Mirka AROS-B

Switching to cordless tools is a proven way to streamline many surface treatment processes in automotive manufacturing and collision repair. With AROS-B 325 and 350, Mirka introduces a long-awaited series of battery-powered random orbital sanders perfect for spot repairs, body-in-white sanding, and post-paint applications. Designed for maximum mobility, these lightweight, low-vibration tools provide greater material removal than a denibber but less than a traditional grinder. Both AROS-B sanders feature a 77 mm (3”) backing pad. The difference between the two machines is the sanding orbit. AROS-B 325 has a 2.5 mm orbit, making it the top choice for detailed sanding applications, while the AROS-B 350 offers a 5 mm orbit for a more aggressive cut.
