Bosch GGS 18V-10 SLC PROFESSIONAL Straight die grinder 10500 RPM Black, Blue, Red

The Bosch GGS 18V-10 SLC PROFESSIONAL is a cordless straight die grinder designed for precision metal grinding and polishing. It combines a brushless motor with a gearbox to deliver high torque at lower speeds and an idle speed of up to 10,500 rpm. The tool offers compact dimensions (80 mm width, 430 mm depth, 113 mm height) and weighs 1.6 kg. Sound power and pressure are specified at 79 dB. Powered by an 18 V battery and optimised for ProCORE18V technology, the grinder is compatible with the Bosch Professional 18 V battery system.

Advantages

The brushless motor provides efficient power delivery and reduced maintenance compared with brushed alternatives. The integrated gearbox produces higher torque at reduced speeds, making the tool suitable for demanding surface work with heavy brushes. A compact, well-balanced design helps with maneuverability in confined spaces. Electronic user controls allow selection of different speed settings, and the model includes PROtection features such as KickBack and Drop Control, Brake System and Restart Protection to support safer operation. Preparation for Bluetooth® connectivity enables status monitoring via a compatible smartphone when used with supported accessories.

Suitable for

• Fine grinding of metal components and weld seams
• Polishing and surface finishing of steel and non-ferrous metals
• Working with rotary brushes and abrasive tools that require controlled torque
• Maintenance tasks in workshops where cordless mobility is needed

How to use

Fit an appropriate grinding or polishing accessory in accordance with the accessory manufacturer’s instructions and ensure the accessory is secured correctly. Install a compatible 18 V Bosch Professional battery and select the desired speed setting using the tool’s user interface. Hold the grinder with a stable two-handed grip, position the accessory against the workpiece, and apply steady, controlled pressure; allow the tool’s torque and speed to perform the work rather than forcing the accessory. Observe the built-in safety systems (KickBack and Drop Control, Brake System and Restart Protection) and follow all safety practices for powered grinding tools, including the use of personal protective equipment.

Recommendations

Use ProCORE18V or other Bosch Professional 18 V batteries for optimum performance. Select abrasives and brushes rated for the grinder’s speed and the material being worked on. For extended work sessions, monitor battery temperature and follow battery manufacturer guidance for charging and cooling. Always use eye, hearing and respiratory protection and secure the workpiece before starting grinding or polishing operations.
