Bosch Professional GBR 15 CA Concrete Grinder, 1500 watts, 125 millimetres

The Bosch Professional GBR 15 CA Concrete Grinder is a corded 125 mm grinder for surface preparation, renovation, and material-removal work. It is designed for grinding concrete and other demanding mineral surfaces. The 1,500 W motor runs at a no-load speed of 9,300 RPM, delivering the steady material removal needed for high-speed surface grinding. AC mains power makes it suitable for sustained work near an electrical supply, without the limitations of battery runtime or charging.

At 2.6 kg, the grinder is manageable for jobs requiring repeated movement across a floor or wall, though its weight still matters for extended overhead or vertical use. Soft start limits the initial speed rather than applying full motor power at once. Restart protection prevents the grinder from starting unexpectedly after a mains interruption. The stated grinding vibration level of 4.5 m/s² allows operator exposure to be compared with other models.
