Bosch Professional 18V System Cordless Circular Saw GKS Review UK 2026

Key specifications

Build Quality and Design

Built for jobsite use, the Bosch circular saw (model 06016A2101) uses a tungsten carbide handle, selected to handle frequent contact and wear during cutting. The compact body measures 17.3 L x 14.2 W x 9.4 H cm, and the tool weighs 5.7 kg, helping with control during layout work and repeat cuts. The design focuses on safety and control with a fast motor brake and stable guide rail compatibility.

Battery System and Run Time

Battery options and run time are tied to The cordless tool's 18V platform. That matters because the GKS 18V circular saw (model 06016A2101) is designed as a cordless tool rather than a corded one. The Bosch supplies 2 battery pack(s), so work can continue by swapping packs so another charges. The saw body is listed at 5.7 kilograms, with batteries included in the kit, but the article does not specify battery capacity or runtime. Users should plan around battery availability, especially for long guide-rail sessions.

Power and Torque

Power and torque are presented mainly through the saw's cutting capability and its protection features rather than through battery or motor specifications. For the cordless tool professional 18V system cordless circular saw (GKS), the key signal is "power" as cutting performance, with cutting depth up to 57 mm and guide-rail compatibility for stable work. A notable protection element is the fast motor brake, which stops the blade immediately to reduce risk during handling. Torque feel and cutting power also depend on the material and setup, so rough alignment can limit results. Overall, the focus is on clean guide-rail cutting, alongside sensitivity to setup.

Speed and Versatility

For line-guided cuts on material up to 57 mm, it supports fast setup with guide rails, including compatibility with The Bosch 06016A2101 Professional 18V guide rail systems and also Mafell, Festool, and Makita guide rail systems. This rail-guided approach reduces the need for repeated re-measurements because the rail locks the cut path. Cut speed will still depend on the user's feed rate and blade choice, using the supplied 165 x 1.7/1.2 x 20 mm 36-tooth blade.

Ergonomics and Weight

For a tool used to make long, straight cuts, how it sits in the hand matters as much as how reliably the line stays on target when guide rails are used. The Bosch is rated at 5.7 kg, which has a direct impact on handling during extended use, particularly when working overhead. Measuring 17.3 x 14.2 x 9.4 cm, the body feels compact, but the overall weight still dominates balance. A tungsten carbide handle is included, providing a solid grip. Managing fatigue depends on good support of the work and keeping both hands on the handle while guiding the saw with rails.

What's in the Kit

Inside the box for the cordless tool 18V circular saw kit, the contents are aimed at getting started with guided, straight cutting. Included is an L-BOXX 238 (1 600 A01 2G2) with an inlay, along with the circular saw blade for wood (165 x 1.7/1.2 x 20 mm, 36). A dust extraction adapter, an internal hexagon, and a parallel guide are also supplied. The Bosch package is designed to be straightforward, while essentials such as guide rails are not listed.

Compatibility with Other Tools

Tool compatibility is a key consideration with the cordless tool (06016A2101), particularly for users who already own guide rails for straight, controlled cuts. This cordless tool is designed for use with The Bosch guide rail systems, and it is also stated to work with guide rail systems from Mafell, Festool, and Makita. A user should check the rail joining fit, align the saw shoe to the rail, and confirm cutting depth, since the maximum cutting depth is up to 57 mm. When comparing the Bosch 06016A2101 Professional 18V with other rail setups, matching the guide rail system is therefore important.

Cleaning and Maintenance

Cleaning and maintenance help the cordless tool (06016A2101) keep delivering accurate, clean cuts, particularly when used with guide rails for straight work. For this cordless tool system cordless circular saw, unplug the battery before cleaning. Remove dust from the base plate and around the blade guard. After cutting wood, clear the dust extraction adapter and check the internal hexagon area for debris. Inspect the blade for resin build-up and wipe it carefully to protect cutting lines. When storing the tool in the L-BOXX, keep surfaces dry to help prevent corrosion.

Who Is This Tool For?

It is aimed at cutting wood up to 57 mm, particularly when paired with guide rails, including The Bosch and compatible systems from Mafell, Festool, and Makita.
