How it fits the work

The long slim flat can reach a recessed pad where a short LT tip stops against a housing. Compare it with LT M when the joint has room for a broader face. Check the dimension drawing if reach is critical because the listing and Weller chart give different length callouts.

Care for the working face

Weller recommends leaving the working face tinned while the tip is idle and wiping it just before use. Follow the cleaner and tip-change directions for the fitted pencil. Care instructions

Questions before buying

Is LT K the narrower long chisel than LT L?

Yes. The Weller chart gives LT K a 1.2 mm width and LT L a 2 mm width. Check the side drawing separately if working length is the deciding measurement.
