Circular Saw Bosch GKS 18V-70 L Professional

The Bosch GKS 18V-70 L Professional is a cordless circular saw designed for professional woodworkers and tradespeople who need high cutting performance and portability. Powered by the Bosch Professional 18 V battery platform and equipped with BITURBO Brushless technology, this left-blade circular saw delivers cordless cutting power comparable to a 1,800 W corded machine. The saw accepts a 190 mm blade and achieves a maximum cutting depth of 70 mm at 90° while offering an ergonomic auxiliary handle for precise control in all cutting positions. Integrated dust extraction compatibility and a compact package size make the tool suitable for use on job sites and in workshops.

Advantages

BITURBO Brushless motor technology provides high cordless cutting performance equivalent to a powerful corded saw while maintaining the benefits of battery operation. The left-mounted 190 mm saw blade and an auxiliary handle ensure good visibility of the cutting line and ergonomic control. Built-in features such as a fast brake, overload and restart protection, spindle lock and LED work light increase operational safety and convenience. A 360° rotatable dust port connector compatible with Click&Clean and dust bags helps keep the work area cleaner.

How to use

Fit a suitable 190 mm saw blade according to the material and fastening instructions, and ensure the spindle lock engages before changing blades. Mount a compatible Bosch 18 V battery, ideally a ProCORE18V ≥ 5.5 Ah for maximum performance, and check that overload and restart protection settings are active. Adjust the cutting depth and angle to the required setting, connect a dust extraction hose if needed using the 360° rotatable dust port, and position the auxiliary handle for best control. Power the tool and allow the motor to reach full speed before making contact with the workpiece, maintain steady feed speed, and let the fast brake stop the blade after the cut is completed.

Usage recommendations

Use appropriate personal protective equipment (eye, ear and respiratory protection) due to the saw's sound levels and dust generation. For best cordless performance on demanding cuts, use Bosch ProCORE18V batteries with a capacity of 5.5 Ah or higher. Connect to a suitable dust extraction system or use compatible dust bags to reduce airborne dust. Follow Bosch safety instructions and local regulations when operating the tool.
