    • Incredibly versatile small saw
Review Image by Robert G
Review Image by Robert G
I love this saw . It's not that heavy, because of size its very versatile and quite hardly any noise to it with alot of power and torque for a battery operated saw. Feels very durable. Worst part about it.... is the Allen wrench they give you to change blade. It doesnt stay put, you will lose it because it keeps falling off and barely snaps into place. Easy to install blade and saw dust is thrown though moveable chute out of way really like that myself. This is kind of pricey though, so $$ wise not a great value, BUT the real VALUE is its easy to handle and work with part even in awkward positions. I have a 9 amp/hr battery hooked to it usually and in a whole day of use never made battery go dead. They also give you a ripping guide also. No matter I still recommend it though. These tools are proven to be durable ... show more

    • Ok but not great
Great saw for small cuts in tight spots. My only complaint is the safety features for the blade guard and trigger gaurd make it awkward to operate almost unsafe ironically with all the contorting needed just to start the saw. Not a big deal but better design is needed.

    • Compact small saw for most common wood cutting needs
nice small saw for 85% of all the normal cutting that you will need to do. The saw makes easy work without all the bulk and fuss of larger saws.

    • The most handy saw you didn't know you needed!
This Dewalt Atomic Max circular saw is the saw you didn't know you needed. I used it to demo a shower/tube insert and it was a dream come true. I then used it to cut down the fiberglass insert into manageable pieces. I would HIGHLY recommend this saw, you won't regret it.

    • Very happy with this purchase!
I am a senior woman with a fair amount of DIY and remodeling experience, both commercial and residential. I appreciate well-designed, well-built tools, and this lived up to DeWalt’s standards. I was concerned that it would be heavy and clumsy for my grip, which is maybe a bit larger and stronger than many senior women, but not as big/strong as most guys’. While the tool is heavy, in a good way, the grip and trigger/switch design is smart, safety-forward, and I found it easy to hold and work with the tool. Both the kerf notch and the bevel selector needed small adjustments out of the box, but they were easily accomplished. The tool has plenty of power via the 20V battery system. I RTFM’d carefully, because I’m that kinda gal, and then I took my time with the first few cuts, getting used to the feel of the tool. I’m very pleased, posting this review to encourage other women who may be hesitating about which saw to buy. One final observation: the portability of this saw can’t be beat, so if the size of the blade works for your needs, go for it. ... show more
