Comparison

The DeWalt DCS391B is a brushed motor circular saw, while the DeWalt DCS565B and Makita XFD07Z are brushless motor circular saws. Brushless motors are more efficient and powerful than brushed motors, so they can provide longer runtime and faster cutting speeds.

The DCS565B also has a few features that the DCS391B does not, including a rafter hook, a dust port, and a LED light. The rafter hook allows you to hang the saw from a rafter, which is helpful when working overhead. The dust port helps to keep your work area clean, and the LED light provides better visibility when cutting in dark areas.

The Makita XFD07Z is another brushless motor circular saw that is similar to the DCS565B. It has the same features as the DCS565B, but it is slightly heavier.

Conclusion

The DeWalt DCS391B is a good value for the price. It is a powerful and versatile circular saw that is well-suited for a variety of tasks. However, if you are looking for the best possible performance, the DeWalt DCS565B or Makita XFD07Z are better options. They are both more expensive, but they offer longer runtime, faster cutting speeds, and more features.

Which one should you buy?

The best circular saw for you will depend on your needs and budget. If you are looking for a good value and don't need the latest features, the DeWalt DCS391B is a great option. If you want the best possible performance and are willing to pay a bit more, the DeWalt DCS565B or Makita XFD07Z are the better choices.

• Risk of electric shock. Do not expose to rain or moisture.

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication.
