  • What buyers say about Dremel 421 Polishing Compound

    It arrived on time as described and was just as good as a store at std retail stores.

    Excellent results can be achieved from a wide range of uses.

    I think the job was done well for that mirror finish.

    It works for me in my hobby activities, polishing gun triggers and feeding ramps.

    It works as expected.

    Common Questions


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


    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.


    Can I use this for a feeding ramp?


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


    Is it possible to use this as a final polish on agate?


    We don't recommend you use 400 grit polishing compound for a finishing compound.


    Is it suitable for polishing glass?


    Dremel 421 polishing compound is not able to polish glass.


    Can anyone give me a description of the size of the grit and what material it is?


    The compound is 400 grit and has a high degree of Silicon Carbide and a low degree of vitrified bond.
