DeWALT Cordless Circular Saw: The DC390K

Though a corded circular saw can give more prolonged power, having one which is cordless allows it to be taken anywhere a cut needs to be made – no need to bring the material to the saw, the saw goes to the material.

Among manufacturers of such tools, DeWALT is a leader and an impressive innovator. So, looking closely at the DeWALT DC390K 18V cordless circular saw is a very good idea and a great place to start.

DeWALT’s DC390K 18V cordless circular saw makes use of a standard (for this class) 6.5 inch circular blade and is powered by an 18-volt XRP extended life nickel-cadmium rechargeable battery.dewalt cordless circular saw

This gives the motor the power to turn the unladen blade up to 3700 RPM to allow for quick rip and cross cuts.

That motor also is fan-cooled and has replaceable brushes so that the saw can always be refurbished and put back in action as if new.

It is fitted with a high-strength and lightweight magnesium shoe and upper blade guard for added durability without the extra weight.

Standard bevel capacity applies – 0 to 50º – and it will lock at 45º and 90º, where the saw can deal with 1.625 inches and 2.25 inches respectively, allowing for a broad set of capabilities.

All of this comes together into the single DeWALT DC390K cordless saw and it weighs in at 8.7 pounds (3.95 kg), a small price to pay for the flexibility offered by this tool.


DeWALT has created a very useful piece of equipment in the DC390K; it’s flexible, competent, and easy to move from job to job when none of them are close together.dewalt dc390k circular saw review

The 6.5 inch kerf blade shipped with the tool is a 16-tooth, carbide-tipped, and is said to give twice the cutting capacity of competitors’ offerings; it certainly performs very well for a stock blade.

This is a professional-level saw and will perform for anyone as well as it would for those who use it in their day job; it is reliable, well-built and very good at what it does.

The DeWALT DC390K can easily find a home in anyone’s tool kit and it will likely be there until it is handed down to the next generation.

The DeWALT DC390K 18V cordless circular saw can be found at a suggested retail of $377, but it will be easier to find one for under $200 just about anywhere tools are sold.
