Bosch GKS 18V-57 G Professional 16,5 cm negro, azul 3400 rpm

The Bosch GKS 18V-57 G Professional is a cordless circular saw designed for precision cutting in wood and wood-based materials. With a 165 mm blade diameter and a maximum no-load speed of 3,400 RPM, the tool delivers consistent cutting performance and a maximum cutting depth of 57 mm at 90°. Powered by an 18 V Lithium-Ion battery system and supplied with two batteries, the saw offers mobility and the ability to maintain work continuity on job sites where a mains connection is not convenient.

Advantages

The tool combines compact dimensions with a professional cutting capacity: its 165 mm blade enables accurate straight cuts while the high idle speed improves cutting quality and feed rate. Battery operation provides freedom of movement and reduces dependency on extension cables, and the inclusion of two batteries extends uninterrupted operation. Ergonomic design and balanced weight contribute to operator control and reduced fatigue during prolonged use.

Suitable for

• Cross-cutting and rip cuts in solid wood and plywood
• On-site timber trimming and framing work
• Carpentry tasks where cord-free operation is preferred
• Workshop use for panel cutting and small joinery projects

How to use

Fit a blade compatible with the saw’s 165 mm diameter and ensure it is tightened according to the manufacturer’s instructions. Charge the supplied batteries fully before use and install one battery into the saw until it locks. Set the cutting depth and guide fence or baseplate to the required position, mark the cut line on the workpiece, and clamp the workpiece securely. Start the motor, allow the blade to reach full speed, then feed the saw steadily along the cut line while maintaining control of the baseplate against the workpiece. After completing the cut, release the trigger and wait for the blade to stop before setting the tool down and removing the battery if required.

Recommendations

Use blades rated for wood cutting with the correct tooth count and carbide tips for the best finish. For longer continuous operation, alternate between the two supplied batteries and keep a spare charged. Use appropriate personal protective equipment (eye protection, hearing protection, and dust mask) and secure workpieces with clamps. For angled cuts or deeper sections, verify the depth and angle settings before cutting and perform a test cut on a scrap piece.
