DEWALT DCS570 20V 7-1/4″ Circular Saw with Blade Brake Review

FlexVolt’s Little Bro

DEWALT DCS570 20V 7-1/4" Circular Saw with Blade Brake ReviewDewalt added a new brushless 7-1/4″ circular saw to the 20 volt max lineup as part of a growing brushless tool selection.  Dewalt’s first brushless circular saw was the 60v Flexvolt the only runs on the new 60V batteries that can also be used on the 20V line.  The new DCS570 is directly meant to allow Dewalt 20 volt users to have a more powerful and up to date choice in circular saws.  This saw includes a lot of features found in the FlexVolt saw, including an included blade brake.

It is nice to see Dewalt expand 20 volt line with a new brushless circular saw as it provides a bit of insight to current 20 volt users.  The FlexVolt battery made the water a bit muddy as to where Dewalt was going to place research and development dollars.  The outlook has been that Dewalt was going to place the premium products in the FlexVolt line and push high end users into the new platform.  The new 20 volt circular saw has a 2-9/16″ cutting capacity at 90 degrees that can cut 3 by lumber in a single pass.  Electric blade brakes are included on many pro model saws and it is nice to see it on the new 20 volt.  Similar to the FlexVolt, the shoe on the new 20 volt is made out of aluminum.

FlexVolt Similar

DEWALT DCS570 20V 7-1/4" Circular Saw with Blade Brake ReviewLet’s really cut to the chase, the new 20 volt circular saw is almost identical to the FlexVolt circular saw (DCS575).  About the only difference in appearance is the color of the blade guard.  Both Dewalt saws have a high grade aluminum shoe, or base plate.  Internally, the motor is different and the saw runs at a slightly lower RPM of 5500 vs the FlexVolt at 5800 RPM.  There is a pretty fair difference in the performance and speed of cut side.  While the 20 volt is no slouch, it will not rip through 3 sheets of OSB at the same speed as the FlexVolt.

If you are using these saws all day long, in bare tool form, they weigh in at about the same weight, 7.5 lbs.  But add in the weight of a Flexvolt battery and the 20 volt will win as a lighter tool at the scales all day long.

DCS570 Features

  • 2-9/16″ max cutting capacity at 90°
  • 5,500 RPM max
  • 57° bevel with stops at 45° and 22.5°
  • Rubber overmold on handle
  • Blade brake
  • High grade aluminum base plate
  • Weighs 7.5 lbs

POWER

DEWALT DCS570 20V 7-1/4" Circular Saw with Blade Brake ReviewSo the question everyone want to know, does the FlexVolt look alike saw have the same power?  Well, we are sorry to say, but the answer is “No”.  That is not to say that is does not have the power to keep everyone on the jobsite happy.  It will rip and cross cut two by lumber without issue.  The place where it lacks is when stacking multiple pieces of OSB and making cuts.  Stacking three 3/4″ sheets can take the saw down to a crawl or worse.

If someone is looking for one the most powerful saws on the market, they should look to the FlexVolt in Dewalt’s offerings.  We did run the FlexVolt battery in this saw and found an increase in runtime, but not an increase in power.  We are getting spoiled with some super-powerful saws coming out and our expectations might be a bit high.  This upgrade makes the older brushed Dewalt saw look really slow.  If you are planted in the 20 volt max line, this is a good buy.

    Very nice write up! I work a lot of off-grid jobsites and currently have the flexvolt circ saw. The power is nice, but the poor runtime is really a downer… Leaving me to wonder just how much longer the 20v max brush less circ saw lasted during your testing? I have looked everywhere on the internet, but can’t seem to find any kind of definitive answer… I am tempted to buy it and publish the results myself, but I would assume yall would know since you already tested both saws side by side with the 9.0 battery.

    I myself (and many others I’m sure) would gladly trade a bit of power for a substantial increase in runtime. Thank you for your time and input! -Bear

      That’s because when running 60v it’s only a 2 ah battery
