    Default Any idea what this is?

    I cleaned up a special device and took some pictures.
    Internally there are 6 different spirals, marked with 80, 100, 120, 160, 180 and 200.
    With the pin on the side, by pressing, you can choose to take the path of one of these spirals with you.
    On the front there is a cylindrical hole of 16 mm where, for example, a cutter can be secured with a socket.
    At the rear there are 24 notches divided over 360 °, so that a rotation can be made every 15 °.
    Can it be a spiral grinding attachment?
    I will post more pictures on another post
