    • 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

    • 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.

    • 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

    • DEWALT ATOMIC 20V MAX* Circular Saw Review: Power in a Compact Package
The DEWALT ATOMIC 20V MAX* Circular Saw delivers impressive performance in a compact and portable design. Despite its smaller size, this circular saw packs a punch with its powerful motor, effortlessly cutting through various materials with precision and ease. One of the standout features of this saw is its ergonomic design, which allows for comfortable and controlled operation, reducing user fatigue during extended use. The lightweight construction makes it easy to maneuver, even in tight spaces or overhead applications. The 4-1/2-inch blade size may seem small compared to traditional circular saws, but it offers the advantage of increased maneuverability and versatility, making it ideal for a wide range of cutting tasks. Whether I’m working on trim, plywood, or other materials, this saw delivers consistent and accurate results every time. The built-in dust blower helps keep the cutting line clear of debris, improving visibility and accuracy. Additionally, the tool-free depth adjustment and bevel capacity enhance convenience and efficiency, allowing for quick and easy adjustments on the fly. Overall, the DEWALT ATOMIC 20V MAX* Circular Saw is a reliable and efficient tool for both professional contractors and DIY enthusiasts ... show more
