10 Best Mini Circular Saws

The Ryobi R18CSP-0 is a cordless mini circular saw powered by an 18V battery, offering good flexibility and portability without the hassle of cords. It features a 150mm carbide-tipped blade with 18 teeth, suitable for making clean, straight cuts on timber and plastic. The saw's motor runs at 4,700 RPM, providing enough speed to handle trimming tasks on kitchen worktops, doors, and windowsills. It can cut up to 45mm deep at a straight 90-degree angle and 32mm at a 45-degree bevel, which is adequate for most small to medium woodworking jobs.

The saw’s weight is around 3.13 kg, which is manageable but might feel a bit heavy if used for extended periods. The plastic handle is designed for comfort, though it lacks detailed information on advanced ergonomic features or vibration reduction. Safety-wise, the saw includes typical protections like a blade guard and a side fence for guided cuts, but it does not highlight extra safety technologies beyond standard industry practices.

This model is sold as a bare tool, meaning the battery and charger are not included and must be purchased separately or borrowed from other Ryobi 18V tools. This makes it a great choice for users who already own Ryobi ONE+ batteries and want a versatile, cordless circular saw for general DIY and light professional use. It may not be the best fit for those seeking an ultra-lightweight design or advanced safety features, but it serves well for hobbyists or home users needing cordless convenience and decent cutting power.

The Bosch Professional 18V System Cordless Circular Saw GKS 18V-57 G is a versatile tool ideal for wood cutting tasks. It features a 165 mm tungsten carbide blade, providing a sufficient cutting depth of 57 mm which is suitable for most woodworking projects. Powered by an 18V battery, this saw offers the convenience of cordless operation, making it highly portable and useful for on-the-go tasks. However, it is worth mentioning that the battery and charger are not included in the package, which may incur extra cost for users who do not already own compatible batteries.

The motor reaches a no-load speed of 3,400 RPM, making it efficient for quick and smooth cuts. Weighing 5.7 kg, it is relatively heavy for a mini-circular saw, which might affect prolonged use and handling comfort. On the positive side, the design incorporates ergonomic features such as the plastic handle, aiding in better grip and control. Safety is enhanced with the integrated electric brake function, ensuring a prompt stop of the blade for user protection.

The AMPShare system allows compatibility with other Bosch Professional 18V tools, providing flexibility for users who own multiple Bosch tools. Despite the high user ratings and reliable performance, the noise level at 44 dB might be noticeable. The inclusion of the L-BOXX, dust extraction adapter, and other components add value, making it a comprehensive set for professional or DIY enthusiasts.

The Einhell Power X-Change 165mm Cordless Circular Saw is a compact and lightweight option, weighing just 2.72 kg, making it easy to handle for home and garden tasks. Its 165mm blade size is ideal for smaller, precise cuts in wood, with a maximum cutting depth of 54mm at 90° and 35mm at 45°, which suits most DIY projects but may be limiting for thicker materials. Being battery powered (18V) and part of the Power X-Change family allows battery sharing with other Einhell tools; however, the battery and charger are sold separately.

The motor is rated at 18 watts, suitable for light to medium cutting but potentially struggling with heavy-duty applications. User-friendly features include tool-free cutting depth and angle adjustments, a spindle lock for easy blade changes, an LED light for better visibility, and a dust extraction adapter to help keep your workspace clean. The ergonomic design features a thermoplastic elastomer handle for a comfortable grip.

This saw is designed for hobbyists or casual users needing a handy, portable circular saw for woodworking and general home maintenance tasks. It is less appropriate for heavy professional use or cutting very thick materials due to its power and cutting depth limitations.
