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 ATOMIC 20V MAX Circular Saw (DCS571B) stands out as a lightweight and compact option, weighing only 6.6 pounds. It uses a 4-1/2-inch high-speed steel blade, which is smaller than standard circular saw blades, potentially limiting its cutting capacity but making it more maneuverable for lighter tasks. The tool is powered by a brushless motor, which provides efficient performance and can cut up to 369 linear feet of 3/4 inch OSB on a single charge with a DCB205 battery (sold separately).

The saw's cutting depth and bevel capacity are quite versatile, with the ability to cut through 2x material at 90 degrees and bevel cuts at 45 degrees, ideal for various wood projects. Ergonomics are well-considered with a removable auxiliary handle for better control and an easy-to-use 1-1/2 inch finger trigger. Safety is also a priority, featuring an electronic blade brake that stops the blade quickly, reducing the risk of accidents. Additional conveniences include a hang hook for storage, on-board blade key storage, and a dust port to help manage sawdust.

However, a notable drawback is that the battery and charger are not included, which means additional costs for users. Also, the smaller blade size may not be suitable for heavy-duty tasks. Best suited for DIY enthusiasts and professionals looking for a portable, efficient saw for light to medium-duty wood cutting tasks.
