Impressive and powerfull saw
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!

Great tool
There is a lot of power in this small saw. Cut through plywood like butter. Very easy to handle, no kick-back.

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.

Dewalt small circular saw
This saw is strong and lite, packs a punch ! Ideal for small jobs, gets in tight spots. Would order this again , use for cutting tile , very handy , can't beat the value for the price

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

Dewalt tools are for women too.
This 4 inch circular saw has given me the freedom to make and fix projects multiple times. Being much lighter than a regular sized saw, it is functional, powerful, well built and fairly priced. I have used it to enclose cabinets, make shelving, make slates for my bed and plywood support for mattress. I can even cut thick boards by cutting part way and turning to cut the rest. The light is very helpful to increase accuracy. I have several Dewalt tools and prefer this brand.

My nephew told me to get this…. My question was “where would I use it?” Question was answered quickly…. Always use it and hardly use my electric saw anymore! Love this thing!

IDEAL PARA CORTAR PUERTAS MEDIDA STANDAR, SOLO HICE PEQUEÑOS CORTES, BUEN FILO DEL DISCO INLCUIDO Y NOTABLE POTENCIA, BIEN CONSTRUIDA, YA ACTUALIZARE LOS COMENTARIOS MAS DELANTE, LE DI 4 ESTRELLAS EN VESATILIDAD SOLO PORQUE EL PESO DE LA HERRAMIENTA ES CONSIDERABLE PARA SER DE ESTE CATEGORIA NO SE DIGA CON LA BATERIA PUESTA, DEBO AGREGAR QUE EN GENERAL ES MUY PROMETEDORA, La Volví a usar con excelentes resultados para algunos será un capricho para mí comodidad y versatilidad, estoy considerando jubilar mi vieja confiable de 7 1/4 a 120 ac o talvez haga mi museo de herramientas antiguas 😝

Cette scie se manipule facilement et sans encombrement de fils puisqu'elle est alimentée par une batterie (qui n'est pas fourni lors de l'achat). Par contre, si tu possèdes déjà une ou des batteries Dewalt cet achat est parfait (moins cher qu'avec l'achat d'une batterie). Coupe très bien le bois avec sa petite lame. De plus, vu que celle-ci est plus petite, elle est moins lourde que les grosses scies circulaires. Cet outil a facilité nos travaux pour le patio, dans la maison. Le seul regret que nous ayons, moi et mon conjoint, c'est de ne pas l'avoir acheté avant. De plus, cette scie sera parfaite pour les petits travaux futurs, nous voyons cela comme un très bon investissement. Un achat fort utile et sans aucun regret car très bon produit pour la qualité/prix.

La Herramienta es muy práctica para recortar, la madera en obra. Te ayuda a no traer herramientas más grandes y un poco estorbosas. Aunque la limitación es el diámetro del corte que permite cortar. Pero para cortar melamina es también muy práctica, solo hay que cambiar le el disco con más dientes para no astillar la melamina.
