Bit Types for Rock Polishing

"Hi, I am Jason with expertvillage.com. Today we have started the rock charm for a necklace and we have done the cutting the major cutting we are ready for polish we have done all the edges and we are ready for drilling and everything. But before we do any of that I am going to go over the bits just a little bit. The bits for rock, well for any carving the lower the number the higher, the sharper the tool is so this would be two twenty that is one of the things that we want to use first. Two hundred and twenty grits on that sand paper, then we have got six hundred grit which is the next one. The we have eight hundred grit which is there and then we have twelve hundred which is the last for the polish. And when you buy these you need to make sure you get either diamond or silica carbide anything else will just blow up on rock. No matter how cool you try to keep it so when you go out to look for you bits and they are about three dollars a piece. They are about twice as much for silica carbide or diamond but it won't work if you don't get them. And the other thing that you want to do before you actually start with you bits is that you want to make sure that you have plenty of sand on them, sandpaper on them. This one looks like it is starting to wear just a little bit you can see the pink down in here that is actually the paper but there is still plenty on it for the most part so we should be able to use this one. This one is fairly worn but it will actually work better. The higher the grit when it goes on the rock will actually make new scratches where this one is worn down. It still cuts still polishes without making new scratches. I will talk about each one just a little bit as we go before we start but we'll start with the two twenty."
