Differences Between Dewalt DCS391 Vs DCS570

This time, you will have a more detailed look into these differentiating factors.

Accuracy

Highly visible scales on both models make operating with either of these circular saws a lot more accurate. 

However, what makes the DCS570 stand out is its electric brake. This feature generates quick stops and greatly enhances the precision of your cuts. For this reason, it wins the first point.

Design & Material

Both circular saw models have slick, modern designs that come in shades of yellow, black, and grey. The two are  compact. The DCS570 model’s dimensions are 11 x 8 x 10 inches, and DCS391 measures at 8.5 x 15.5 x 10.5 inches. They are also cordless, making it very convenient to use. 

However, the stable and lightweight magnesium shoe for greater durability and accuracy combined with the light and compact design of the DCS391 provide it with unmatched maneuverability. So this model wins this round.

Motor

The DCS391’s brushless motor delivers a decent speed of 5150 RPM and 460W power that will make the most demanding cuts with ease, but it still falls slightly behind DCS570. This model’s motor can generate a speed of 5200 RPM and a wattage of 900W, making it the better in terms of motor. 

It can provide powerful cuts. Dewalt brushless motor technology can deliver excellent performance and runtime when cross-cutting 2 tough materials and ripping sheet goods.

Saw Blade

The DCS570 cordless tool blade’s diameter measures at 7-1/4 inches compared with the 6-½-inch carbide-tipped blade of the average-sized blade of the DCS391 model. The over-7-inch electronic blade can offer amazing cuts on the edge of the blade plus very smooth control. 

Therefore, this point again goes to DCS570.

Capacity

The 7-1/4-inch carbide tipped blade of the compact DCS570 circular saw has incredible depth bevel capacity. Cutting as deep as 2-9/16 inches at 90 degrees and around 2-1/4 inches deep at 45 degrees, this model can handle almost all types of material. 

Plus, a bevel angle of 57 degrees greatly enhances the versatility of the DCS570.

Meanwhile, the cutting capacity of the DCS391 model is 2-⅛ inches at 90 degrees and 1-⅝ inches at 45 degrees. The versatility offered is in the range of 0 to 50-degree bevel capacity. 

So, it goes without saying that the Dewalt DCS570 takes the lead over its counterpart when it comes to the cutting technique.

Miter Gauge

Both the DCS570 and the DCS391 have onboard miter gauges. The miter gauge helps to secure the wood at a set angle, drastically increasing the precision of the ideal tool. 

Combine this accuracy with the models’ power and efficiency, and you will have powerful and useful tools. However, this miter gauge is almost the same in both models, so it is a tie for this feature.

Extra Features

Only the Dewalt DCS570 comes with mechanical blade brakes. This helps the tool stop the operating blade after trigger quickly, about 2 or 3 seconds. This feature is immensely beneficial as it can improve the performance and ensure safety for the operators.

Again, DCS570 gets one more point.

Safety

Operating with any tool, concern for safety should always be the priority. And for the inclusion of the electric blade brake, the DCS570 comes out on top regarding safety. 

Included Tools

The DCS391 model comes with a ⅝-inch arbor, while the DCS570 model includes an excellent blade changing wrench for obvious maintenance purposes. Both of the Dewalt circular saws require Lithium Ion batteries with great battery capacity, but they don’t have batteries included.

I will not give any point for both since they don’t come with any exceptional included components.
