The Bosch GWS 9-125 Professional Angle Grinder 900 W 125 mm is a corded model for grinding, cutting, and sanding suitable materials. Its 125 mm disc suits general metalworking, workshop, and maintenance tasks. The 900 W motor runs at a maximum no-load speed of 11,000 rpm. This delivers the speed needed for standard grinding and cutting discs. Mains operation avoids the runtime limits associated with battery-powered grinders.
At 1.9 kg, the grinder is manageable for extended jobs and work in different positions. Its ergonomic palm-grip design gives a defined gripping area around the body. An auxiliary handle is included for two-handed control during cutting and material removal. The protective guard can be repositioned to suit the working angle and direct debris away from the operator. Restart protection prevents automatic start-up after a power interruption.
