Rotary Tool, Zaeel Mini Electric Rotary Grinder Multi-Functional Rotary Tool Kit, Adjustable Speed 3000-20000 RPM for Polishing, Engraving Grinding and Sanding, with 56 Accessories & Storage Case

I initially bought this product because of the various tool bits which I could use as spares for my trusty Dremel the price was a deciding factor. It didn't matter to me that the Grinder might turn out to be useless. If you look at the label on the Grinder it states Manicure & Pedicure which is telling of its true purpose more so by design. I've seen videos regarding this exact product coloured PInk with fewer tool bits demonstrated for use on fingernails and it is shown to work very well. I was surprised at how this product actually performs and it's performance when used for fine detailed work in my case for finishing and refining my 3D model Printing. It can be used for cutting certain types of materials without the motor stalling but don't expect to cut heads off thick six inch nails. This product is great for Manicure and Pedicure but also for model makers and hobbyists to create fine detail in their creative works. Sometimes it is very handy to have a more gentle tool that's as easy as writing with a pen and yes with the correct tool bit you can engrave. The variable speed control is a nice addition and gives me much needed control for all the fine detail. Well worth the money just for the tool bits alone.

I only brought this for one job and needed cutting discs. Once I'm through the bars that's it! Seriously through now I have to buy cutting discs too....

The fact that the label on it refers to polishing nails should be a giveaway. It might just have enough torque to polish your toe nails but for anything else it’s useless. As soon as any of the supplied tools touch something it stops. There’s more umph in my electric toothbrush.The supplied attachments aren’t up to much either. Either the exception of the grinding/ polishing heads, which may at least attempt to do the job if the tool had enough torque to keep them spinning, everything is pretty poor quality and I doubt would achieve any of the desired functions.My gran used to say you get what you pay for. Well in this case you don’t even get that.

This tool works very well. Runs off the USB connection on my laptop (is powered directly by USB, rather than being rechargeable). Variable speed motor, tool is much better quality than I expected from the price. I use it for small-scale jewellery making - burring down excess solder, filing, smoothing & sanding. Includes a good selection of heads - burrs, grinders, sanders & brushes. Good tool for hobby-scale jewellery and very good value. Arrived quickly & exactly as described.

It's cheap and does what it should, no good for cutting. Ok

Brilliant value...from filing your nails to etching your jewellery

Total waste of money, wouldn't drill through a thin shell, no power, better of using a powerdrill with a very small fitting

I thought it has battery inside but unfortunately if you want to use it should be pluged in all the time.There is no charger just a cable.
