Whether building wood decks or dormers, bookcases or kitchen cabinets, the professional-duty DEWALT DC390B 18-volt, 6-1/2-inch cordless circular saw delivers cordless convenience without sacrificing power or performance. An 18-volt battery (not included) drives the saw's 6-1/2-inch, 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.

With depth-of-cut capacities of 2-1/4-inch at 90-degrees and 1-5/8-inch at 45-degree (bevel), the DC390B can slice through all 2-by dimensional lumber. The 6-1/2-inch carbide tipped blade gives you 2x cutting capacity at 90 and 45 degrees, and the 0-50-dgree bevel capacity provides additional capacity for a multitude of applications.
A high strength magnesium shoe and upper guard provides increased durability, while a fan-cooled motor with replaceable brushes provides maximum power and durability. It's complemented by a vibration-dampening rubber-grip handle for comfortable handling on big jobs. This circular saw weighs 6.3 pounds.
This DEWALT cordless tool does not come with a battery or charger. It's compatible with the DC9096 18-volt XRP battery pack and DW9117 15-minute charger.
This DEWALT tool is backed by three-year limited warranty covering any defects due to faulty materials or workmanship (from the date of purchase). It's also covered by DEWALT's one-year free service contract, where DEWALT will maintain the tool and replace worn parts caused by normal use--for free.
One DEWALT DC390B 18-volt 6-1/2-inch cordless circular saw, one carbide tipped blade, one blade wrench, and operating instructions (batteries and charger sold separately).

This is one almighty little saw !!!,
By PLEASE NOTE: this saw has recieved some undue bad ratings because it is a BARE TOOL (a perfect replacement or addition to your existing 18v DeWalt tool collection) It does not come with a battery or charger ... well duh! A single battery retails for over $80 alone, what do you expect? It does however come with a blade (nice little suprise to me). This is a great buy and I'm sure you will be very pleased with it's capabilities if you purchase one.

Good saw- if you need the battery & charger - buy the kit,
Amazon Verified Purchase(What's this?)
This saw got poor reviews due it being the saw only- which is great for those of us who have other dewalt tools and all ready have batteries. Otherwise it is a fine saw for use when pulling out a corded saw is too much work or your not near electricity. It's not a replacement for a corded tool- but it has worked very well for me when cutting conduit, some 2X4's and working on the fenceline without electricity.

3 years and counting....,
By jg (OLNEY, MD United States) - See all my reviews Apparently i was wrong. I am a handyman/carpenter by trade and have used this thing to rip 1x and plywood, crosscut 2x anything...and it takes it. I keep 3 different blades and always try to use the appropriate one for the material i am cutting and of course, a fully charged battery. The last framing job i did, i used this thing to cut over 250 2x4's for the walls. The corded Makita sat unused for two days. For all the criticism of this saw, it does the job for me...for 3 years now of daily and sometimes abusive use. But, as always, the Dewalt batteries suck so i keep 3-4 charged all day.
