Worx 20V Cordless 4 1/2-Inch Circular Saw Gets A Refresh
The Worx Nitro 20V cordless 4 1/2-inch circular saw originally came on our radar in the back half of 2021, and the DIY-targeted compact saw is already getting an update.
Worx Nitro 20V Cordless 4-1/2-Inch Circular Saw Updates
The Worx WX531L now has updated circuitry engineered to change its power depending on the material youโre cutting. Its power under load increases up to 55% on hardwoods like oak and maple, and readjusts for lower power when youโre cutting into softer woods like pine or OSB. Worx designed this technology to conserve runtime and increase the longevity of your batteryโs life.
Another important change to this saw is actually to the blade itselfโ it comes with a 4-1/2-inch carbide-tipped CuttingEdge blade featuring 24 teeth. According to Worx, this type of blade is more appropriate for carpentry work, so you get higher-quality cuts that produce a better finish.
The bladeโs thin kerf design achieves no-load speeds of up to 6,900 RPM. Thanks to its brushless motor, the Worx Nitro 4 1/2-inch circular saw gets up to 25% more power and 50% longer runtimes compared to similar tools that used brushed technology.
Worx Nitro 20V Cordless 4 1/2-Inch Circular Saw Design
The physical design of this saw follows models such as DeWaltโs 20V Atomic 4 1/2-inch circular saw and is meant to use with one hand. Its lighter weight is easier to manage, though it does take some practice to cut accurately.
The saw has a maximum cutting depth of 1-1/2 inches at 90ยฐ and 1 1/8 inches at 45ยฐ. Its beveling capability ranges from 0ยฐ to 46ยฐ. At 90ยฐ, thatโs just enough to cut through 2x material, but cutting sheet goods is what saws like the WX531 excel at.
Particularly if youโre right-handed, you have a fantastic sight line to the blade since you donโt have a second hand obstructing your view.
Additional Features

- Ergonomic handle
- Spindle lock for fast blade changes
- Lightweight and compactโ weighs less than 5 lbs with battery
