Founded in 1932, the Wisconsin-based Dremel company is a power tool manufacturer perhaps most notable for its selection of rotary tools. The company's more powerful rotary tools grind, sand, polish and cut through a number of surfaces, including stone. In addition to basic rotary options, Dremel offers a small selection of other tools suited for light stonecutting tasks. Remember to practice proper safety--including wearing protective eyewear--when cutting any sort of stone.
