Bosch GTR 550 Professional Drywall Sander

The Bosch GTR 550 Professional 215 mm AC Mains Drywall Sander is designed to prepare plasterboard, drywall joints, walls, and ceilings before painting or finishing. Its 215 mm sanding disc covers broad surfaces, unlike the narrow working area of a straight grinder or die grinder. The 500 W motor reaches a maximum no-load speed of 910 RPM. This combination supports controlled material removal over large areas. Power comes from an AC mains connection, so operation does not depend on battery capacity or charging. The tool is a dedicated drywall sander rather than a general-purpose cutting grinder.

At 4.8 kg, the sander's weight is an important consideration for prolonged wall and overhead work. An ergonomic handle is provided to support controlled handling during longer sanding sessions. The body measures 1,730 mm high, 250 mm wide, and 210 mm deep. Its extended format differs from that of a compact handheld sander and should be taken into account when moving the product around a worksite. The width and depth also give concrete reference points when planning storage space.
