Review on Effortless Sanding with Dremel EZ407SA Drum Sanding Mandrel by Will Schimmel

As soon as I saw this unit was available I ordered it. Like anyone who has bought a Dremel tool, you know that you need that tiny screwdriver handy to change the grinding tubes. This makes the tool easier to use. The only thing I noticed with this is that the tube moves up a bit when you use metal grinding wheels. I don't see that as a big problem, you just have to keep an eye on the drum.
