Circular Saw Bosch GKS 18V-57-2 Professional

The Bosch GKS 18V-57-2 Professional is a compact cordless circular saw with the blade mounted on the right, designed for efficient sawing of wood and wood composites. Powered by an 18 V battery and a brushless motor, it combines portability with strong cutting performance. The 165 mm blade enables a maximum cutting depth of 57 mm at 90° and the tool is optimized for cordless operation to balance fast cutting progress with extended battery runtime.

Advantages

The brushless motor provides reliable power and durability while reducing maintenance. A rotatable 360° dust port connector compatible with Click & Clean improves dust extraction efficiency and user protection. Additional built-in features include a fast brake, dust blower, LED light for improved visibility, a front handle for better control, spindle lock for quick blade changes and the option to attach a separate rafter hook.

Suitable for

• Straight crosscuts and rip cuts in solid wood and wood-based panels
• On-site carpentry and framing where cordless mobility is required
• Tradespeople who need a compact saw for tight spaces

When it may not be suitable

This compact circular saw is intended for wood and wood-composite materials and is not designed for continuous heavy-duty cutting of metal, masonry, or concrete. For very deep cuts or large-format sheet processing where greater cutting depth or higher blade diameter is required, a larger stationary saw or a higher-capacity cordless circular saw may be more appropriate.

Key specifications

• Blade diameter: 165 mm
• Maximum cutting depth at 90°: 57 mm
• Rated voltage: 18 V (battery-powered)
• Sound power level: 104 dB
• Sound pressure level: 93 dB
• Brushless motor
• 360° rotatable dust port (Click & Clean compatible)
• Fast brake, dust blower, LED light, front handle, spindle lock
• Compact design for use in confined spaces

How to use

Fit a suitable 165 mm blade and ensure the spindle lock is engaged when changing blades. Mount an appropriate 18 V battery (use ProCORE ≥ 5.5 Ah for maximum performance) and check that the dust port and any extraction hose are correctly connected. Before cutting, set the required cutting depth and angle, secure the workpiece, and use the front handle to maintain steady control. Engage the saw, allow the blade to reach full speed, and feed the saw steadily through the material. Use the dust blower and LED light to keep the cut line clear and visible.

What to consider before purchase

• Intended material: optimized for wood and wood composites, not for metal or masonry
• Battery compatibility and desired runtime; higher-capacity batteries increase performance
• Required cutting depth and blade diameter relative to your typical tasks
• Noise levels: check hearing protection due to sound power and pressure levels

Usage recommendations

For best results use high-quality, sharp 165 mm blades suitable for the specific wood type, secure the workpiece firmly, and use an extraction system compatible with the Click & Clean connector to reduce dust exposure and maintain visibility while cutting.
