How to Choose the Best DEWALT 20V Circular Saw

When shopping for the DEWALT 20V circular saw, it is important to be aware of what goes to the best model that will serve your needs for longer. In this section, we discuss features that you can consider so that you get the ideal 20V circular saw for your woodworking needs.

  • Power

This is an important feature to consider in the saw you intend to buy. Unfortunately, most manufacturers never publish all the data on their circular saws. When checking the power of the circular saw, don’t forget to check the blade speed. A good 20V circular saw comes with between 4,000 to 6,000 rpm range. Also, look at the torque, it should be significantly high than a sidewinder.

  • Batteries

Battery power is measured in volts and the DEWALT 20V circular saw will certainly come with a 20V battery pack. However, there are two types of batteries that are often used in circular saws. Some models may come with Nickel Cadmium (NiCd), but this type of battery is made from an old technology that contains an environmentally unfriendly cadmium.

On the other hand, some may come with a Lithium-Ion (Li-Ion) battery model. Of the two models, the Lithium-Ion battery is far better as it provides more power, longer run time and lighter compared to NiCd batteries.

  • Charging Time

Certainly, nothing is frustrating as putting a hold to your project because of your battery requires more time to charge.  When buying the DEWALT 20V circular saw it is recommendable to buy another battery packs so that when the other pack is in use, the other one is charging. Charging time varies but most batteries feature a 30 to 90-minute range.

  • Blade Right or Blade Left

The side on which the blade is on can also determine how best you can operate the saw. Are you left-handed or right-handed? The answer to this question will determine the saw you will buy.

However, a blade on the left saw is said to be more flexible when it comes to making cuts as it allows you to see the cut line more clearly than when on the right side. So, try to use both models before you buy so that you can see which one you can work best with.

  • Electric Brake and Blade Guard

An electric brake is a great safety feature that few models come with. This type of braking system reverses the current in the saw thereby stopping the blade once the trigger is released. Besides, ensure that your 20V circular saw is equipped with a retractable blade guard that covers the blade whenever the blade is not engaged. As such, after cutting you can set the saw guard down even before the blade comes to a complete stop.

How to Safely Use the Circular Saw

Before you start using the circular saw, make sure that you have taken all the safety measures. Start by wearing an eye protector when operating the circular saw. You must make sure that the blade you select is suitable for the job at hand and that it is firmly attached to the saw unit using the arbor nut.

Adjust the sole-plate to the appropriate height and bevel for the job. When ready, firmly holding the handle and align the blade near the line you intend to cut through. Press the safety switch before pushing the trigger switch. Slowly and carefully follow the cut line to cut the material with precision it requires.

Towards the end of the cut, ensure the material is held and won’t splinter due to the unsupported weight. Caution! Bear in mind that the teeth are very sharp and should not be carelessly placed on surfaces that could easily damage.


If you are looking forward to cutting wood or other materials in your workshop or at your job site, the DEWALT 20V Circular Saw is the best option to get you started as it comes with high power, high-performance, great safety features, long-lasting battery and durable construction all at an affordable price.
