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 out of 5 by Great Good power, good craftsmanship. Should include rip fence, but doesn't. Overall great tool. October 15, 2014
Rated 5 out of 5 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 out of 5 by Excellent tool This is an excellent tool, and an excellent buy. Nice addition to my other 18v DeWalt cordless tools. I'm especially pleased that DeWalt has designed these tools to use Lithium batteries in addition to NiCad's (which came with my original 18v tools). August 26, 2014
Rated 4 out of 5 by Great addition to my tool-kit Great tool. Easy to use. Interesting feature is that the sawblade is on the Left-hand side of the tool, rather than the right side for most conventional corded saws. Only complaint was that the saw came WITHOUT a rip fence........... I knew the battery was not included but I was astounded by the lack of the rip fence(which, I understand is availabe for sale separately. I called DeWalt Customer Service and complained bitterly. The customer service agent was so sympathetic with my bleating that he arranged to send me a rip fence, gratis!. As as result, I am now satisfied! November 29, 2011
Rated 5 out of 5 by great cordless saw sorry for mixing the blade review with the saw review. the saw is very good - pro quality and the blade makes it even better. cut thru almost any thing and smoothly January 15, 2014
