Weller LT KN 6.5 mm Knife 17 mm Soldering Iron Tip for use with WSFP/WSP80/WP80/WXP80, LR21/TCPS last generation

This soldering iron tip is a knife-shaped replacement tip designed for precision thermal work with compatible Weller handpieces. It serves as a direct consumable for temperature-controlled soldering tools and is intended for use in repair, assembly and rework environments where a flat, sharp-edge contact is required for efficient heat transfer.

• 6.5mm wide edge transfers heat across broader joints
• 17mm length allows access to recessed areas
• Knife profile enables controlled lateral solder spreading
• UPC approval indicates conformity with recognised standards
• Compatible with multiple tool types for field flexibility

• Suitable for fine solder trimming and joint reshaping
• Used with WSFP stations for handheld soldering tasks
• Ideal for rework on surface-mount components
• Can be used for precision desoldering and wick assistance
• Used with WP80 and WXP80 in maintenance settings

It fits a range of Weller handpieces including models listed for backward compatibility with recent generation connectors.

The flat, angled edge enables lateral heat application for smoothing solder fillets and removing excess solder without concentrated point contact.

It is compatible with last-generation LR21/TCPS connectors, permitting use across updated station variants.

The broader contact area reduces the time needed to heat larger pads, improving throughput on repetitive joint work.
