There’s a power switch on the front of the handle, it’s just a simple on/off slider switch.
On the rear of the handle you have a push button for changing speed levels, and an LED screen for displaying the battery level – a simple 25%, 50%, 75% and 100% indicator.
There are multiple cooling vents on the body.
To install the drill bits/accessories, simply loosen the nut, insert the shank into the collet and tighten the nut.
It’s “self-locking” so you don’t need to worry about the nut not being tight enough, it makes changing accessories fast and easy. The chuck specification is 2.3mm/3.3mm.
There’s an LED ring around the spindle that lights up when it’s running, which is helpful for seeing what you are working on more clearly.
It can be recharged via the USB-C port on the back.
Get This or the Dremel?
The Dremel is way more powerful and versatile, but they also tend to be very heavy, big, more expensive and has a dangling power cord. Check out dremel rotary tools on Amazon (affiliate link).
If you want something that is portable for some small and precise jobs, then the Greenwork 8V is a good option.
Here’s a size comparison with my daily cordless drill (affiliate link) which has been a great tool to have for me.
With the Greenwork 8V, the saw blades and some other accessories are pretty low quality and wear out quite quickly. You can however, get some good quality ones for the Dremel (affiliate link) and use them on the Greenwork 8V. Make sure to wear safety glasses when using this type of tools to avoid injury!
For most things in RC and FPV, the Greenwork 8V is plenty in my opinion, like cutting carbon fibre, wood, plastic etc. It’s useful for grinding/polishing carbon fibre and plastic too. You can use it for drilling holes as well, but there’s only one drill bit included so you need to get your own if you need other sizes. I wouldn’t use it for large projects that require hours of work as the battery probably won’t last that long before you need to charge it, but it’s certainly a handy tool to have when you just want to cut something small and don’t want to be limited by the power cord.
