Our Shinano 5" Self Vacuum Dual Action Sander SI-3111M is a power tool used for sanding surfaces with an integrated dust collection system. It features a dual-action (DA) mechanism, which means the sanding pad both spins and orbits, reducing swirl marks and creating a smooth finish. The self-vacuum function helps collect dust while sanding, improving visibility, air quality, and cleanliness.

1. Dust Collection: Built-in vacuum system collects debris without needing an external vacuum.
2. Dual Action Motion: Combines rotation and orbiting movement for a swirl-free finish.
3. Ergonomic Design: Lightweight and easy to handle for extended use.
