal-jaw tools that can deform the fine point. Tin the tip immediately after installation to prevent oxidation. Follow applicable workplace safety standards when working with soldering equipment at elevated temperatures.
