The large 4 1/2" x 9" (115 x 228 mm) sanding surface and a 3/32" (2.5 mm) sanding stroke makes the RS 2 the perfect choice for fine sanding large surfaces. Typical applications include intermediate sanding of varnished doors, leveling large surfaces, and fine sanding of delicate stock. An additional ergonomic hand grip enhances controllability and reduces fatigue during long sessions. This sander is especially good for applications that require an absolutely even surface (like tabletops).
