Product Overview

WORX WX439 500W 120mm Black and Orange Worxsaw Compact Circular Saw

The WORX WX 439 is classed as a mini circular saw, though worth knowing that its cutting depth of 46mm (1.8")is much larger than standard mini saws which is around 27mm (1").

It still has a compact design (40.7 x 24.6 x 12.4 cm) which you can use one handed. It is powerful enough with the right type of blade to cut tiles, stone, brick, wood, metal and plasterboard with ease.

This saw can also make bevel cuts but please note that a 45 degree cutting angle the cutting depth is reduced to 30mm (1.18")

There is a bevel lever that allows you to change your cutting angle up to 45 degrees instantly.

This saw is an electric saw that you plug into a UK main's socket (Not cordless) For the size of this, the 500W motor is powerful enough to cut through a variety of materials with ease.

Unlike other many other compact saws, this model has a larger cutting depth and you can also cut bevels.

It has been designed for one-handed operation, and I like the quick cutting depth adjustment for easy setting depth settings.

In terms of safety, there is a blade guard which is standard on all power saws and a spindle lock button for easy blade change.

What this mini circular saw can be used for

man using wx439 circular saw to cut a sheet of wood

This saw can be used for cutting wood with a depth of up to 46mm (Almost 2"). With the right blade, it can also be used to cut other materials so it's quite versatile.

I do want to point out though that when I used it that if you force this, like a larger circular saw, it will wander off a straight line. You do have to go slower to allow the blade to cut and clear any sawdust along the way.

Generally though, it can definitely be used with one hand, it's fairly light and it cuts really well.

I cut a few floorboards and decking boards and it did that easily. I also cut some MDF sheets (18mm) and it cut those well, as long as I didn't force the saw.

Who Could Use This?



DIY Enthusiasts

Hobbyists and DIYers looking for a versatile, compact cutting tool for various projects.


Professionals seeking a portable saw for on-site tasks requiring precision and maneuverability.

Home Renovators and Builders

Individuals engaged in home improvement projects, requiring a reliable cutting tool for diverse materials.

I don't usually make a lot of bevel cuts, but I did make a few with this. It works well enough up to about 12mm (0.5"). Anything more than that was a bit of a struggle for me.

In summary, this is a small compact saw that cuts well. You just have to bear in mind it isn't a full sized circular saw with a powerful motor and large blade. If you want to be able to rip large sheets or make long cuts along the grain, you will need a full sized circular saw.

WX439 Comparison to Similar Small Circular Saws

I have included a comparison table just below. I have compared the Makita to a similar WORX and Hychika model of the same blade size. The key difference here is the much larger depth of cut, and the fact that this WX439 can also do bevel cuts. It is more expensive but you are in essence paying for a slightly larger saw with about twice the depth of cutting.

The WORX WX439 is certainly worthwhile considering for general purpose cutting. You can buy these in the UK in Argos and online at websites such as Amazon UK. I have provided a link to Check Availability at Amazon UK. We liked it, most buyers like it and the experts also rate this saw fairly highly.

It is suitable for home use and for those in the trades. When buying this type of saw, concentrate on the cutting depth. If you need up to 46mm (2") then this model is the best choice. If you are cutting smaller depths for floorboards, decking boards, sheets of wood etc, then a smaller model like the WX423 is cheaper and a better option.

If this 439 is not the saw for you, then I suggest looking at our full list of small saw options here. It does however overall get good reviews and I did find it easy to use and that it cut well.
