REVIEW – Cordless tools have come a long way in the last ten years. I’ve been using mine for quite a bit longer than that, and I’m looking to replace them.

Design and features

If you’ve worked with a corded circular saw, you undoubtedly have found that the cord is quite cumbersome at times. The cord always seems to get in the way at the most inopportune time, usually in the middle of an extended cut.

Not only do cordless tools save you time from running cords, but they also provide a bit of safety on your worksite. I’ve tripped over many extension cords and even ruined a tool or two in the process. I’ll opt to take a few seconds here and there to get a fresh battery rather than deal with extension cords.

WORX advertises the Nitro 20V Power Share Worxsaw as a compact saw. I didn’t really think much of that until I placed it next to my old Craftsman 5.5″ saw. Although the Craftsman uses a slightly larger blade, the WORX Nitro is significantly smaller. The size of the Craftsman has been an issue in the past.

The Worx Nitro on the left, and my old saw on the right.

Utilizing a brushless motor, the Nitro runs 50% longer, is 25% more powerful, and has 10% longer life than a traditional motor. I’m hopeful for this feature, as I have had issues with my grinder motors that utilize brushed motors. The Nitro motor also starts and stops quicker than my old saw.

I found the ergonomic grip very nice, and the safety button is much easier to operate in conjunction with the run switch than my old saw. The safety button was something I did not like on my old saw.

The included Parallel Guide makes it easier to cut a straight line. I did find that the guide was slightly bent, but I was easily able to straighten it out.

The Nitro is designed for stock 2-inch lumber, such as 2×4’s and plywood. The built-in light for the cutline is fantastic and makes working in darker areas much more manageable. Visibility is excellent. The built-in dust port and included vacuum attachment work exceptionally well. Initially, I was not very excited about it, but after using it, I found that it does a fabulous job of collecting almost all of the sawdust.

The dust collection port turned out to be a welcomed feature.
Worx Nitro 9
If you look closely, the left side was cut without the dust collection vacuum, and most of the sawdust on the right was from that cut.

The included carbide-tipped blade cut fast and clean. The blade can be adjusted to cut up to 1.5″ and can cut a bevel up to 46°.

Another item included with the Nitro is a carry bag. The bag is a generous size, having enough space to not only hold the Nitro Worxsaw, but some other items as well.

What I like

  • Compact design
  • Quick start and stop of the motor
  • Built-in light

What I’d change

  • Nothing I can think of

Final thoughts

I found the WORX Nitro 20V Power Share Worxsaw to be a fabulous saw. It’s comfortable to operate, cuts exceptionally well, and is easy to adjust and operate. This was my first Worx product, and I’m sure it probably won’t be my last.

  2. I have this and many other WORX products including :
    * Reciprocating Saw and Jigsaw (brushed only)
    * Brushless 3-Speed Impact Driver
    * Brushless 1/2 Inch Hammer Drill Driver
    * Brushless Leaf blower
    * Lots of 4 Amp Hour and 2 Amp Hour batteries – heavily recommend these

    While I am terrified of using this circular saw as it can cause serious physical harm if used incorrectly, this is a great tool. I have cut down 2x4s and other lumbar using it. I would recommend getting the 4 Ah batteries for this and other devices – not only do they run longer, but they have more torque and power with larger batteries.

  3. for as light as they are this saw tracks surprisingly well

    though i use it primarily for cutting cement products and rock it does a fair job on sheet goods…though i do use a cordless 6 1/2 inch saw for most of my impromptu wood cutting of late

    circular saws have always given me the willies as well…just know where your hands are and set your cut depth to the minimum required and things should be ok

  4. Those that are afraid of a saw, should not own one. Simple. As for Worx, I own several and have beep happy with each and every one.

  5. Thanks for the review. I’m a little confused you said the Nitro is designed for stock 2-inch lumber but later said the blade can be adjusted to cut up to 1.5″. Hope you can help clarify as I’m thinking of buying.
