Frequently asked Questions
What Does GSB Stand for in Bosch Drilling Tools?
In Bosch power tools, GSB stands for "Geräte Schlag Bohrer" in German, which translates to “Impact Drill” in English. This means:
- G = Geräte (Tool/Device)
- S = Schlag (Impact)
- B = Bohrer (Drill)
So, Bosch GSB drills are impact drills, designed to not only screw and drill into wood and metal but also impact drill into brick, stone, and concrete.
