This tool allows you to "break in" a pair of 930 CVs. It's a diamond impregnated rubber material on a 1/4 inch mandrel for use in a die grinder. It allows you to polish the factory rough surface where the balls ride to avoid material being deposited into the grease that would normally wear quickly in the "CV break in period". This allows you to run the CV much longer before an initial service. It also allows for higher joint angles before bind if the CV is being used in high articulation applications. I polish all new GKN CVs before first use with this tool. It is time consuming, which is why we don't offer joints already polished, but relatively easy to do. One "stone" lasts about two CVs worth of polishing. See the how to video for more details.
