The Dremel 400 Series XPR rotary tool is an essential part of the do-it-yourself fanatic’s tool collection. Whether you’re installing computer parts or doing mundane fixing tasks at home, this tool can prove to be very useful. With the several attachments available, you’ll be able to convert this simple tool into whatever you need. The available attachments also leave you with many choices, ranging from a circle cutter, planer, jigsaw, and a flex shaft. This makes the tool handy when it comes to trimming and shaving corners, as well as shaping small objects. A vacuum molded case holds all of the accessories and parts, but the reviewer claims you need a few tries when it comes to fitting them all in. The reviewer notes that if the case were much more practical, it would be a great improvement on the tool’s overall functionality.
