DEWALT DCS391N-XJ XR 165 mm Circular Saw-Bare Unit, 9 W, 18 V, Yellow/Black

Product Information

I’ve got a love/hate relationship going with the bevel adjustment on this saw. I’m a huge fan of the fact that it marks out each degree from 0 – 50°. That’s brilliant for when you need to make an odd bevel cut. It’s But what I really don’t like that when you loosen off the fastener, it drops all the way to 50° rather than 45°. It’s good that you can get up to 50°, but you’re much more likely to need a 45° bevel. You need to stop and line it up each time, there isn’t a detent that helps you catch the common bevel angles you might need like 22.5°either. The DeWalt DSC391N Circular saw is supplied body only. A 165mm blade combined with 3700rpm powerful motor means this 18v cordless circular saw will make light work of any cutting job. Ultra thin kerf 165mm 24tooth carbide tipped blade allowing for efficient run time and fast, smooth cut finish allowing 55mm depth of cut

They certainly know a thing or two about making a comfortable handle. The rubberised overmoulded grip stretches from the bottom of the trigger grip and envelops the entire “T-shaped” front grip as well. It’s a cinch to hang on to, even without my trusty nitrile coated work gloves on. Unboxing this DeWalt DCS391 Circular Saw was quite underwhelming. In comparison with the bright and informative boxes that the Makita or Bosch saws came in, this was a bit disappointing. I know this is sold as a “bare” tool, but a plain cardboard box is as bare as they come!

When plugged into a dust extractor hose, there’s barely enough room left for your hand on the handle! I’m surprised at this design decision as it’s not very user friendly or well thought out. And if you’re a left handed user, it’s virtually impossible.

The rip cuts I made into some softwood board were surprisingly easy. I didn’t expect this performance from a lightweight battery operated saw. The guide rail is marked with measurements and feels solid enough when clamped down as well. It leaves a nice thin kerf and was easy to push through the timber. DeWalt have gone down the premium route when it comes to the baseplate. It’s made from cast magnesium, which is light as well as incredibly tough. Magnesium shoes are usually the most expensive option on a circular saw, as it’s lighter than steel and more durable than aluminium.

The blade that comes with this saw is the DT1209. It’s designed to work specifically with the DCS391 and is optimised for cross cutting. But rip cuts (where you cut along the grain of the wood) are a big part of any challenge, so I also set the saw up to cut along the length of constructional timber using a fence. Circular saws are wonderfully versatile tools, especially when you cut the cables and go cordless. The ideal job for any circular saw is making cross cuts in constructional timber, so I started testing with CLS that measured 37 x 135 mm.
