The Mirka® PROS 680CV (Central Vacuum) Pneumatic Random Orbital Sander is ideal for finishing operations that require a larger, 8mm sanding orbit for aggressive sanding. The PROS has optimized ergonomics that makes it comfortable to grip and user-friendly for longer operating periods. In addition, the Mirka® PROS features a new, quick-connect fitting for the dust extraction hose and a unique shroud system with a brake seal that allows minimal internal air leakage for improved dust extraction, even at low suction power.
