The Bosch GSS 20‑18 A Professional orbital sander is a precision 200 W electric tool with a 90 × 183 mm sanding pad, excellent dust control, and low vibrations (3.0 m/s²) — ideal for sanding wood, panels, plaster, or preparing surfaces before painting.

The GSS 20‑18 A Professional (order code 0601070101) is a corded orbital sander designed for artisans, carpenters, restorers, and professionals seeking a robust and reliable tool. Thanks to its 200 W power and orbital motion with oscillations between 16,000 – 24,000 oscillations/min, it offers effective sanding on large surfaces or for finishing work.

The rectangular 90 × 183 mm sanding pad allows for efficient coverage of large areas, while the 2 mm orbit ensures homogeneous and uniform sanding. The balanced body with an ergonomic anti-slip handle reduces fatigue even during prolonged use or on large pieces.

To maintain a clean working environment, the GSS 20‑18 A features a highly efficient dust collection system — with a suction rate of 83.5% — and includes a detachable dust bag.

This version comes in a cardboard box, with a punch plate and dust bag: ready for use, both in the workshop and on site.

The GSS 20-18 A orbital sander is ideal for woodworking thanks to its hook-and-loop pad and perfect two-hand grip.
