Great tip for a great iron. The iron came with a similar sized conical tip, but for me, I like a tip with a bit of an edge to it, so that it can fit just a bit more snug into the corner between a component leg and the pad of the pcb. This tip allows me to do that with precision, and has excellent heat transfer, almost to the very end of the tip, but not quite. Can't comment on how long it will last, but I'll buy another of these when this current one wears out. Recommended!
