Regardless of whether you’re building wood decks or dormers, bookcases or kitchen cabinets, the DEWALT DC390B Cordless Circular Saw won’t let you down. This professional-duty saw delivers cordless convenience without sacrificing power or performance. An 18-volt battery (not included) drives the saw’s 6-1/2 in., thin-kerf blade at 3,700 RPM, an optimum speed for crosscutting and ripping construction lumber, softwood, hardwood, plywood, particleboard, oriented-strand board and virtually any other sheet good. With depth-of-cut capacities of 2-1/4 in. at 90-degree, and 1 5/8 in. at 45-degree (bevel), the DC390B can slice through all 2-by dimensional lumber. Other professional features include: durable fan-cooled motor with replaceable brushes, magnesium shoe and upper blade guard for high strength and lightweight, vibration-dampening rubber-grip handle, and a 50-degree bevel-cutting capacity. The compact saw comes with a carbide-tipped saw blade and blade wrench. It’s backed by DEWALT’s 90-day money-back guarantee, full one-year service contract, and three-year limited warranty. Battery and charger sold separately.

Rated 4.8 out of 5 by 21 reviewers.
Rated 5.0 out of 5.0 by Quality Product I purchased this product because of price and it didn't come with a battery. I have numerous dewalt batteries and they interchange with this product perfectly. October 7, 2014
Rated 5.0 out of 5.0 by Great Good power, good craftsmanship. Should include rip fence, but doesn't. Overall great tool. October 15, 2014
Rated 5.0 out of 5.0 by Great Saw We got this saw for small DIY projects around the house and so far it has worked great. No issues and the battery life has been better than I first thought it would be. It is also much lighter than my old saw which means my wife can even use it. September 24, 2013
Rated 5.0 out of 5.0 by Nice Saw I really enjoy this saw. The battery last long enough to suit my needs on most projects. Not having a cord to deal with saves time and I can concentrate on the cut without worrying where the cord is. The saw is well balanced and feels comfortable while making cuts. The manual is vey thorough and informative. I like the fact that the saw comes with an allen wrench attached to change the blade, no searching for the right tools to make changes. Delivery of the product was very fast. January 22, 2011
Rated 5.0 out of 5.0 by This product has power like a wired saw Highly recommend for DIY people. Handy, no wires to deal with, plenty of cutting power, uses all the old DeWalt 18V batteries you use for your other tools May 22, 2012
