The Mirka PROS 680NV (MRP-680NV-G) is a 6 in. pneumatic non-vacuum random orbital sander engineered for high-capacity material removal and aggressive surface preparation in industrial woodworking, metalworking, composite, and automotive finishing operations. Powered by compressed air, this sander features an 8 mm orbit that delivers rapid stock reduction while maintaining manageable handling during demanding sanding tasks.

Developed by Mirka's engineering team for continuous shop use, the PROS 680NV incorporates a low-profile, symmetrical body that provides balanced control in either hand. An integrated wrist support cover channels muffler exhaust air away from the operator during use, shields the air line connection, and serves as a safety lockout lever. A built-in pad brake system restricts free-spinning rotation when the tool is lifted off the surface, preventing deep scratches or gouging when re-engaging the workpiece.

Features & Benefits

• 8 mm Orbit: Delivers an aggressive sanding pattern for rapid material removal and large-surface preparation.
• Dual Backing Pad Inclusion: Supplied with both grip (hook-and-loop) and PSA (peel-and-stick) backing pads for complete abrasive attachment versatility.
• Lightweight Ergonomic Design: Weighs 2.09 lbs. to minimize hand and arm strain during continuous sanding operations.
• Symmetrical Housing: Low-profile construction and balanced weight distribution allow comfortable control with either hand.
