HARDELL Cordless Rotary Tool, 5 Variable Speed Mini Rotary Tool Kit with 69 Accessories, 3.7V Type-C Charging Power Rotary Tool for Engraving, Sanding, Polishing, Carving, Cutting, DIY Crafts

Good for it's purpose.I bought this to work with plastic models and 3d prints and it's good for that. low power setting is low enough power it doesn't "oversand" when removing mold lines or layer lines.I had previously found other drills and name brand rotary tools like Dremel sometimes actually have too much torque for my applications. This on the low setting is really manageable.the set comes with a nice variety of sanders and bits. It's a decent product for the price point. build quality is relatively solid, nothing overtly janky about the unit itself.I have a few little gripes - the chuck stop/brake that lets you change the bit looks and feels a bit like a control and pressing it with the unit running will, uhm, "tend to induce malfunction" shall we say. So don't do that.The unit locks on, it's not press to operate/release to stop. I consider this a feature, not a bug, and the tool is generally low powered enough I don't find a huge safety fault with it, but it doesn't make it a little less child safe/idiot proof than it could be if that was a selectable feature or a mandatory one.I think the overall torque level here might mean it's not a full blown replacement for a much more expensive rotary tool - if you want to cut a lot of metal or wood, you might burn this little dude out pretty fast. but for my purposes, so far, it's effective, just right power level, and intuitive, with the USB C charging. Comes in a decent little hard case with two little mini-sorters for the bits and sanders

First thing I noticed was how compact and light it is. It fits really comfortably in my hand, which is important when you're doing detailed work. The cordless design is a huge plus, too. No more wrestling with cords! The USB charging is also convenient; I can just plug it into my laptop or a power bank.The 5-speed settings are perfect. I can switch between them easily, depending on the task. I've used it for sanding some small pieces of wood, polishing some metal, and even tried my hand at some basic engraving. It handled everything surprisingly well.And let me tell you, the 69 accessories that come with it? That's a lot of stuff! I was a little overwhelmed at first, but it's great to have so many options. I've already found a few favorites for different tasks.It's definitely not a heavy-duty tool, but for small projects, crafts, and detailed work, it's perfect. I've been having a lot of fun experimenting with it, and it's definitely made some of my DIY projects a lot easier. If you're looking for a small, portable, and versatile rotary tool for your hobby projects, this HARDELL one is worth checking out. I'm glad I added it to my toolbox.

Edit May, 2025: I've used this for a while now and I wanted to come back and share my thoughts. I think whether or not this tool will be good for you depends entirely on what kind of work you're doing with it. I used the included saw blade the other day to make a few cuts in plastic and it worked great. No smoking, no heat, just a nice clean cut. I got a chance to use the sanding drums and they worked reasonable well too.The main thing is, if you are going to use it periodically, for 10-20 minutes of fine detail work on plastic, wood or soft metal you're going to love it. The variable speed control is really nice, it's mostly quiet and the battery lasts long enough for that.If you're going to use it on harder metals, for significant material removal or continuously for longer than 20 minutes or so between charges, I think this will be the wrong tool.------------Mostly it seems to work ok. You can tell it's a cheap tool but even so it it easy to use and convenient. I'm using it for very light duty, delicate work and for that it's just about perfect. The battery isn't super great, didn't get anywhere near the advertised 200 minutes of use. And that's with only using it on the second speed setting. After about 20 minutes, while it was still working, I could feel that it was starting to slow down a bit. By around 40 minutes I stopped to charge. If you use it on slow speed you can extend the use time by turning it up a few speeds as it wears down and it will still going the speed it had been when you started on the slowest.The included bits it comes with are basically for show, you should plan on bringing your own if you use it very much at all. The grinding stones chipped and wore unevenly and the "diamond/carbide" abrasive bits never really cut anything and wore down to smooth metal within minutes. The sanding drums might work? I haven't tried them.Anyway, all that to say, it does work and it is convenient. Just don't plan on hogging out material with it or using it for the hours at a time that it advertises. For light jobs every now and then I think it's going to do the trick.
