This is a heavy duty complete unite for lapidary and glass. It is versatile, clean, quiet, and easy to use. It comes with a 5 step accessory kit. It is designed to be a commercial unit, but is affordable enough for a hobbyist and is completely portable ( for the snow birds who like to take their hobby with them!!). You can grind flats, free form cabochons,, do intarsia, and detailed inlay work. Excellent for glass work. Easy clean up.
