Can You Polish Rocks With A Dremel? I Tried It

Hello. I am going to be trying to polish some of my rocks that I found at Bodega Bay Beach for goat rock. I found these. I want to try to see about polishing them a little bit more. I am using my Dremel 4000 sanding bits that I'm going to try and use that I bought from Amazon. Comes from $50 all the way up to $10,000. Try and see about polishing this one first. This is one that One that I haven't done yet. I feel that this one feels a lot more smoother than this one. I know at least something's working. Moving on to the 150, 1,000. Into the 1,500, 2,000. 5,000, the 6,000. Into the 10,000, I am starting to noticing some shine. Should have probably looked earlier. Here's on to the final one, 10,000. You see the shiny is really smooth. With the water, it does help make it, like I've sprayed some stuff on there. Once it dries up, it doesn't look as shiny. So I've heard that I guess if you get mineral oil, I did notice using the bits here sanding, it pretty much stayed on the whole time that I was doing it. The only time I noticed something that was a little off was when I used the 800, but other than that, it stayed on. Clean the shaft really did help. I know that my hand would have been very sore if I would have used just this part. Using the shaft, did help. Look forward to trying it again and perhaps trying this one and how this one would look. I would like to try this one. That one would also turn out too. I've got quite a few collections here of just rocks that I collected once again at Goat Rock in Bodega Bay. I've got plenty more to try to see about polishing up. I'd say using the Dremel did work. It is time consuming. You do have to take a break. I had to get up at least twice now. Because of my back, but other than that, I had a good time trying out my first time using the Dremel on the sanding, polishing up some rocks. Thanks again, I hope you enjoyed.
