Perfect. Adjustable diameter and it also has the plastic tray underneath, you don't lose anything. Cuts very well and effortlessly.

The truth is that it is a bit difficult for gypsum board. You will do your job, but with the classic trowel, you will do it much better. The blades loosen after 2 holes and need tightening with a wrench.
The only positive thing is that with this, you can adjust the dimension you want without buying trowels, with 30 euros, but the issue is for it to work without causing trouble. Only for false ceiling with mineral fiber due to the material. It is wrongly recommended for plaster. I expected something better from Milwaukee. It is better for those who are considering it to go for a trowel.

I do not recommend it for anything more than mineral fiber. I used it to make holes in plasterboard with a diameter of 80mm and unfortunately it broke after 10 holes. Firstly, the cutting is not as clean as with a drill bit, it took more time to make the hole compared to a regular drill bit, and overall it is not as sturdy as it should be. The blades became dull and the drill bit came loose. The only positive thing I can say is that it does not create as much dust as a drill bit, but unfortunately it does not work. I threw it away on the first day and bought a regular drill bit
