Bosch Professional, GKS 18V-51, 18 V, 140 mm Cordless circular saw

This cordless circular saw is designed for straight cuts in wood, plywood, and OSB panels. It delivers a maximum cutting depth of 51 mm at 90° and 35 mm at 45° for a range of timber sizes. Power comes from an 18 V lithium-ion battery driving a brushless motor. The motor runs at a maximum no-load speed of 6300 rpm, maintaining steady cutting performance across different board thicknesses. It is intended for construction, renovation, and installation work where portability and reliable power are needed.

The tool is supplied as a bare unit, meaning the battery and charger must be purchased separately. A 140 mm Eco for Wood blade with a 20 mm bore is included, so work can begin straight away on site. At 2200 g, the saw is relatively light for its class, and the soft-grip handle improves operator comfort. A dust extraction port and an integrated dust blower work together to keep the cutting line clear of sawdust. The ergonomic body design helps maintain control during overhead or awkward angled cuts, reducing fatigue.

• 30-tooth blade configuration – produces a clean finish in wood and composite panels.
• Built-in LED light – improves visibility of the cutting line in low-light conditions.
• 1.7 m/s² vibration level in wood – minimises hand strain during prolonged use.
• Soft start – limits initial torque for controlled starting.
• Quick-stop function – rapidly halts the blade after a cut for added safety.
• Bosch 18 V battery platform compatibility – works with existing batteries and chargers from the same manufacturer.
