Bosch GGS 18V-23 PLC Professional Straight die grinder 23000 RPM Black, Blue, Red, Silver 1000 W

The Bosch GGS 18V-23 PLC Professional is a straight die grinder designed for precision grinding, deburring and surface finishing in metalworking and similar trades. Its brushless motor delivers a maximum idle speed of 23,000 RPM while running on an 18 V battery platform, offering cordless freedom without compromising performance. At 1.4 kg and with a compact straight-body design, the tool provides accessible handling in confined spaces and over prolonged tasks. The grinder accepts an 8 mm collet and is intended for use with standard rotary and grinding accessories.

Advantages

The brushless motor increases efficiency and reduces maintenance needs compared with brushed designs. High maximum speed enables fast material removal and fine finishing, while the cordless 18 V operation removes restrictions from mains power and improves portability. The light weight and slim form factor support precise control and reduce operator fatigue during extended use. A sound power level of 83 dB helps to characterise workplace noise for planning hearing protection.

Suitable for

• Precision grinding and deburring of steel and non-ferrous metals
• Removing weld splatter and preparing weld seams
• Shaping, finishing and polishing small components
• Work in confined spaces where a straight die grinder fits better than a right-angle tool

How to use

Fit the correct 8 mm collet accessory for the application and ensure the accessory is properly secured before operation. Install a compatible 18 V battery and check that the battery is charged and locked into place. Start the grinder and allow it to reach operating speed before applying it to the workpiece; use light, consistent pressure and maintain steady movement to avoid gouging. Release the trigger and allow the tool to come to a complete stop before setting it down. Observe general safety practices for grinding tasks, including use of eye protection, gloves and appropriate clothing.

Recommendations

Use accessories rated for the tool's maximum speed and select abrasives suitable for the material being worked. For prolonged tasks, plan battery rotation to maintain consistent power and consider vibration-damping gloves to reduce operator strain. Keep ventilation and dust extraction in place when grinding materials that generate fine particles.
