Incredibly versatile small saw
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

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.

Mostly good, but had to fix flaw
The saw is sturdy and worked well for my project, except the nut that tightens the depth guide has a design flaw. It hits the guide and is impossible to tighten all the way. I had to add 2 washers to create enough space to clear the guide. See video. Also, it says the only thing in the box is the saw. There’s nothing about a blade. So I ordered blades for it, but I when opened the box. there was a carbide tipped blade inside. Would’ve been nice to know. ... show more

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.

One of My Most Used Tools
I already own a full size framing saw and even a mid size cordless circular saw, so I really thought I did not need this saw at all. I ended up buying it on a whim, thinking it might be handy for trimming some vinyl floor or perhaps doing small jobs around the house. Now it has become one of my most used tools. I've used it for drywall, plywood, fencing, flooring, and even an occasional 2x4. It is just a great light, versatile saw that requires no setup and cuts great. Unless I have a big cutting job to do, I'll always reach for this saw first. For example, recently I had some bad sections of decking to remove, but I did not want to replace the entire 12 foot deck boards because the screws are all shot, and I wanted to minimize damage to the joists. So I set this saw to the right depth and did a precise plunge cut over the joists, and then finished the cut with an oscillating tool. Then I used the mini saw to cut the portion I wanted to replace up and then cut off the rusted screws with a dremel. This is a super handy tool - great for small projects, and more useful than a large circular saw for most casual users, though I'm sure a pro would find many uses for it as well. ... show more
