An 18-volt battery (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.

DC390K 18-Volt 6-1/2-Inch Cordless Circular Saw
At a Glance: 3,700 RPM for fast rip cuts and cross cuts

Includes carbide-tipped blade

Includes one battery and 1-hour charger

Three-year limited warranty; one-year free service

Power and Performance

With depth-of-cut capacities of 2-1/4-inch at 90-degrees and 1-5/8-inch at 45-degree (bevel), the DC390K 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.

DEWALT's XRP Extended-Life Battery System

A tool's only useful if it runs long enough to get the job done, and the DEWALT XRP extended run time batteries keep the DC390K running at full tilt. They provide up to 40 percent more run time than standard Ni-Cad batteries, and any XRP battery can be used with any 18-volt DEWALT tool, which allows you to expand your system by adding other DEWALT cordless tools (sold separately) as the demands of your job grow.

The DC390K comes with one 18-volt XRP battery and a 1-hour charger.

Warranty

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.

What's in the Box

DEWALT DC390K 18-volt 6-1/2-inch cordless circular saw; carbide tipped blade; blade wrench; operating instructions (batteries and charger included)

0-50 degree bevel capacity provides additional capacity for a multitude of applications (view larger).

One Fine Piece of Craftmenship

 on June 12, 2017
By Tony
I purchased this saw about two weeks ago. It arrived in about two day, well packed and undamaged. After charging the battery I began working on my deck. This saw cut through pressure treated lumber like butter. While cutting there were a time or two I got slightly outside the line and had to readjust the blade. The saw worked perfectly, the adjustment didn’t slow performance. It was perfect in every way. This is an excellent product.

Great addition for many reasons.

Solid and reliable. It doesn’t have the power to work for extensive projects, but is exceptionally handy. I use it to routinely cut lumber to size, with accurate follow-up cuts on the table saw.

good cordless saw

 on September 18, 2013
By DG
I have had a few 12 volt Dewalt circular saws and the older 18 volt Dewalt and the as well as several Makita cordless circular saws including the new Makita 18 volt lithium ion saw – and I have worn out a few of them- but the most powerful one I have used is this new Dewalt saw and the batteries seem to last longer. I like the Makita for it’s weight and it is more comfortable to use but power is the main thing and new Dewalt wins in this category. This saw has a safety lever that seems hard to push while holding the trigger and the battery mount is made for their new lithuim 18 volt- but the old ni-cads work fine in it. It is maybe the best choice out there right now.

Good portable saw

I’ve only done light work with it, but so far it shows all the signs of working as well as most DeWalt gear. Only one battery, but I already have two other 18v DeWalt tools, so that doesn’t really make a difference to me. Yes, it would be nice to have a more substantial blade guard and it wouldn’t have added much to the price.

I bought this for my husband as a Christmas present. He said it’s perfect; just what he wanted.

Great tool!

I love this tool! Works great! I don’t use my corded circle saw anymore unless I run out of battery power with this one, which is rarely. Vendor was terrific! Arrived on time. Price was right. I have many Dewalt tools, and this one is as good as the others I own. Note that the charger for this tool will charge 12v as well as 18v

Good value for a Dewalt Circular Saw

 on September 26, 2011
By Bill H
I needed a new battery and charger for my Dewalt drill and figured I could use a saw too. Found this re-conditioned Saw with charger and battery at a price that was not much more than that I would have paid for a charger and battery alone. Delivery was quick and equipment works great. Thanks Amazon!

renovations made easy

bought for doing a renovation requiring mods to framing in a house and this made it a cinch to cut 2x4s, etc without dealing with cords.. especially when the power in the house is switched off

He loves it
