Angle Grinder Bosch GWX 17-125 PSB

The Bosch GWX 17-125 PSB angle grinder is a compact, corded grinding and cutting tool designed for professional and advanced DIY use. It features a powerful brushless motor with an input power of 1700 W and a maximum no-load speed of 11,500 RPM. The tool accepts 125 mm (12.5 cm) grinding discs with a bore of 22.2 mm and combines a lightweight design of 2.3 kg with a slim housing in blue and black for improved handling during extended tasks.

Advantages

The brushless motor delivers sustained power and reduced maintenance compared with brushed alternatives, while the 1700 W input ensures high performance on demanding materials. The relatively high no-load speed supports efficient cutting and grinding action. Weighing 2.3 kg and featuring a compact form factor, the grinder is easier to maneuver in confined spaces and during overhead or vertical work. The standard 125 mm disc size provides broad compatibility with common abrasive and cutting discs.

Suitable for

• Cutting metal and steel sections
• Grinding welds and removing rust
• Surface preparation on concrete and masonry
• Sanding and shaping metal or stone with appropriate discs

How to use

Before use, fit a suitable 125 mm disc that matches the intended task and verify the disc's bore fits the 22.2 mm arbor. Secure the disc with the appropriate flange and tighten according to the tool instructions. Connect the grinder to a compatible 220–240 V AC power source. Hold the tool with both hands—one on the main body and the other on the auxiliary handle—maintaining a firm grip and stable stance. Start the grinder and allow it to reach full speed before engaging the workpiece. Move the disc smoothly across the surface, applying steady, moderate pressure; avoid forcing the tool. After finishing, turn off the grinder and wait for the disc to stop completely before setting it down or changing accessories.

Usage recommendations

Use discs rated for the grinder's maximum speed and select abrasives appropriate for the material. Wear suitable personal protective equipment including eye protection, hearing protection, gloves and respiratory protection when working with dust-generating materials. Maintain ventilation and secure the workpiece before cutting or grinding. Allow the motor to cool during prolonged heavy use and inspect discs for damage before each use.
