Today I get to mess with a new saw! I’ve used standard 7 1/4” circular saws for a long time, so it’s pretty awesome that I finally get to try out a 4 1/2” version. As an electrician, I think this may be a better tool to have on a job site than a large circular saw so let’s get into it.

First Impression

This thing looks badass right out of the package. It is a part of the new ATOMIC line of tools that DeWalt is pushing this year. For those who do not know, DeWalt has a line of XR tools that are 20-volts and normal-sized. XR is their pro-grade selection of tools, similar to Milwaukee’s FUEL line. So ATOMIC is a more compact version of their XR tools. They offer nearly the same power (not in all cases), but a smaller size, similar to how Milwaukee has an M18 (full-size) and M12 (compact) version of their tools. XR is full size, ATOMIC is compact.


So how does the saw actually perform? I tried it on cutting scabs for shimming out receptacles using 2×4’s and this little saw ripped through them with no issues. I used a 2ah 20v lithium-ion battery to cut with, and found it ripped through the material just fine. I put in a 60v FlexVolt battery and got 6ah of 20v battery power out of it as well, which I was able to cut with for the entire day.

I like that there’s a hanging-hook on the base of the handle, so you can hang it from a ladder or a tool belt temporarily between cuts. You wouldn’t carry this around on your belt all day, but since you can use it with one hand it’s helpful to be able to hang it and keep it near by wherever you are.

Electricians don’t often need a full-sized circular saw, more often than not we’re either cutting sheetrock or studs, so this little saw does a great job of dealing with small cuts like this. The fact that it is cordless and brushless makes it able to compete highly with anything else on the market currently. One thing I noticed that’s different than normal circ saws is the way you change out blades. Normally you need a small hex-wrench to remove the 7 1/4” blades, but with this little guy all you need is an Allen wrench. I don’t see a benefit or disadvantage to this either way, as both full-sized and compact versions of their saws have a slot that the tool snaps into, so you don’t lose the tool.

I’m a big fan of this ATOMIC saw. It’s going to replace my full-size circ saw in my truck, since I don’t have a true need for something that large on electrical jobs. It’s definitely powerful enough for me to use on any job I currently need it for, and the compact size makes it a plus for stowing in my work truck. 5 out of 5 stars in my opinion.
