HARDELL Mini Cordless Rotary Tool, 5-Speed and USB Charging Rotary Tool Kit with 69 Accessories, Multi-Purpose 3.7V Power Rotary Tool for Sanding, Polishing, Drilling, Etching, Engraving, DIY Crafts

Love love love this little device!! Small and fits comfortably in my hand. Lightweight so easy to hold from different angles. Holds its charge nicely. Love the 5 option speeds. And as I did not delve into it before buying - I was happily surprised that it has a light pointed directly at the tip so I do not need to worry about a strong and strategically located/positioned light source. I enjoy it so much that I actually do a good work as the use is easy so I have more patient and attention span for detailed work. Addictive due to its ease of use, small size and little weight in compared to other hand held similar tools.Thinking of purchasing another one - just in case since for me it is a life changing experience compared to previous tools I used and I would not want to get stuck without one for any reason.Did not get oaid for this review.Just very impressed.

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

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.

I’ve been using this HARDELL mini rotary tool for just a week now and I’m seriously impressed. I wasn’t sure what to expect from something this compact, but it’s way more powerful than I thought. The 5 speed settings give me a lot of control, and it’s perfect for all the little projects I do, from sanding and polishing small 3D prints to engraving stuff for gifts.It’s super easy to use, charges fast with USB, and the battery lasts surprisingly long for how small it is. Plus, it came with a bunch of accessories, which is awesome I haven’t even gone through all of them yet.If you’re doing any DIY, hobby work, or just need something portable for fine-detail tasks, this is totally worth it. 10/10 would buy again.

This little tool is fantastic! So versatile and I use it for so many different things. Originally purchased for doing touch up of rust on a vehicle and it performed well! Love the fact that it is cordless and compact. Not very noisy at all
