The single deciding factor when comparing the DeWalt DCS570 against the DeWalt DCS573 is dynamic motor power under demanding framing conditions. Both circular saws run full-size 7-1/4-inch blades driven by brushless motors spinning at 5,500 RPM, but the DCS573 features DeWalt FlexVolt Advantage technology that identifies the attached battery pack and draws up to 77% more power when paired with a DCB606 FlexVolt battery instead of a standard DCB205 20V MAX pack. The DCS570 relies on a fixed 900-watt motor output on standard 20V MAX batteries, delivering dependable everyday performance in a significantly lighter 7.5-pound chassis.
Carpenters tackling continuous framing passes, dense engineered lumber, or wet structural timbers should choose the DCS573 for its torque reserves and jobsite conveniences. Tradespeople prioritizing overhead comfort, light weight, and standard sheet-goods cutting should pick the DCS570.

Motor Output and FlexVolt Advantage Power
Motor output dictates whether a cordless saw bogs down in thick lumber or powers steadily through long rip cuts. In a dewalt dcs570 vs dcs573 power evaluation, the fundamental difference lies in how their internal electronics communicate with battery packs. The DCS570 houses a standard brushless motor rated at 900 watts that spins at 5,500 RPM to maintain speed under moderate loads. This provides ample cutting speed for conventional framing studs and subflooring panels. Its manufacturer specifications document a runtime capability of up to 330 crosscuts in 2×4 pine on a single charge, demonstrating solid efficiency across everyday residential carpentry applications.
The DCS573 upgrades this architecture with dewalt dcs573 flexvolt advantage engineering. While it also produces a baseline no-load speed of 5,500 RPM on standard 20V MAX packs, the internal software detects when a 60V MAX FlexVolt battery is attached. When paired with a DCB606 FlexVolt battery rather than a standard DCB205 20V MAX battery, the saw releases up to 77% more power. This massive burst of torque prevents the blade from stalling when ripping through wet treated lumber, thick LVL headers, or stacked plywood. If you are comparing heavy-duty saws across brands like in our dewalt dcs570 vs milwaukee 2730-20 breakdown, you know that sustained torque under heavy load is what keeps production work moving.
Choosing between these two power delivery profiles comes down to whether your cutting tasks routinely strain a standard 20V motor. The DCS570 never increases its ceiling beyond its 900-watt design, which remains completely sufficient for dimensional 2×4 lumber and sheet ripping. The DCS573 eliminates bogging during aggressive cuts, making it the superior power plant when continuous cutting velocity is mandatory on commercial jobsites.
Edge: DeWalt DCS573 because its FlexVolt Advantage electronics unlock up to 77% more power when paired with high-capacity FlexVolt batteries.
Weight, Form Factor, and Handling Ergonomics
Physical handling becomes critical when carrying a cordless circular saw across joists, cutting rafter tails on ladders, or breaking down sheet goods for hours at a time. The dewalt dcs573 vs dcs570 weight discrepancy is immediately apparent in the hand. The DCS570 weighs 7.5 pounds bare, featuring compact frame dimensions of 11 inches long, 8 inches wide, and 10 inches high. This short front-to-back layout makes the DCS570 exceptionally nimble, allowing operators to maneuver between tight framing bays and make precise overhead cuts with minimal shoulder strain.
By comparison, the DCS573 registers an unequipped weight of 8.2 pounds, adding nearly three-quarters of a pound of bare metal and reinforced housing to accommodate its heavy-duty electronics. Its dimensions expand to 15.25 inches long, 9.75 inches wide, and 8.25 inches high. When you add a multi-cell FlexVolt battery pack to activate the power boost, the working weight differential widens even further. As detailed in our dewalt dcs570 vs dcs391 comparison, saw mass directly governs physical fatigue over extended work shifts.
For users who cut mostly 1/2-inch and 3/4-inch sheathing or general dimensional lumber at waist height, the extra weight and extended length of the DCS573 provide no handling advantage. The DCS570 delivers the classic feel of a lightweight framing saw that is easy to wield one-handed during staging or trim work. However, the added mass of the DCS573 does help stabilize the shoe against the workpiece during long, straight rip cuts.
Edge: DeWalt DCS570 because its 7.5-pound bare weight and compact 11-inch footprint reduce fatigue during prolonged or awkward cutting positions.
