    I used this to grind the threads on a bolt that was damaged on my fwd drive shaft. Attached this to my rotary tool that I also purchased from Amazon and this did the trick. Just make sure to use cutting oil and keep it lubed while in use.

    Don’t mistake this for the B218, I was looking for the buttress thread version. I have not tried it out.I have used it now a couple times, it works, but I find it is more controlable at at drill speeds than die grinder speeds.
