    Common Questions

    Q:

    Is it possible to polish Stones with this, like Lapis, Tigers eye, etc.

    A:

    It depends on how smooth the surface is to start with, and Lapis and Tiger eye are soft semi-precious gems, so should be polished when freshly cut.

    You can't polish a metal surface unless you remove metal.00001", which is one tenth of an inch.
