Bosch GWS 12-125 S 06013A6020 angle grinder

Compact power for precision processing

The Professional series angle grinder, model GWS 12-125 S, is a tool designed for demanding tasks where not only raw power but also control and ergonomics matter. Thanks to a rated power of 1200 W and a maximum rotational speed of up to 11 000 rpm, the device effectively handles cutting and grinding even hard materials. Crucially for installers working in hard-to-reach places – it is the lightest and narrowest grinder in its power class. Such dimensions allow for a secure grip and easy maneuvering of the tool during overhead work, vertical work, or working from within, which is often impossible with larger models.

Safety and comfort during long working hours

Working with an angle grinder involves the risk of kickback and hand fatigue caused by vibrations. This model solves these problems through advanced safety and comfort systems. The KickBack Control function automatically detects a sudden disc blockage and switches off the motor, protecting the user from sudden tool movement. Meanwhile, the side handle equipped with the Vibration Control system reduces vibrations by approximately 20% compared to previous models, significantly reducing joint strain during multi-hour operation. Additional protections include soft start (preventing jerking upon startup), restart protection (protecting against accidental startup after a power failure), and an overload switch.

Durable construction and versatile application

The tool has been designed to withstand heavy workshop and construction conditions. A durable metal collar protects the gearbox from mechanical damage, and a special labyrinth-type ventilation hole design effectively dissipates heat and prevents dust accumulation inside the motor. This translates into a longer service life for the device even under intensive load. Thanks to the speed regulation (range 2800–11 000 rpm) and the standard M14 spindle thread, the grinder is versatile – it can be adapted to various types of discs (Ø 125 mm) and materials, from steel to ceramics or stone. The set includes a complete guard, an open-end wrench, and an additional anti-vibration handle, allowing for immediate start of work without the need to purchase additional accessories.

The device's technical parameters have been optimized for performance: a motor with a power of 1200 W ensures high efficiency under heavy load, and speed regulation in the range from 2800 to 11 000 rpm enables precise work with different materials. Versatility of application is guaranteed by the standard M14 mounting for discs with a diameter of 125 mm. The low weight of the device, amounting to 2,2 kg, minimizes operator fatigue during work. The noise level during operation is 93 dB(A) sound pressure and 104 dB(A) sound power, while during surface grinding, vibration emission oscillates around 5,9 m/s² (with a margin of error of ±1,5 m/s²).
