Small Universal Angle Grinder with Speed Control

The Bosch GWS 9-125 S Professional 0601396102 angle grinder is designed for working with attachments with a diameter of 125 mm. It is compatible with grinding discs up to 7 mm thick, cutting discs up to 3 mm, and wire brushes — disc-shaped up to 125 mm and cup-shaped up to 75 mm. The 900 W motor (450 W effective power at the gearbox shaft) ensures high performance when working with metal, stone, and other materials. For precise adjustment to specific tasks, there is a 6-stage speed controller (2800–11000 RPM) located on the rear part of the housing.

Compact and Convenient Tool

The Bosch GWS 9-125 S grinder is compact — its length is only 280 mm, and the housing is slimmer than most counterparts. This makes the tool easy to hold with one hand, which is especially important when working in hard-to-reach places. For two-handed operation, such as when cleaning or grinding surfaces, an additional handle that comes in the package can be screwed into the gearbox housing.

For Builders, Repair Specialists, and Other Craftsmen

This tool stands out for its excellent dust protection — key components, including the electric motor, bearings, power switch, and speed controller, are protected from abrasive dust. Because of this, the Bosch GWS 9-125 S Professional 0601396102 is suitable for cutting and grinding stone, brick, porcelain stoneware, tiles, and ceramic roofing tiles, as well as for cutting grooves in walls. It handles metal just as efficiently, making this model a universal solution for builders, installers, and repair craftsmen.
