The MIRKA® ROS 150NV (non-vacuum) 32 mm finishing sander is lightweight at under 0.5 kg, with a maximum speed of 8000 rpm. The MIRKA® ROS 150NV has a 5.0 mm orbit; the levers for different orbits are colour-coded, 5.0 mm being the black lever. The MIRKA® ROS 150NV has a quick-lock backing pad that is fast and stable to use. It leaves a finer scratch pattern, making it ideal for sanding smaller areas.
