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

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.

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!!

Love this for grinding, cabochons flat. Works really well, and the price point is perfect for a hobbies.

Decent price compared to other options for wet grinders of similar size, but this unit is hugely underpowered. The wheel would stall under light pressure and an intense burning smell would come from the motor consistently during use - even after a break-in period. I am returning the unit, as it did not perform as advertised.

It’s dose a great job for small stones!!!!
