Bosch GWS 20-230 J angle grinder 23 cm 6500 RPM 2000 W 5.5 kg

The Bosch GWS 20-230 J angle grinder is a heavy-duty grinding and cutting tool designed for demanding metalworking and construction tasks. Powered by a 2000 W motor, it delivers high torque and a maximum no-load speed of 6500 RPM. The grinder accepts 230 mm (23 cm) grinding discs and features a robust metal gear housing and ergonomic main handle. With a net weight of 5.5 kg and compact dimensions (approximately 500 mm wide and 240 mm high), the tool balances durability and handling for long operating sessions. The unit is mains-powered (AC) and is finished in Bosch's black and blue color scheme.

Advantages

The powerful 2000 W motor provides consistent performance under load, enabling fast material removal and efficient cutting. A maximum idle speed of 6500 RPM allows use of a wide range of abrasive discs for grinding, cutting and surface preparation. The large 230 mm disc diameter increases cutting depth and reduces the need for multiple passes. The solid build and weight contribute to vibration dampening and stable operation during heavy applications. Designed for mains power, the grinder offers continuous operation without battery changes or downtime associated with charging.

Suitable for

• Cutting steel profiles and reinforcing bars
• Grinding weld seams and removing rust
• Surface preparation before painting or coating
• Shaping and deburring metal parts

How to use

Fit the correct 230 mm disc type for the intended task, ensuring the disc is rated for the grinder's maximum speed. Securely tighten the disc with the supplied flange and wrench before connecting the tool to the mains. Hold the grinder with both hands using the main handle and, if provided, the auxiliary handle for better control. Start the grinder and allow it to reach operating speed before engaging the workpiece; maintain steady, even pressure and avoid forcing the tool. After use, switch off the mains, allow the disc to stop completely, and disconnect the power before changing discs or performing maintenance.

Recommendations

Use appropriate personal protective equipment including eye protection, hearing protection, gloves and a dust mask. Select discs suitable for the material and the grinder's speed rating. For prolonged cutting or grinding, take regular breaks to avoid overheating the motor. Ensure a secure workpiece and work in a well-ventilated area. Follow local safety standards and Bosch service recommendations for maintenance and inspection.
