Mirka AROS-B is a sensational sander that will save untold time and effort!
I spend hours on manually sanding the curves in the depressions I route in my charcuterie boards as there's just no other way to do it, using the AROS-B sander I can now do a full board in around 20 minutes and then have it ready to oil! I estimate it's saving me at least 3-4 hours per board.
Expensive tool but it reall works fantastic with a lot of grunt, and saves an incredible amount of time and effort! I love it so much a week later I bought the AOS-B as well!
Couldn't recommend this unique sander highly enough for fiddly awkward sanding jobs!
I received my mixed box of 125mm Mirka Galaxy discs from Best Abrasives a little while ago...that stuff is amazing!
I let the 80 grit go on a piece of rough sawn Camphor Laurel and it was smooth in a couple of minutes. Very impressive compared to other brands...I'll be back for more! 🙂

The Abranet Ace disk cuts very nicely not a lot of swirl marks just typical Mirka precision
Long lasting, don’t clog, compatible with the foam interface, these are the best sanding sheets I’ve ever used, especially when using a dust extraction device
