The Bosch GWS 9-125 S Professional Angle Grinder, 900 W, 125 mm is a corded model for grinding, cutting, and deburring. Its 125 mm disc format suits general workshop, construction, and installation work. The 900 W motor reaches a maximum no-load speed of 11,000 RPM, supporting material removal and cutting across metal, stone, and tile. Mains operation provides a continuous power source for regular use. This specification is aimed at tradespeople, workshops, and experienced DIY users completing metalworking or renovation tasks.
At 1.9 kg, the grinder remains manageable during repeated cutting and surface preparation work. A protective guard helps shield the operator from the working accessory and debris.

An included auxiliary handle provides an additional grip point for maintaining control during use.
