## Description

4” Flat Grinding Machine Stone Rock Polisher, Grinder, Shaper Shaping and Polishing Tools, Mineral Rock Polishing Machines, Grinding Machines

Review: Easily assembled and easy to run and have fun with. - Very easy set up, instructions are well laid out. It's my first attempt at this, and I discovered right away I should have gotten the 6" model rathr than 4" - as 4" means the working surface is a mere 2" - 4" being the diameter of the sanding disk. Still...am having great fun with it and starting with smaller stones is working well for a beginner like me.
Review: Worth the investment for small projects!! - Great product for beginners, it's well built for the price and works well for its size!! I have been using this for a while now and it's holding up very well!!
