Review: With the right blades, this is a honey of a saw. - I really like this saw and rechargeable system. Is it possible to love a saw? I have several tools that use the 20-volt batteries, including the 20-volt rotary hammer and 3 different chargers, as well as the 12-volt vehicle charger so I can recharge the compatible hand-held flashlight and flood light for road emergencies or anywhere I need to see in the dark. I carry them wherever I drive. One never knows. As with any saw, using a sharp blade appropriate for the material one is cutting is always the most important measure to ensure top performance. I have this saw paired with the premium 5Ah & 4Ah batteries and a selection of blades for different materials, some Dewalts and some Diablos (my favorite blades). It fully exceeds my expectations. It will cut all day and then some. It's light and extremely portable, and it tears through solid oak and maple like it's going through soft butter. There is a small "learning curve," as one becomes comfortable with the saw blade on the left side of the tool, as viewed from the operator's perspective. The corded saws I've always used have the blade on the right side, but it doesn't take long to adapt to this configuration. Without a doubt, this saw is my favorite power tool followed by the rotary hammer, which is a close second. The only (small) source of disappointment is that it's shipped without a rip fence. For the life of me, this seems rather cheap behavior on the part of DeWalt, a manufacturer of quality tools that usually doesn't cut corners in my experience. My guess is that it would probably only have cost DeWalt a few extra pennies to have included the rip fence with the tool rather than inconvenience customers with the necessity of purchasing it separately upon discovering this admittedly minor deficiency. The rip fence is available on desertcart for about thirteen dollars as I write, so that issue can be readily addressed. It seems odd, though, and the discovery of the absence of a rip fence in the package might lower the perception of value for some customers. With shipping charges and sales tax, it could easily add $15-20 to the total cost of the saw. Of course, if one does not intend to rip, one might elect to skip it, but that could be short-sighted. From my perspective, one never knows if the rip fence might be needed in the future and there could come a time when it may not be as readily available, so my choice was to make the purchase so as to have it on hand for any contingency. I'm so pleased with this saw that I'm thinking of purchasing the Dewalt 36-volt cordless saw as well. The 36-volt tool uses full-sized 7¼ blades and has even more power than the 20-volt model, thus allowing one to cut thicker material, likely with even greater battery charge longevity, but I digress. To be clear, the reviewed model (20-volt) will meet the needs of the vast majority of those looking for a well-performing portable saw without the encumbrances presented by a cord and its not as heavy as the 36-volt model. I think there's some good news if I decide to purchase the larger model as well in that the rip fence appears to be interchangeable between the two saws, so that assuages the issue from my perspective. Anything I would add would be all good, however it should be obvious that I'm pleased to have made the purchase of this quality DeWalt product.
Review: Good product - Very good saw make sure you get the heavy duty batteries. It cuts well but does go through batteries pretty quickly.

## Questions & Answers

**Q: Will the De Walt  batteries 20V Max lithium ion 1.5 ah and charger i have for my drill set work with this**
A: I bought a 20v Max Li-Ion 3.0 Ah battery for this and got about 32 cuts through some 1 x 6 wood planks before it lost charge.  You could probably get away with 2 of these 3.0 Ah batteries if one is on the charger at all times.

**Q: I have this saw and need to cut a 6ft piece of Caesarstone. Is there a blade that would work with this saw to cut my stone?**
A: It definately will do a good job.  5" mason blade. I wouldn't do it daily if it's your job but a bathroom or 2 is fine.  I've done 5 bathroom jobs and work with wood daily.  Use fhis little guy a lot from ripping siding to decking to studs.  Still works great.  I use a bigger corded worm drive for roofs and tearing into sub floor.  Also 4 of the bathroom jobs were 1/2" rock and 1 was 1/4".  I did probably 30 bathrooms with my 18v.  It was a drag when the nicads would run down.  Hope that helps.

**Q: How do you put the blade on?**
A: The allen wrench is provided in the handle near the battery on the right hand side. Push in the blade lock button at the top of the blade guard to stop the motion. Loosen the bolt with the allen wrench until the clamp is removed. (The bolt is reverse threaded, so it is clockwise to loosen, counterclockwise to tighten, the opposite of most bolts.) Place the blade between the inner and outer washer guards. Pull back the blade guard to insert the blade into place. Use the allen wrench to tighten the bolt into place (using the blade lock button to stop the blade motion). Make sure the blade is securely in place before using.

**Q: Is the blade and cutting line visible from the top when I am cutting the wood.**
A: Yes! ...as long as you're right handed. :)

### ⭐⭐⭐⭐⭐ DEWALT Chainsaw Review: Powerful, Reliable, and Surprisingly Lightweight
*by M***A on May 12, 2025*

I’ve been using the DEWALT chainsaw for a few months now, and it’s exceeded my expectations in every way. Whether you're trimming branches or cutting down small trees, this tool delivers serious power with the reliability you'd expect from DEWALT. One of the best features is how easy it is to use, even for someone who isn’t a professional. It starts up quickly, and the controls are intuitive and well-placed. The chainsaw is also much lighter than I expected, which makes it easy to handle and reduces fatigue during longer jobs. I’m especially impressed with the battery performance (on the cordless model). It holds a charge well and provides enough runtime to get through most jobs without needing to stop and recharge. Maintenance is minimal—chain tensioning is tool-free and straightforward, and the bar oil reservoir is easy to fill. The build quality is solid, and it feels durable and well-balanced in hand. Whether you're a homeowner handling yard work or someone who needs a dependable tool for more frequent use, the DEWALT chainsaw is a great investment.
