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......

It's a Dremel rotary tool -- does what it is supposed to do
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.

Why did it take me so long??
First time purchasing a CORDLESS Dremel - have 3 older corded. I have to say this was a smart choice. So much power! I’m taking my time working up to full throttle 😅 and the battery is still more than half after three separate uses with just one charge! Extremely versatile (slices through pvc lattice like butter). Great quality and weight for short or long work sessions. Noise is minimal and will vary somewhat in relation to power level and duration of use. The only thing I could ask for is a slightly better body. I have big hands (6’ woman) and it is a bit thick around the middle- not unreasonably so - just asking for a little better ergonomics when holding, like a slightly deeper pinch nearer the head for when a detail grip is desired ( I get that there has to be room for the battery to insert and yes, I own the grip attachment - not a favorite of mine). Otherwise, it is simply everything one would expect from the Dremel brand - including an excellent price. By the way, the original Dremel in my toolbox is at least 15 years old and still performs admirably within it’s abilities. Upgrading to cordless, though? Wow. Awesome! This was an actual purchase and I was not paid for the review.
