The Mirka Roundy is a purpose-built ergonomic hand sanding block engineered for efficient, dust-controlled manual sanding across a wide range of surface preparation tasks — from aggressive paint stripping to fine lacquer and paint sanding.
Designed to sit comfortably in the palm, the Roundy delivers excellent control and even pressure distribution, reducing operator fatigue during extended use. Its rounded profile allows sanding discs to wrap smoothly around the sides of the block, enabling improved access to corners, edges, and tight or contoured areas that are difficult to reach with standard flat blocks.
Equipped with 34 integrated dust extraction holes, the Roundy ensures optimal airflow and effective dust capture when connected to a compatible dust extraction system. It is fully compatible with Abranet® net abrasives as well as standard 150 mm 15-hole discs, offering flexibility across abrasive systems without compromising performance.
Two interchangeable vacuum hose plug adapters are included, allowing quick and secure connection to most dust extractors for a cleaner, safer working environment and improved abrasive longevity.
The Mirka Roundy delivers professional-grade performance in a compact, highly adaptable manual sanding solution.

Great bunch of people to deal with

Absolutely stellar customer service, well above par and enjoyable as much as helpful, and the products are 10/10 - will be back again and again and again…
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! 🙂