Cut Depth and Bevel Versatility
Both models feature a standard 7-1/4-inch blade geometry that allows cordless saws to match the cutting depth of traditional corded tools. In this dewalt 7 1 4 circular saw comparison, both tools share an identical maximum cutting depth of 2-9/16 inches at a 90-degree square angle. This depth allows both saws to cleanly slice through two-by dimensional lumber in a single pass with ample blade exposure underneath to clear chips efficiently.
Where these tools diverge in the product data is bevel geometry and published angular capacity. The DCS570 features a bevel capacity that tilts up to 57 degrees, giving carpenters extended reach beyond standard 45-degree cuts for complex compound miters, valleys, and unusual roof pitches. The DCS573 product data specifies a maximum depth of cut of 2 inches at 45 degrees, confirming it easily severs standard framing material on a bevel, but its listing leaves its absolute maximum bevel angle unspecified. For users evaluating compact saws in articles like dewalt dcs573 vs dcs391, full 2-inch clearance at 45 degrees remains a critical benchmark for structural work.
When asking dewalt dcs570 or dcs573 for framing, both units satisfy the basic dimensional criteria for wall studs and floor joists. However, the DCS570 provides documented versatility for aggressive roof framing angles thanks to its rated 57-degree bevel stop. The DCS573 handles standard 45-degree compound passes with ease, but the DCS570 provides greater documented flexibility on extreme rafter angles.
Edge: DeWalt DCS570 because of its verified 57-degree bevel capacity that accommodates steep compound cuts.
Jobsite Convenience and Storage Features
Framing tasks require quick staging and secure tool storage between cuts. The DCS573 incorporates practical features engineered specifically for active production jobsites. Chief among these is an integrated fold-out rafter hook. When working on staging, roof trusses, or saw horses, the rafter hook allows you to hang the saw safely from nearby framing members rather than resting it on dusty floors, balancing it precariously on wall plates, or climbing down ladders to set it aside. The DCS570 listing does not mention an integrated rafter hook.
Asset management is another modern jobsite consideration covered on the DCS573. It comes Tool Connect Chip Ready, featuring a built-in pocket that accepts the DCE042 Tool Connect Chip (sold separately). This allows commercial contractors to track the saw through the Tool Connect Site Manager mobile app for inventory control and loss prevention. Similar commercial hardware differences appear when comparing tools in our dewalt dcs573 vs makita xsh04z overview, where jobsite integration frequently separates standard consumer tools from commercial-grade equipment.
Both saws incorporate blade brakes that rapidly stop the spinning 24-tooth blade after the trigger is released, reducing the risk of accidental workpiece gouging or personal contact between cuts. However, the DCS573 integrates modern jobsite conveniences that streamline day-to-day workflow, protect the tool from drop damage, and integrate into enterprise inventory tracking systems.
Edge: DeWalt DCS573 because of its built-in rafter hook and integrated Tool Connect chip pocket.
Dust Management and Cut-Line Visibility
Keeping cut lines visible while maintaining clean indoor air is a priority for residential remodeling and finish work. The DCS573 arrives out of the box with an included dust port attachment. This port is engineered to connect directly to the DeWalt AirLock quick-connect system or fit standard 35 mm dust extractor hoses. When connected to a jobsite vacuum, the DCS573 captures airborne wood particles right at the blade guard, preventing dust clouds inside occupied client homes and keeping the shoe path free of accumulated sawdust.
Visibility along the cut line also differs sharply between these two saws. The DCS573 includes a bright LED worklight situated on the motor housing that illuminates the front pointer and blade entry point. This onboard lighting makes following pencil marks easy in dimly lit basements, unpowered new construction, or shadowed corners. Similar workflow advantages are explored in our dewalt dcs573 vs milwaukee 2730-20 head-to-head analysis, highlighting how built-in task lights improve cutting accuracy.
The DCS570 package includes only the 7-1/4-inch circular saw, a 24-tooth blade, and a blade-changing wrench. Its listing does not include an auxiliary dust collection port, nor does it list an integrated LED worklight. If you primarily cut outdoors on rough framing where sawdust dispersal is unconstrained and ambient daylight is abundant, the DCS570 performs admirably. However, for interior renovation, accurate line tracking in dim light, and active dust extraction, the DCS573 offers clear functional superiority.
Edge: DeWalt DCS573 because it includes an integrated dust extraction port and a bright LED cut-line light.
