AROS-B 325 and 350 – Increase Your Sanding Mobility

19 June 2025

Switching to cordless tools is a proven way to streamline many surface treatment processes in industry and collision repair. With AROS-B 325 and 350, Mirka introduces a long-awaited series of battery-powered sanders with low vibration levels and smooth mobility.

Expanding the Mirka Power Tools Ecosystem 

The AROS-B 325 and 350 are Mirka’s new, cordless random orbital sanders. They have a smaller orbit than Mirka’s cordless polishers and greater mobility than traditional electric sanders. AROS-B 325 has a 2.5 mm orbit, and the AROS-B 350 has a 5 mm orbit.

The new sanders feature a 77 mm (3”) backing pad and a brushless 12 VDC motor. They are fully compatible with the myMirka app and use the same quick-charge batteries as Mirka’s popular cordless spot repair sanders and polishers. 

Recharge Your Sanding Capabilities

The AROS-B sanders are designed for unrestrained mobility. They are ideal for spot repairs and body-in-white sanding, providing greater material removal than a denibber but less than a traditional grinder.

Thanks to their impeccable sealed design, these sanders are shielded from dust and water and perfectly suited for wet sanding applications like post-paint sanding and denibbing. 

For those looking to speed up their sanding processes and improve workplace ergonomics, the AROS-B 325 and 350 are a welcome addition to the workshop or industrial facility.

Key Features

  • Convenient cordless mobility
  • Lightweight and ergonomic design
  • Low-vibration sanding that prevents user fatigue
