A great tool!
If you haven’t used a Dremel before – it is actually noisy/loud.
A huge bonus point: Dremel and Bosch are using the same 12V batteries.

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.

For small rotary tools, Dremel is the Cadillac and this is the top of their line. I already had a 4000, which is almost the same, but corded, but I needed the added portability. Under normal loads, the 8240 feels just as powerful as its corded sibling.
One complaint is that the cloth case isn’t as sturdy or practical as the plastic case that came with the 4000 and the 8240 is thicker than the 4000, so I can’t just carry it in the 4000 case. That isn’t serious enough for me to deduct a star.
A more important complaint is that not all of the attachments for the corded Dremel fit on the cordless Dremel. The flexible shaft and the mini circular saw, for example, fit the corded model, but the connector is too small to fit the cordless Dremel’s shaft. I’m guessing that this is because using these attachments would add resistance that would drain the battery faster, or possibly exceed the available power. I deducted one star for this lack of versatility. If you need to use such attachments, go for a corded model, like the Dremel 4000.
The added girth may be uncomfortable for some people. If you have small hands, this tool may feel too big for you. There are smaller, but weaker models available. I prefer to have the extra power and larger battery, even if the tool is chunkier.
So, for me, it’s a great addition to my corded Dremel 4000, and it’s very useful for some types of work or when a power cord just isn’t practical. But it doesn’t entirely replace the corded model, as I would have hoped. There are still things that the corded model can do that this one can’t.

I was really on the fence about going cordless with this Dremel Tool but wow! Power to spare!
Not only power but a fully charged battery lasts quite well.
The advantages are obvious,
* quickly unpack and use anywhere, no need for a plug-in
* despite the battery (extra weight and girth), it still is comfortable to use
* easily cuts off small bolts, plastics
* a huge assortment of bits, grinding, polishing, cutting attachments available at most hardware stores
* comes with a nice soft case, battery, and charger

The Dremel 8240 is a great upgrade, plenty of power, smooth variable speed, and the comfort grip makes longer projects easier. The 12V battery lasts a good while and recharges quickly. Perfect for DIY and hobby work, I reach for it all the time.

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.

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……

Love this cordless dremel! It’s much quieter than my old corded dremel and makes trimming my dog’s and bird’s nails much easier.

I bought this cordless rotary Dremel to replace my old one which was stolen. The first thing I noticed is this newer model seems well made (more solid than my old model). I’ve already used it a couple of times and it works great. The price wasn’t bad either. I’m very happy with it.
