This is a great set of cutting tools. They all seem to have some sort of rust remover that should be scraped off completely. When used without cleaning, the heat from metalworking captures the small screw that holds the carbide insert in the holder. This makes it almost impossible to remove to swap out the insert. Once that's done, you won't be able to find better tools than these.
