This is an incredibly useful tool, and I’ve found the selection of attachments which accompanies it to be quite good. I bought this to use on a boat and I’ve found a million things to repair I didn’t know needed a Dremel tool! It cuts and grinds stainless steel bolts more easily than anything I’ve seen, never mind bronze, fiberglass, wood, etc.
The battery, though, is what makes it both unique and frustrating. Of course being able to use the tool unfettered by a cord is great, and it does recharge reasonably quickly in about three hours. On the other hand, the motor is not as powerful as the corded variety, and the speed is not continuously variable. I haven’t yet found either of these to be a problem. But you cannot get a half-hour of use out of a fully-charged battery. Fifteen minutes is more like it. This is plenty of time to practice home dentistry skills on the dog if you are so inclined, but it means that unless you have a battalion of extra batteries at $26 a pop you will not be able to grind out all the grout in your bathroom, cut more than ten ceramic tiles, or buzz off more than a few square inches of rust from your car from a single charge. If you are buying the tool for those sorts of projects you need the corded flavor.
I have a line powered Dremel but I most often grab for this rechargeable unit because its easier to handle without the cord. It is great for tight spots in the car. I recently upgraded the intercooler piping in my car and needed to enlarge a 2″ hole to 3″ diameter. I just used the cordless Dremel to make numerous radial cuts and bent the “tabs” back. I would have gone nuts trying to cut that out with a hack saw or file! I always use it at the full 15 krpm speed and don’t miss a variable control at all.
My friend lost his special “antitheft” key wrench for his license plate mounting bolts. I just used a cut-off wheel to make two cross cuts in the (round) bolt heads, and unscrewed it with a Phillips head screwdriver. Without a Dremel, it would have been tough.
The battery life is short, but I always have an extra charged battery ready. If I’m working with it alot, I just rotate the batteries through the separate wall mounted recharger.
It can also be used as a printed circuit drill or for other small precise drilling. Much easier to handle than a typical hand drill for light work.
It does kick up some metal bits so use eye protection!
