Review on 🔧 Premium URBEST 5 x Replaceable Iron Tool Solder Tips for Efficient Soldering Station (30W) by Matt Jenkins

This is about 1cm less than what it takes to replace the original nozzle that came in my Harbor Freight soldering iron. However, I inserted this bit with enough headroom to get the job done and it was able to melt the solder. I didn't try to actually solder the joint, just checked that it was hot enough to melt the solder without pushing it all the way into the iron. I think if you're cheap enough (or use it infrequently enough) to use a $10 soldering iron from Harbor Freight, it should work.
