Picked during Prime Deals and have no regret.
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.

Impressive
This thing is impressive. I got another version of the cordless dremel and was disappointed. This one is as powerful as the corded, quieter than the corded and works as any of the dremel

Powerful Cordless Dremel Perfect For Chain Saw Sharpening
Excellent Cordless Dremel tool that I purchased for sharpening my chain saws using a Dremel optional kit yet of course works with most all the other dremel accessories, blades, disks etc. Battery charges easily in its own charger and enables the tool to function at 35K easily. While more costly than a corded model the portability more than makes up for this. I have not expeienced any overheating. While the tool is a bit larger than a corded model I would order it again if needed.

Great tool, but some ghosts remain
It's mostly a great tool, except for one long-standing issue: When you're doing intensive, detailed work, you're all but guaranteed to press the collet lock button, which makes a horrible grating sound and may stop all tool motion leading you to think that you've just broken it! I just can't believe that this is still an issue after all these years. I can see how it might be difficult to relocate it, so put a cover over it or make it a slide switch or something else that doesn't engage merely by holding the tool!

Great for indoors or outdoors!
The Dremel 8240 is a cordless, battery operated tool, that can be used indoors and outdoors equally well. It is powered by a 12v Lithium-Ion battery with home charger, extra batteries can be purchased for more outdoor time. The tool has variable speed from 5,000 to 35,000 rpm controlled by a small rotary dial. Build quality is very good ant these tools will stand up to hard wear. Very easy to use, the size is not much longer that the ac mains version. The design looks very good with its two tone light and dark grey body. For its size it is very light weight and it works great. I love it as I can usit for little jobs on my car as well as the workbench. I would advise owners to invest in a Dremel 3-jaw chuck wich makes using small drills a lot easier. Great tool highly recommended.

A Wireless Dremel Version, Priceless!
This is a quality tool that's easy to use, has a long battery life and because it's 'wireless' is very functional outdoors when I work on my vehicle away from electrical power sources. No cord to get in the way either. Thumbs Up!

Good so far
Needed to replace my Bosch which is identical. Disappointed in the short life of previous tool but figured this purchase gives me replacement tool and battery with charger compatible with my other 12v tools. So far so good with limited use.

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......

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.
