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 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.

The Einhell Power X-Change 150mm Cordless Circular Saw is a compact and lightweight tool designed for DIY enthusiasts and home users who need a handy saw for wood cutting. Its 150mm blade offers a decent cutting depth of up to 48mm at 90 degrees, which is suitable for most household woodworking tasks. Being battery-powered with an 18V system, it provides the convenience of cordless operation and matches other tools in the Power X-Change family, but it requires purchasing the battery and charger separately. The saw runs at a respectable speed of 4200 RPM, helping to deliver clean and efficient cuts.

One of the user-friendly features is the tool-free adjustment for cutting depth and tilt angle, making it quick to set up without extra tools. The built-in LED light improves visibility on the cut line, and the dust extraction attachment helps keep the work area cleaner, which are great touches for safety and convenience. The saw’s aluminium base adds stability and durability, while weighing 2.45 kg, it remains manageable and easy to control during prolonged use.

Since the battery and charger are not included, new users must invest a bit more upfront. The blade size, while suitable for smaller jobs, limits cutting depth compared to larger circular saws, so it may not be ideal for heavy-duty or thick material cutting. It is primarily designed for wood, so it might not perform well with other materials. This saw serves as a solid choice for casual wood cutting projects and those already invested in Einhell’s battery system, blending portability with practical features, though it’s not meant to replace more powerful or professional saws.
