10 Best Lightweight Circular Saws 2025 in the United States

The DEWALT 20V MAX Circular Saw (DCS391B) stands out in the lightweight circular saw category thanks to its powerful 5150 RPM motor, which ensures efficient and smooth cutting through wood. Weighing in at 6.95 pounds, it is relatively lightweight, making it easier to handle during prolonged use.

The 6-1/2 inch blade size is versatile for most cutting tasks, and the high-speed steel blade ensures durability and precision. Its 460 MWO motor delivers plenty of power for demanding cuts, while the 0-50 degree bevel capacity allows for a range of bevel cuts suitable for various applications. The magnesium shoe adds to its durability and accuracy on the job site, while the rubber overmolded grip offers comfort and control, reducing user fatigue.

This model does not include batteries, so users will need to purchase them separately, which could be seen as a downside. Additionally, it features a keyless blade change, which simplifies blade replacements, enhancing its user-friendliness. This circular saw is ideal for DIY enthusiasts and professionals who need a reliable, lightweight, and powerful tool for woodworking tasks.

The DEWALT ATOMIC 20V MAX Circular Saw is a compact and lightweight tool, weighing just 5.5 pounds, making it easy to handle for tasks requiring mobility or extended use. Its 4-1/2-inch blade is smaller than typical circular saw blades, which means it won’t cut very deep—ideal for thinner materials like plywood or trim but less suited for thick lumber. The brushless motor provides efficient power and longer battery life, although the saw is sold without a battery. It can cut as much as 369 linear feet on a 3/4 inch board with the appropriate battery, which is good for its size.

The saw offers a bevel capability up to 45 degrees, allowing for angled cuts on thinner wood, which adds versatility. Ergonomics are well considered with a removable auxiliary handle for better control and a 1-1/2 inch trigger designed to comfortably accommodate different grip styles. Safety is addressed with an electronic blade brake that quickly stops the blade after release, reducing risk during use. Additional features like onboard blade key storage and a dust port make blade changes and cleanup easier.

Due to its smaller blade, this saw is best suited for light to medium woodworking projects rather than heavy-duty framing or cutting thick materials. It is ideal for DIY enthusiasts or professionals who need a portable saw for precision cuts and convenience rather than maximum cutting depth.
