The Differences Between DCS393 vs DCS391


The most noticeable difference between these two circular saws is their foot.

Dewalt DCS391


DCS391 is well-known for its powerful motor, which meets the demand of a faster working environment on your preference.

This motor will take you by surprise when you give it a spin.

With the ratings of 460 MWO and 5250 RPM, it allows you to make perfect cuts, even a beveled one.

Magnesium shoe

Although the shoe is lightweight and comes at a small size, it can provide users with high strength and great power.

Moreover, thanks to this feature, DCS391 ensures users a comfortable working environment with long-term accuracy and durability.

Bevel capacity

From 0 to 50 degrees, you are free to make any aggressive bevel cut with great control and accuracy on all materials.

One special thing about DCS391 is that the degree is clearly marked, enabling you to adjust the desired angles with ease and comfort.

Besides, to adjust the depth of the cut, you need to unlock the lever and change the base shoe on your preference.

Over-molded rubber

Compared to DCS393 which features metal rubbers, DCS391 is designed with alloy mold rubber.

This rubber allows you to preserve balance and control on any large-scale project, and receive perfect products with ease and comfort.

Carbide-tipped blade

Like most circular saws with such a compact design, DCS391’s blade is 6.5 inches, enabling you to cut twice at 45 and 90 degrees at every charge.

However, be careful when making different cutting angles, as this blade may not be always cutting straight.


  • Lightweight and durable
  • Powerful and smooth cut
  • Great balance and control
  • Value for money
  • High strength and accuracy


  • The battery may be annoying

Who Should Choose DCS391?

Frequently Asked Questions

Why does my circular saw pull to one side?

After years of operating, the circular saw is likely to pull to the left or the right if not regularly checked, resulting in an unsafe and ineffective working environment.

Therefore, check and tighten the base plate to make the blade remain balanced.

Why does my circular saw not cut straight?

We bet that seeing your saw not cutting straight drives you crazy!

So firstly, let’s have a look at your piecework and make sure that it lies stably and doesn’t move when your saw is cutting.

Another possible reason lies in your saw blade, which should be stable for a perfectly straight cut.

After operating for a long time, the holding nut may be loosened, thus cannot carry the saw properly.

If this is your problem, quickly tighten the nut until it is snug.

How tight should a circular saw blade be?

It is highly recommended that the blade should be tightened as much as possible, as the tighter the blade is, the more powerfully and safely the saw operates.

To tighten the blade, you should see a bolt attaching near the blade.

Then, use a wrench and tighten the bolt clockwise if you are right-handed, and counterclockwise if you are a left-hander.

However, remember not to over tighten it; it will be challenging for you to unplug and exchange the blade later on.
