This is the one tool that I use on almost every project. (OK except the screwdriver but I have lots of them and only one of these) With the right attachments it is just amazing what you can do with this. Here are a few of the jobs I've done with this tool. 1. Cut through the hinges on a Ford Explorer to replace the bushing and fix my door that would no longer lock because it was out of alignment. (This would have been a dealer job because without cutting the hinge the bushings were not accessible) 2. Cut through the frames of "poured in" basement windows for removal. (I swear it worked better than the reciprocating saw.) 3. Cut open a sealed AC adapter to repair what could no longer be purchased. Then ground off the edges to reseal it. 4. Cut off a nail protruding from my concrete basement floor. ( I have absolutely no idea why it was there) 5. Reconfigured a video game charger/stand to accomodate additional accesories. (lots of grinding) 6. Trimmed and shapped plastic moulding. (no other tool worked as well. It saved the day on this project) I have used it for so many projects, but the ones above are a good sampling of the many uses I've put it to. At the risk of sounding like a television commercial, "It's uses are only limited by your creativity". Every time I find myself puzzling over a project, I inevitably reach for the dremel. It NEVER EVER lets me down. It is a wired electric tool so the power is very good. The speed is adjustable which is handy. I suggest goggles when using any dremel tool. I HAVE been hit in the face with debris. Also I should point out that I have all the tools necessary for grinding, cutting, scraping, sanding,drilling etc. I use the dremel by choice not because I lack other more powerful tools. It's just THAT handy. There is a newer model available called the Dremel "Oscillating Tool" and while I definitely want to get one of those I would still suggest this one as a sort of foundation tool. I am waiting for a sale to "upgrade", but I'll never get rid of the 300.
