Best Battery Kit: DEWALT 20V MAX 6-1/2-Inch Circular Saw Kit
The DEWALT DCS391P1 circular saw kit delivers impressive performance for both professionals and DIY enthusiasts. With 1,400 inch-pounds of torque and a 5,150 RPM motor, it provides smooth, accurate cuts through wood and other common materials. The 6.5-inch carbide-tipped blade ensures precision, while the brushless design enhances efficiency and reduces maintenance needs. The included 20V MAX XR 5.0Ah lithium-ion battery offers long run times, and the fast charger keeps downtime minimal. At 9 pounds, the saw has a solid build that feels sturdy in hand, and the brushed finish combined with ergonomic design makes it practical for extended use.
From a customer perspective, the kit is often praised for its reliability and cutting power, especially when portability is needed without a cord. The inclusion of the premium battery and charger makes it a ready-to-use solution straight out of the box. However, some users may find the weight tiring during overhead or prolonged cutting, and the 6.5-inch blade can be limiting compared to larger 7-1/4 inch models for deep cuts. Overall, this saw is a dependable cordless option that balances performance and convenience, particularly for those who value power and battery life in a portable package.
Best Cutting Depth: M18 Cordless Lithium-Ion 6-1/2" Circular Saw
The Milwaukee M18 cordless circular saw is built for users who need strong cutting capacity in a portable design. Equipped with a brushless motor and delivering up to 1,800 watts of power, it produces consistent performance across demanding tasks. The 7.25-inch high-speed steel blade with 24 teeth is larger than many cordless options, giving it an advantage in cutting depth and versatility. At just 8.43 pounds, the saw is relatively lightweight and compact, making it easier to handle while still providing professional-grade durability. The rubber and plastic handle ensures a secure grip during extended use, while the 18V platform integrates seamlessly with Milwaukee’s wide range of M18 tools.
Customers often highlight the balance between cutting power and portability, noting that it performs well for general construction, framing, and remodeling projects. The larger blade size makes it suitable for deeper cuts, a feature appreciated by professionals who need more flexibility. However, buyers should note that the tool is sold as a bare unit, meaning batteries and charger must be purchased separately, which increases the overall cost. Additionally, with a maximum speed of 3,500 RPM, it runs slower than some competitors, which may affect smoothness in certain applications. Still, for users already invested in the M18 battery system, this saw offers dependable power and excellent cutting depth in a compact form.
Best Safety Features: DEWALT 20V MAX XR 7-1/4" Cordless Circular Saw Kit XR POWERPACK

The inclusion of a brushless motor ensures long-lasting efficiency, while the electric brake adds an extra layer of safety by stopping the blade quickly after each cut. Its LED work light is a practical feature for improving visibility in low-light environments, enhancing accuracy and reducing mistakes. With a 57-degree bevel capacity, this saw offers versatility for a variety of angled cuts, making it a strong choice for both professional carpenters and serious DIY users.
From the perspective of customers, the DCS590WW1 stands out for its blend of cutting power and safety features. Users appreciate how the electric brake and LED light improve confidence and precision on the job. The robust metal alloy handle provides stability, though the overall weight of 15.27 pounds can be tiring during prolonged use. Another consideration is the higher cost compared to lighter, more basic models. Still, for those who prioritize durability, safety, and cutting accuracy, this DEWALT saw offers a reliable and professional-grade solution that justifies its investment.
FAQs
How to choose a cordless circular saw?
Selecting a cordless circular saw depends on several key factors. First, consider battery voltage and capacity. Higher voltage, such as 18V or 20V, usually means more cutting power. Pair that with at least a 4.0Ah battery for longer runtime. Next, look at blade size—a 6-1/2 inch blade works well for light projects, while a 7-1/4 inch blade handles deeper cuts and tougher jobs.
Don’t forget ergonomics. Lightweight designs reduce fatigue, while rubberized grips improve control. Safety features like electric brakes, blade guards, and dust blowers are also important. Finally, check if the saw is part of a brand’s battery platform, so you can use one battery across multiple tools.
Is it better to have a corded or cordless circular saw?
It depends on your work style. A corded circular saw delivers consistent power and is ideal for heavy-duty use on construction sites where access to power is available. However, it ties you to an outlet and limits mobility.
A cordless circular saw, on the other hand, provides unmatched flexibility. It’s perfect for quick cuts, remote work, or outdoor projects. Modern lithium-ion batteries deliver power nearly equal to corded saws, making them a great choice for most DIYers and many professionals. If portability matters more than nonstop runtime, cordless is the way to go.
Is a 12V circular saw any good?
A 12V circular saw can be useful, but it has limitations. These saws are lightweight, compact, and excellent for quick, small cuts on thin wood or sheet material. They are perfect for home users or hobbyists who need a convenient tool for light-duty tasks.
However, they lack the cutting depth and power required for dense materials or continuous use. If you’re building furniture or working on construction projects, a 12V model will likely feel underpowered. For general versatility, it’s better to start with an 18V or 20V saw.
Is the M12 saw good for professional use?
The Milwaukee M12 circular saw is a reliable tool in the 12V category, known for its compact design and easy handling. For professionals, it can be a handy secondary saw—ideal for cutting trim, sheet goods, or in tight spaces where larger saws won’t fit.
That said, it isn’t meant to replace a full-sized 18V or 20V tool. Professionals needing long runtime, deeper cuts, and higher torque will still prefer higher-voltage saws. In short, the M12 is excellent for specific tasks but not a stand-alone solution for heavy-duty professional work.
Final Thoughts
The best battery powered circular saw strikes the right balance between mobility, power, and convenience. Cordless technology has advanced enough that many models rival corded tools in performance, making them an excellent choice for DIYers and even professionals.
Whether you need a lightweight saw for quick tasks, a powerful 7-1/4 inch model for demanding cuts, or a versatile tool that fits into your battery system, there’s a cordless circular saw that matches your needs. Take the time to compare features, voltage, and ergonomics—and you’ll find a saw that makes every cut easier and more precise.
