HARDELL Mini Cordless Rotary Tool Kit, 5-Speed and USB Charging with 61 Accessories, Multi-Purpose 3.7V Power Rotary Tool for Sanding, Polishing, Drilling, Etching, Engraving, 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

Last month, I wanted to make a custom wooden name sign for my sister’s birthday. Nothing too fancy—just something personal. I picked up this little HARDELL mini rotary tool, not really expecting much because of its size. But wow, it surprised me!It’s super light and cordless, which made it really easy to hold and move around, especially since I’m still new to this kind of thing. I used the engraving tip to carve her name, then smoothed out the edges with one of the sanding heads. It even comes with 69 tiny attachments, and switching them out was simple. I charged it with a USB cable while I was getting everything set up, and it lasted through the whole project.Long story short, she loved the sign, and I felt like a crafting pro. Now I use it to fix little things around the house, polish jewelry, and even clean up my old model cars.If you like DIY stuff, crafts, or just want a handy tool that fits in your hand and actually works—this one’s a solid pick

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.

This Dremel tool is top notch! I absolutely love how it performs. It's cordless, keeping a cord out of my way. It has a very bright LED light to light up what I'm working on. I love the ease it takes to operate it. It's very lightweight and comfortable to grip. It's very accurate and has plenty of power. I used it to polish a coin. I'm a collector. My app that determines the quality of a coin guess my penny to be worth .91 cent to $1. After polishing the coin, my app recognized the coin at mint shape. Highly recommend and the seller is great with fast shipping and a great product. Especially for the small price I paid for it. I will refer others to get one and I will get another one just like it if this one happens to break!
