The Bosch GWS 18V-10P PROFESSIONAL angle grinder is a cordless tool with a brushless motor designed for demanding grinding and cutting tasks. It accepts a 125 mm (12.5 cm) grinding disc and delivers up to 9,000 RPM no-load speed for fast material removal. The tool combines compact dimensions (approximately 267 mm width and 108 mm height) with a light weight of 1.9 kg, providing improved handling during extended use. Powered by an 18 V battery, the grinder offers portability for on-site and workshop applications while maintaining professional-grade performance.

Advantages

The brushless motor increases efficiency and reduces maintenance compared with brushed designs, prolonging runtime per battery charge and improving durability. The compact and lightweight construction reduces operator fatigue and helps with precise control in confined areas. High no-load speed supports faster grinding and cutting progress, and the cordless design eliminates the restriction of power cords, allowing greater freedom of movement on job sites. Durable materials and ergonomic colour-coded housing support reliable everyday professional use.

How to use

Install a compatible 125 mm grinding or cutting disc according to the manufacturer's mounting instructions and ensure the disc is rated for the intended operation. Fit a charged 18 V battery and check the grinder's guard and side handle are securely positioned. Hold the tool with both hands, allow the motor to reach full speed before contacting the workpiece, and apply steady, controlled pressure without forcing the disc. After use, switch off the tool, wait for the disc to stop fully, and remove the battery before performing disc changes or maintenance.

Recommendations

Use appropriate personal protective equipment including eye protection, hearing protection, gloves and respiratory protection when generating dust. Choose discs rated for the material and the grinder's maximum speed. For consistent battery life and tool longevity, avoid prolonged continuous heavy loads, allow the motor to cool if working on long tasks, and follow Bosch battery and charger guidelines.
