A compact and powerful cordless straight grinder with a long lifetime. The GGS 18V-20 Professional’s brushless motor is optimised for ProCORE 18V battery technology, giving it cordless power equivalent to that of a 700W corded grinder. Compact and light at 310-mm long, with a small grip size of 156 mm and weighing just 1.2 kg, it is easy and comfortable to use even in overhead applications. The brushless motor and overload protection ensure a long lifetime. Using high-quality grinding stones, the GGS 18V-20 Professional is perfect for grinding metal. It is compatible with all Bosch 18V batteries (except ProCORE 18V 12.0 Ah) and chargers. The restart protection safety feature prevents the grinder starting unexpectedly after a power interruption.
