DEWALT Flexvolt DCS577 60V Brushless 7-1/4″ Rear Handle Circular Saw Review

#1 In Power!

DEWALT call their new Flexvolt DCS577 60V Brushless 7-1/4″ Rear Handle Circular Saw a Worm Drive Style Saw.  DEWALT’s saw does not have worm drive gears, hence they call it a worm drive style.  We like to call this a rear handle, blade left saw. The blade is oriented to the left of the motor and the handle is at the rear to optimize line of sight when cutting.  DEWALT included an electronic blade brake to quickly stop the blade after the trigger is released.  The DCS577 has a max bevel capacity of 53° with stops at 45° and 22.5°.  The Flexvolt saw has a max depth of 2-7/16 in. at 90° and 1-7/8 in. at 45°.  Also included with the rear handle saw is a folding rafter hook.  DEWALT backs this saw with a 3-year limited warranty, 1-year free service contract, and 90-day money-back guarantee.

DEWALT DCS577X1 FLEXVOLT 60V MAX 7-1/4″ Worm Style Saw Kit with 9.0Ah Battery

Power in battery operated circular saws has been rapidly increasing to the point where we now have battery operated models that can hang with corded worm-drive circular saws.  With that power is also a capacity to cut for long periods of time without a thermal timeout of the brushless motor or battery pack.  Prior to the DEWALT saw, the Makita XSR01Z 18V X2 Brushless Rear-Handle Circular Saw held the honors of most power and great capacity using two 18-volt batteries.  DEWALT raised the bar with more power, but the Makita is not far behind.  Both saws have the runtime to support the cutting on a large jobsite were they will be in use constantly.

  • Electronic brake
  • Bevel capacity of 53° with stops at 45° and 22.5°
  • Magnesium shoe and a brushless motor

  • Includes a rafter hook
  • An integrated dust blower

FlexVolt Rear Handle Saw

DEWALT is going after the contractors and working to make sure that every jobsite has the yellow and black FlexVolt tools on-site.  Many of their tools are performing in the top of the battery operated platforms and they continue to release more and more tools that are best in class.  Even the weight of this saw at almost 13 pounds with the battery is right on par with its corded counterpart.  so when someone has the option for a corded or cordless model circular saw that weighs the same, with the same power and capabilities, what will they choose?  The only big item that separates the two at this time is the price.  Corded models are much cheaper.  Either way, the option for cordless is now available without compromise.

    The makita rear handle was not the most powerful cordless saw until this. It may be tied with the dcs575 from Dewalt but not More powerful.and the new dcs 577 is Much more powerful then the makita.,really it’s not that close.
    …….I’m a Framer for 30 plus yrs. I run two large framing companies. We carry both both brands, Dewalt and Makita, some Bosch and Milwaukee…We use all the Flexvolt tools and new Makita tools. …I appreciate your videos and it’s ok to say Dewalt Flexvolt tools reigns supreme, you don’t have to be PC because you guys get free tools to review.
    ……Honesty will bring about change for tool companies, instead of appeasing them.

    • Hey Joe, I read your comment over 4 times and I am unsure how to take it. I guess I will start with the saws. I firmly believe that the Makita XSR01Z 18V X2 Brushless Rear-Handle Circular Saw is more powerful than the first Dewalt Flexvolt Circ saw. See here: https://www.youtube.com/watch?v=qnjRd89ujZc

      Personally, I dislike what Dewalt has done with their battery platform in general, but they are starting to get back in the game with some of the new tools.

      I am not a very PC guy and I like to say what I feel. Dewalt does not pay me and I doubt the marketing people even watch my videos. I call it as I see it.

      On another note, unless we have a circular saw dyno, we can disagree about the two saws and what one is more powerful. That is cool to me. They are both good saws, I just feel the Makita will go longer without a thermal cutout and has a better battery platform using two 18 volt batteries. I also feel that Makita had more power, up until now.

      Keep the comments coming! Its nice to hear opinions and real world thoughts from our readers!

    So just on the merits of the saw, not the battery platform which saw do you like better and why, the dewalt or the makita. I am looking for your opinion. Thx in advance.
