10 Best Lightweight Circular Saw 2025 in the United States

The DEWALT 20V MAX Circular Saw is a solid option for anyone looking for a lightweight and versatile tool for woodworking projects. Weighing in at just over 7 pounds, it's easy to handle and manipulate, which is great for extended use without too much strain. The 6-1/2-inch carbide-tipped blade is capable of cutting through materials with precision, making it suitable for cutting 2x material at 90 and 45 degrees. Its powerful 5150 RPM motor ensures that even demanding cuts are handled smoothly.

One of the standout features is the 0-50 degree bevel capacity, allowing for a variety of angled cuts, which is particularly useful for more complex projects. The high-strength magnesium shoe contributes to durability while keeping the tool lightweight, an excellent combination for both job-site and home use.

In terms of ergonomics, the rubber overmolded grip helps in maintaining comfort and control during operations, reducing fatigue during longer tasks. Additionally, being a bare tool means that you can use your existing DEWALT 20V batteries, which is a plus if you already own other tools from this line. However, there are some drawbacks to consider. The fact that this is a bare tool means that it does not come with a battery or charger, which could be an additional expense if you don’t already have them. Also, while it excels in cutting wood, it may not be the best choice for harder materials without strain. Finally, some users may find the absence of advanced safety features, like electric brake systems, a bit concerning. For DIY enthusiasts and professional carpenters alike, the DEWALT 20V MAX Circular Saw offers a reliable balance of power, comfort, and versatility. Just be sure to factor in the additional cost for a battery and charger if needed.

The DEWALT FLEXVOLT 60V MAX Circular Saw (DCS578B) is a powerful tool designed for serious woodcutting tasks. Weighing 8.2 pounds, it strikes a balance between being lightweight and sturdy. The 7-1/4-inch blade offers a maximum cutting depth of 2-9/16 inches at a 90-degree angle, which is quite impressive for a cordless saw. It also features a bevel capacity of up to 57 degrees, with stops at 22.5 and 45 degrees, adding versatility for different cutting angles.

The motor power is significant, with up to 5800 RPM, making it faster and more efficient than many other models. The integrated electric brake enhances safety by stopping the blade quickly after the trigger is released. Additionally, the built-in LED light improves visibility and precision, which is great for working in dimly lit areas. However, one downside is that it doesn't come with the battery, which needs to be purchased separately. This could be an inconvenience if you don't already own DEWALT batteries.

The ergonomic design, including a plastic handle, aims to provide comfort during extended use, though some may prefer a more cushioned grip. With a high-speed steel blade and a solid build, it is well-suited for cutting wood efficiently. This saw is ideal for professionals and serious DIY enthusiasts looking for a robust, cordless circular saw with ample power and flexibility.

The DEWALT FLEXVOLT 60V MAX Circular Saw is a powerful cordless option that combines strong motor performance with user-friendly features. Weighing about 10.9 pounds, it’s on the heavier side for a lightweight circular saw but still manageable for most users. The 7-1/4 inch blade is standard, providing a good balance between cutting capacity and portability. Its brushless motor ensures smooth and efficient cuts, with enough power to handle common wood cutting tasks. The saw offers a 2-7/16 inch cutting depth at 90 degrees and a versatile bevel capacity up to 53 degrees, which is quite generous for angled cuts. Ergonomically, the rear handle and left-oriented blade improve the line of sight to the cutting line, helping accuracy. The integrated dust blower and onboard blade wrench storage add convenience on the job. Safety is addressed with an electronic brake that quickly stops the blade after releasing the trigger, reducing risk.

The saw’s weight might be a consideration for those prioritizing ultra-light tools, and the price can be higher due to the included battery and charger. It is well suited for users needing a cordless, durable saw with solid power and cutting flexibility, though those seeking the lightest possible saw might want to compare options.
