Dremel always amazing
Great tool to use. A bit bulky but 12v supply with 35000rpm still available its worth it. However keep in mind that Amazon US supplies at 110V so make sure when ordering. I am still looking for a replacement charger to get the battery charged it is so upsetting......

Faulty
Absolute junk. I should have returned it immediately. It turned in approx 30% of the time I tried to use it

Selling second hand items
The item received is pre used, it’s came in original packaging however once opened the item had scratches everywhere and was clearly used a lot before. Quite disappointing as I know have to pay to return the item in order to get a refund!

IMPORTANT! If your tool is flashing green when it is turned on, set it 10 to 15k and try again. Toggle on and if it still flashes try again. Now to the review. This is a great tool. It's got plenty of power and can SAND through a board. Not just cut. With a SANDING DRUM you can go through a board. It doesn't bog easily above 10krpm. It is great for cutting bolts, cutting sheet metal, sanding metal and wood, rough and fine shaping in wood. Fine shaping in aluminum, polishing steel, rough axe or lawn blade sharpening, engraving, and much more I haven't done yet. The battery life is good, but it leaves some to be desired. It can be gripped like a golf club for grinding, and shaping, or like a pencil for fine and detailed work. The battery charges in 30 to 40 minutes. It is quite heavy, but not enough to stop most detailed work. I can't say much about durability, as I've only had it for a week, but I've got it covered on sawdust, metal dust and splashed with water lightly. This is a brushed tool, but there is not a way to change brushes, so I guess you replace it. Fine with me for 70$, but might be a deal breaker for some to replace every 150 hours. It is a great starter dremel though. You will have to buy a lot more accessories to fuel your rotary addiction, but at this price it's pretty easy to. The carrying case is a huge bonus. It fits my 110 piece accessory kit with the charger, tool and battery. I overall, a great buy.

This is my second Dremel, the first being a hundred years old :-} and corded. This one has WAY more power. The new EZ-Lock cutting wheels and mandrels are superior to the old mandrel mounted ones -- cut maybe five times faster. Really. This battery-operated tool is significantly bigger than my old corded one, so is a little more awkward to use, but I can get used to that. LOVE the power, LOVE not having a cord. The nose piece just below the collet unscrews and becomes a collet wrench -- brilliant! No separate wrench needed to change bits (but you still need one to futz with mandrels). Easier to take with me than the corded one--no extension cord. Comes in a nice (but bulky) fabric case with a few accessories No flex shaft, but I have one from my older Dremel tool. I use a Dremel tool on almost every project -- to cut, to sand, to polish. I have the carving burrs and use those often in woodworking. I bought this tool so that I could have two tools, each with a different bit, to save swapping bits in and out, not thinking that it would replace my old corded Dremel, but it certainly has. IMO the 8250 or 8260 are over-priced. The 8240 is not brushless, but I'm not worried about that. And who really needs to control a Dremel tool with a phone? Like, come on! The short story: BUY THIS TOOL.
