Mirka 3" × 4" Pneumatic Sander with Self-Generating Vacuum, 3mm Orbit

With a tight 3mm orbital pattern that leaves smooth, even surfaces, combined with a compact 3" × 4" platen that has bevelled sides to permit precise sanding right up to an edge, this is a superb sander for finishing work. Effectively dust-free in use, it has an onboard dust-collection system that lets you work independently of a separate vacuum.
