If you are referring to the stone cutter that makes stone bricks and such, than that is only in pocket edition.
If you mean iron then I know what you are talking about. But you find it the same way you would in PC minecraft. Just make a stone pickaxe and try to find iron. You can find it almost at any depth. But you can find it from about -10 blocks to bedrock.
Try wooden tools if haven't tried those! If that doesn't help I don't know what to tell you bro!
