      Another unique feature of this DEWALT circular saw is that the blade will automatically stop spinning immediately after you release your finger from the power button. This mechanism makes the brakes option obsolete, as every time you need to stop sawing, all you have to do is let go.
    • Blade Choice
      This circular saw uses a 5/8-inch harbor which allows you to use a variety of different blades. This means you can invest in high-quality blades, yielding better results for all of your projects.

Its Flaws

  • Battery Sold Separately

That means that you will have to purchase your own battery and make sure that it fits and works well with the product. Additionally, battery life tends to be limited — if you’re planning to work on a particularly long project, buying multiple batteries is recommended.
