DEWALT Bare-Tool DC390B 6-1/2-Inch 18-Volt Cordless Circular Saw Review

The DeWalt Bare-Tool DC390B 6-1/2-Inch 18-Volt Cordless Circular Saw is a general purpose product that's ideal for homeowners. Perfect for basic projects around the house, it can handle anything from ripping wood to framing bathrooms with ease. The tool is also a favorite for people who need to create fast cuts or produce finished cuts in tight spaces.

In this review, I'll go over the best features of the 6 1/2-inch cordless circular saw and the types of projects it comes in handy for. I'll also discuss where the tool falls short and other important information you should understand before buying.​

6 1/2-Inch Carbide Tipped Blade

Although this DeWalt saw is sold as a bare tool, it does come with a 6 1/2-inch carbide tipped blade and Allen wrench. The blade features a 45 to 90-degree cutting capacity and will rip through a variety of materials including plywood, maple, birch, pine, and oak. It's important to keep other blades on hand as well to handle different material types. For example, you may want a fine toothed blade if you're going to create finished cuts.

Magnesium Shoe and Upper Guard

For the best durability possible, the DC390B cordless saw is made with a magnesium shoe and upper guard. Most people are used to seeing a steel shoe and upper guard on circular saws, but this lighter material decreases weight while upholding the integrity of the design. Magnesium materials create high-strength tool that make fast rips and cuts possible. The rigid shoe and upper guard also help keep the saw straight when creating long, tough cuts.

Fast Rip Cuts and Cross Cut Capabilities

With 3,700 RPM, the 18-volt circular saw from DeWalt can create fast rip cuts and even cross cuts too. The high RPM deliver maximum power and durability. As a bonus, the cordless saw has a 0 to 50-degree bevel capacity for angled cuts. At 45-degrees, the saw can create 1 5/8" cuts. At 90-degrees, the saw can create 2 1/4" cuts. As a bare tool, the saw doesn't come with a rip fence but it does have the slots for a rip cage incorporated into it.

Fan-Cooled Motor

Thanks to a fan-cooled motor, you won't have to worry about this circular saw overheating, even with extended use. The saw also comes with replaceable brushes that allow you to extend the lifespan of the tool. To prevent downtime, you should consider ordering replaceable brushes when you purchase the saw.

Consumer Ratings

DeWalt has a history of creating power tools that homeowners and professionals can count on. The cordless 18-volt circular saw meets consumers' expectations for excellence and the reviews at various independent review sites show that past purchasers appreciate this tool. That being said, it's important to note that the saw has received some unfair ratings for being a bare tool. The product is advertised as a bare tool so there should be no surprise there. Purchasing the saw as a bare tool should also not be an issue for buyers who already own other 18-volt DeWalt tools.

Summary

When you need a lightweight circular saw to complete light cuts or create finish cuts, you'll appreciate everything the DeWalt Bare-Tool DC390B 6-1/2-inch 18-volt cordless circular saw has to offer. Although the saw offers about half the RPM of a corded saw, the ability to transport it to locations without a power outlet or extension cords is a huge bonus for many DIYers. The battery life's limitations make this a better choice for homeowners than professional contractors. However, it's still a great choice for carpenters on light jobs.
