    • Keep on cutting
This 4 1/2" saw is AWESOME. It works great for small projects. No need to bring out the big boy for those small projects. I feel the balance is on point once you add the battery. I do have the bigger batteries 6 AH and 9AH. I feel if you use the smaller battery, you might feel the saw tilt more on the saw side. Keep that in mind. Build solid and the motor rips though 2x6 boards with ease. Yes, I recommend ... show more

I bought this saw about a year ago (it’s actually my first saw), and it’s been pretty powerful. Back when I got it, I saw some reviews saying that bigger batteries were necessary to get the most out of it. At first, I was using a 5Ah battery, and it worked fine for plywood, studs, and general wood cutting. Recently, though, I decided to push it a bit further and tried cutting granite(yes, an actual granite countertop). That’s when I realized the 5Ah battery wasn’t enough. You could feel the resistance, and the saw just didn’t have the power to go through it smoothly. So, I got an 8Ah battery, and wow, what a difference! With a bigger battery, the cuts were flawless, fast, powerful, and effortless, obviously using the proper blade. I was already happy with the saw for regular use, but this recent challenge made me want to finally write a review. If you’re planning to use it for heavier materials, definitely go for the bigger battery and right blade. Overall, really impressed and glad I bought it! ... show more

    • The high quality of DeWalt with ergonomic design
This little saw is built solid. All moving parts are metal, and the aluminum casing contributes to its light weight. The brushless motor is strong and efficient. Safety levers on both sides keep you safe from accidental operation, for both left and right-handed users. It has an exhaust tube on one side that will emit most of the saw dust, and you can connect this to a small hose or bag to capture it (not included). The ergonomic design makes it very easy to handle overall. This saw can handle anything a 4 1/2 in. diameter blade was ever meant to take on. It also comes with a metal guide marked with inch units, which is useful for cutting straight lines. My only complaints: 1- This saw is significantly pricier than most. There are many cordless mini-saws out there that will do a great job for less cost. 2 - I wish DeWalt had included the laser guide feature installed in some similar or lesser models, to help cut a straight line. Although that's a just a personal preference, it's easy enough to add, and you should not feel like you got less when you pay more. Nonetheless, it was a choice I do not regret. For its power, durability and design, it still gets a 5 out of 5. ... show more

    • You should have saw!! HAHA
What an amazing little saw!! When I don't need to drag out the full-size circular saw, man, this thing fits the bill....especially for most home projects. I love it. I DID upgrade to a finer pitch blade for less chipping and splintering, but that's due to the materials I am cutting. I really like this tool. ... show more

    • Incredibly versatile small saw

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

    • Great tool!
This has become my go to saw for most of my work. Easy to handle and has plenty of power. Its just able to cut two by material and is very easy to manage on plywood cuts on walls for example since its so light. I agree its looks a little weird at first but I have grown to use my "axe"
