DeWalt 20V MAX XR Brushless Circular Saw DCS570B

Overview

The DeWalt DCS570B is a 20V MAX brushless circular saw with a full 7-1/4 inch blade. It runs at 5,500 RPM and cuts 2-9/16 inches deep at 90 degrees. For most framing, sheathing, and remodeling work, it replaces a corded circular saw without needing to step up to DeWalt's FlexVolt platform.

Pro Tool Reviews gave it an 8.1 out of 10, with a perfect 100 for value. Amazon reviewers rate it 4.7 stars across 5,547 ratings. Home Depot reviewers give it 4.8 stars across 2,800+ ratings. The consensus is clear: it's a solid, reliable cordless saw that does what most people need for significantly less money than the Milwaukee 2732.

The bare tool costs considerably less than the Milwaukee M18 FUEL 7-1/4 inch saw. The trade-off is less raw cutting power. The DCS570 will stall under loads that the Milwaukee pushes through. For daily professional framing, that matters. For home projects and light to moderate jobsite work, it doesn't.

Key Features

The brushless motor delivers 5,500 RPM through a 7-1/4 inch blade with a 5/8-inch arbor. The bevel adjusts from 0 to 57 degrees with positive detents at 22.5 and 45 degrees. That 57-degree max bevel is the widest in the cordless category (Milwaukee tops out at 50 degrees).

An electronic blade brake stops the blade in 0.55 seconds after you release the trigger. The aluminum shoe is flat and smooth, sliding over material without catching. A hex wrench stows in a clip behind the battery compartment, so you always have it for blade changes.

The saw has an LED work light, a rafter hook (on Type 2 models made after 2017), and a metal blade guard. It takes any DeWalt 20V MAX or FlexVolt battery. Bare tool weight is about 8 lbs. With a 5Ah battery, expect roughly 9.6 lbs.

Performance

In Project Farm's cordless circular saw shootout, the DCS570 cut a 2x4 in 2.12 seconds with moderate pressure (5 lbs of feed force). With 7.5 lbs of force, it completed the cut in 1.41 seconds. At 10 lbs of force, it stalled. The Milwaukee 2732, Makita, Bosch, and Flex all completed the 10 lb test. With a 12Ah FlexVolt battery, the DeWalt pushed through the same test in 0.9 seconds, so the motor has the capability when given enough voltage.

TechGearLab measured a 6x12 header crosscut at 6.4 seconds (Milwaukee did it in 4 seconds) and a 10-foot rip in a 2x12 at 46 seconds (Milwaukee did it in 35). DeWalt claims about 330 crosscuts per charge in 2x4 pine with a 5Ah battery.

Battery life is the main weakness. TechGearLab got 242 linear feet of plywood ripping per charge, while competitors managed 300+. Amazon reviewers confirm: "I can get about 1 hour of work on each battery" for moderate cutting. With a 2Ah battery, the saw drains fast and isn't practical. 5Ah minimum, and a FlexVolt battery dramatically extends runtime.

Noise is 91.1 dB in Project Farm's testing, which is on the quieter side for a circular saw (the Milwaukee hit 98.3 dB).

Build Quality & Design

The aluminum shoe is a strong point. It's flat, slides well, and won't crack if dropped (unlike magnesium). The bevel adjustment is smooth with clearly defined detents. The blade guard is metal, not plastic. Build quality is in line with DeWalt's professional-grade standards.

Amazon reviewers consistently praise the handling. "Handles beautifully and is straightforward, even intuitive, to use." One owner cut T1-11 plywood siding panels for sheds and outdoor buildings, using the saw on remote sites with no electricity, and called it "great."

One ergonomic knock: the push-in trigger safety requires pressing inward before pulling the trigger. Some users prefer the more common push-down safety style. Pro Tool Reviews gave ergonomics a 61 out of 100, the lowest score in their review.

A common note from Amazon reviewers: the blade is on the right side of the saw. If you've used left-blade saws your whole career, the sightline is different. Check the photos before ordering.

DeWalt backs it with a 3-year limited warranty plus 1 year of free service. Made in Mexico.

Value for Money

The DCS570B is the least expensive premium 7-1/4 inch cordless circular saw. The Milwaukee 2732-20 costs significantly more and cuts faster. The Makita XSH06Z matches the DCS570 on price but requires two 18V batteries to run (36V total). The Bosch CCS180B costs slightly less but uses a brushed motor and a smaller 6-1/2 inch blade.

If you already own DeWalt 20V MAX batteries, the DCS570 is an easy choice. It's compatible with the entire 300+ tool ecosystem and doesn't require buying into FlexVolt. A FlexVolt battery will work in it and extend runtime, but it's not required.

If you don't own any batteries yet and cutting power is your top priority, the Milwaukee 2732 is worth the premium. It's faster, doesn't stall under heavy load, and has a magnesium shoe. But for a homeowner or contractor doing moderate cutting, the DCS570 saves real money without giving up much.

Who Should Buy This

DIYers and homeowners who need a cordless circular saw for decking, sheathing, framing, and trim. The 7-1/4 inch blade handles all standard lumber sizes at 90 degrees.

Anyone already in the DeWalt 20V MAX ecosystem. The bare tool is affordable, and your existing batteries work immediately.

Contractors who want a lighter backup saw. At about 8 lbs bare, it's manageable for rooftop work and overhead cuts where weight matters.

Who Should Skip This

If you frame houses professionally and cut engineered lumber all day, the Milwaukee 2732 is the better saw. The stalling under heavy load is a real limitation for sustained structural work.

If you already own Milwaukee M18 batteries and tools, there's no reason to switch to DeWalt for one saw. The Milwaukee 2732 is the better performer in the M18 ecosystem.

If you need maximum runtime on a single charge, the FlexVolt DCS575 (60V) cuts more per charge and doesn't stall under load. It costs more, but for long days on remote sites without power, the runtime difference pays off.
