Description

At less than 4 lbs, the WORXSAW is the circ saw to use when you don’t want a big and heavy traditional circular saw to lug around. But despite its slim, compact design, this saw has the functional power of a much larger saw. How is that possible? The arbor on its blade is only ⅜”, half the thickness of blades on full-size saws, so the brushless motor can spin it twice as fast. The one- hand design makes it easy to use. Rip and plunge cuts are pieces of cake. It even makes bevel cuts. Just set the bevel adjustment lever at the degree you need (0-45°). Though, where this saw really shines is slicing up 2” stock lumber. With a depth-of-cut of 1-11/16” it’s the perfect saw for stock lumber projects. The blades are a snap to change with its easy-to-use spindle lock. It features a dust port, so you can attach a vacuum and keep your project clean and visible. Speaking of visibility, its left-sided blade design keeps the tool off the cut-line, which makes for more accurate cuts. And the integrated safety trigger on the handle protects against accidental operation—you need to press two triggers to start up the WORXSAW. This model is a bare tool only. 20V Power Share battery and charger sold separately.

  • Fantastic and works great with same battery from my Worx trimmer
Style: 20V Worxsaw, Batt and Charger sold separ...
[I did not buy the battery, only the saw] If I had not already been using a newer Worx trimmer with the PowerShare battery, I might not have even tried this circular saw - I would have doubted that the battery will last more than a few cuts. But the battery that came with my trimmer has an incredible use and shelf life between charges, I mean really incredible. I can trim my entire back yard every weekend for 3 months between charges. Anyway, back to the circular saw. So I thought why not try the saw and if it uses up the battery so much that I have to charge often, I'll just send it back. Well I'm really impressed. I made a bunch of cuts of 1x4 (easy of course) and then 2x4 and it hardly even brought the battery down a click (the LED status). Nice, clean cuts. The only problem was that there seemed to be something catching as I'm gliding over the board while I'm cutting. And that throws you off the straight line, so that sucks. I turned it over and I could feel a very small bit of metal sticking up, which was the culprit. I just took a very fine metal file and filed it off. No problem at all, and now it glides smooth as silk. All in all, I really like this saw and would recommend it. Especially the battery sharing and battery life. ... show more

  • Terrific
Style: 20V Worxsaw, Batt and Charger sold separ...
Light, maneuverable,and has plenty of power to do the job. Note that this model is the "Nitro" model which has a brushless motor that produces more power. It easily cuts fir 2X4s and plywood. Old (pre 1970 ) 2x4s are thicker than the current standard and it's 1/8" shy of cutting them on one pass. So is every other brand of this style saw, I think. I have used it on some gates and fences. I use the 4 Ah battery and it is still light enough to use with one hand while standing on a ladder. I have even used it inverted. You can do many things easily that you cannot do with other saws. Once you use this saw your jigsaw will be relegated to cutting curves and nothing else. Go ahead and put a top quality blade on it like a Diablo. The tool is a pleasure to work with And it deserves it. ... show more

  • Worx Handy mini Saw .
Style: 20V Worxsaw, Batt and Charger sold separ...
Seems to be a good saw. It bounced off the floor unfazed.😁. Feels balanced with a bigger battery. NO CARRY BAG! Very Disappointed by this.😮💨 Also, no tool to change blades. Around 16" long without battery,or 17"+ with... So you may be able to get this in a 16" bag of the right size. I found several 16" carry bags here...bigger than that They get more like a tool bag. I see people trimming tree branches with this so a belt hook would be nice too. Not sure how to make that happen, looking at it... ... show more

  • Great saw but failed after 6 months of light use.
Style: 20V Worxsaw, Batt and Charger sold separ...
I really liked the saw, but the electric safety brake would kick in unexpectedly while sawing, then finally it kicked in permanently after just a few months of light use, all I get is a flashing LED whenever I try to start the saw - battery is fully charged.
