The new Dremel 400 Series XPR Rotary Tool is fantastic for working on jewelry. It replaces the much more expensive flex shaft tool seen as standard equipment at most jeweler's benches. It's range of speeds from 5,000 to 35,000 RPM's is more than adequite to get the job done right. The Dremel 400 Series comes with the flexable shaft attachment, circle cutter/strait line guide, garden tool sharpener attachment, 51 accessories (tips, wheels, cutters, sanders, etc), and the Dremel 400 Series XPR Storage Case which will hold every one of the Exclusive XPR system attachments. Add the foot pedal speed controler, available through Dremel's website, and the 400 Series is as versitile as and of the expensive flexshaft machines. I got mine for Christmas and have not been able to put it down for more than 5 minutes. With all the accessories available this tool replaces a whole shop full of power tools. And ofcourse it also comes with Dremel's 5 YEAR limited warranty. That's quality and a great value. Look for them to start showing up on your jeweler's bench soon.
