They say a handyman is only as handy as his tools, which is why dedicated woodworking hobbyists and aspiring professionals should settle for only the best power tools they can find.

Every good woodworker needs a quality circular saw in their arsenal, the kind that can only be purchased from a reputable brand with a history of excellence.

DEWALT is one such brand and its DCS391B is certainly a quality circular saw. We are going to be looking at the saw and all that amateurs and professionals have to gain from purchasing it in this article.

The DEWALT DCS391B is perfect for use in the workshop and can also be utilized on a worksite, where it just isn’t feasible to install a table saw to cut materials. With its lightweight design and ergonomic grip, it can be used for hours on end without putting any strain on the arms or back, making it the ideal tool for large projects and tight deadlines.

Since first introducing the world to the DCS391B, DEWALT has released the DCS570B, which boasts many of the same features as its predecessor, but is fine-tuned for professional use, which, as you likely guessed, gives it a higher price tag.

Who is this Product for?

The DEWALT DCS391B is intended for both personal and professional use, but it generally sells for close to $100, which means only the most dedicated hobbyists should consider purchasing it. 

When it comes to light to medium jobs, this circular saw is a perfectly acceptable replacement for a table saw, so DIYers who don’t have the room needed to install a table saw should give the DCS391B careful consideration.

However, professionals will not be able to base their entire company on this product – or any circular saw, for that matter – and so should purchase it only to have a secondary saw that they can turn to when their table saw cannot be used.

Whats Included?

he DEWALT DCS391B is absolutely loaded with features, which we will take a look at in just a little bit, but if you like a tool that comes packaged with additional accessories to enhance the using experience, you should take your search for the best circular saw elsewhere.

When you buy the DCS391B, you’re buying the tool itself and will not receive any of the add-ons you would normally get with a power tool purchase. DEWALT doesn’t even include the battery necessary to power the DCS391B, so you’ll have to purchase it separately, which will push the total cost of this saw beyond the $100 mark.

Overview of features

Despite its lack of additional accessories, the DEWALT DCS391B boasts some pretty impressive integrated features. For example, this saw runs on a motor that provides 5,150 RPM and comes equipped with a high strength magnesium shoe, which makes for greater durability and accuracy even in heavy-duty professional environments.
The DCS391B features a blade of almost 7 inches, which promises a cutting depth of close to 3 inches and a bevel capacity of 50 degrees, which means the tool can be used to complete a number of tasks commonly assigned to table saws.


Whether you’re a woodworking novice or a seasoned professional, you should never use a power tool unless you know exactly how to operate it. Failure to familiarize yourself with the workings of each specific tool in your arsenal could lead to disaster, which is why we recommend watching the below video in which you will see the DEWALT DCS391B in action.


If you’re a hobbyist and don’t have the workload to justify spending $100 on the DEWALT DCS391B, we recommend going with a less expensive circular saw, such as the PES01A from Tacklife.

The Tacklife PES01A features a motor capable of 4,500 RPM, which is ideal for hobbyists, and is fitted with two 7 ¼ inch blades for greater versatility and accuracy in cutting. The tool generally sells for just a little over $50, which means it is almost half the price of its more expensive DEWALT alternative.


So, what is our final verdict on the DEWALT DCS391B? At the risk of being accused of being DEWALT fanboys, we think this circular saw is awesome! With its powerful motor and near 8-inch razor-sharp blade, it blurs the line between hobbyist and professional and will take any DIYer to the next level.We do, of course, have to condemn DEWALT for not including basic accessories with this saw, but the brand must be commended for the impeccable design of the drill itself and the attention given to the design of its integrated features. Once you secure the battery to power the DCS391B, there will be nothing to stop you from attaining wooden perfection, be it in your personal garage or on the worksite.
