Power Performance: Which Saw Cuts Deeper?
Both the DeWALT® DCS590 and Milwaukee® 2830-20 deliver impressive performance that rivals many corded models.
Motor Specs and RPM Comparison
The heart of any circular saw is its motor, and both manufacturers have invested heavily in brushless technology that maximizes efficiency and power. DeWALT®'s brushless motor in the DCS590 delivers 5,500 RPM with up to 1,700 MWO, while Milwaukee®'s POWERSTATE brushless motor pushes the 2830-20 to 5,800 RPM with 15A corded equivalent power.
This 300 RPM difference might seem minimal on paper, but it contributes to the Milwaukee®'s slightly more aggressive cutting feel. Both motors utilize rare earth magnets and sophisticated winding techniques to maximize power while minimizing heat generation.
Battery Platform Differences
DeWALT®'s 20V Max platform pairs perfectly with their DCS590 circular saw, though the saw performs noticeably better with their higher capacity 4.0Ah batteries and above. For maximum performance, the saw can also accept DeWALT®'s FlexVolt batteries, which provide extended runtime and slightly more power to the motor.
Milwaukee®'s M18 FUEL (2830-20) was designed specifically to make the most out of their HIGH OUTPUT batteries, with the saw reaching its full potential when paired with their HD12.0 battery. The Milwaukee® battery system generally delivers more consistent power throughout the discharge cycle, whereas the DeWALT® system shows a more gradual power decline as the battery depletes.
This difference becomes apparent during all-day use, where the Milwaukee® maintains its cutting performance more consistently until the battery is nearly depleted.
Cutting Depth at 90° and 45° Angles
When examining cutting depth capabilities, the Milwaukee® M18 FUEL has a maximum cut at 90 degrees with 2-1/2" versus DeWALT®'s 2-9/16" on the DCS590, giving DeWALT® a slight advantage in cutting depth.
This difference becomes more relevant when making bevel cuts, where the Milwaukee® maintains 1-7/8" depth at 45 degrees compared to DeWALT®'s 2". Both saws feature smooth, positive-locking bevel adjustment mechanisms, though the Milwaukee® has a maximum bevel capacity of 53 degrees while the DeWALT® extends to 57 degrees with stops at 45° and 22.5°.
For contractors who frequently make bevel cuts in thicker materials like 2x dimensional lumber, DeWALT®'s deeper cutting capacity and greater bevel range provide more versatility.
Price Breakdown: What You Get For Your Money
The DeWALT® DCS590 offers a more budget-friendly entry point with bare tool pricing typically ranging from $179–249, while the Milwaukee® 2830-20 is competitively priced. (Source: DeWALT®)
Bare Tool Costs
The price gap between these flagship models is minimal. DeWALT®'s DCS590 bare tool at $179–249 represents an excellent value entry point to professional-grade cordless circular saw performance, especially for users who already own compatible 20V Max batteries.
Milwaukee® positions the 2830-20 competitively at $189.99–279, offering exceptional value with its 15A corded power equivalent and superior runtime capabilities. For budget-conscious buyers who prioritize value while still requiring professional capabilities, both options offer compelling value propositions at similar price points.
Kit Pricing With Batteries
When comparing complete kits, pricing varies based on included battery capacity and accessories. A typical Milwaukee® 2830-20 kit with a HIGH OUTPUT battery and charger may range from $300–400, while DeWALT®'s comparable kit with a 5.0Ah battery typically sells for $299–329.
The pricing reflects each manufacturer's positioning, though seasonal promotions and bundle deals can occasionally narrow or remove these gaps significantly.

Its more accessible price point, excellent ergonomics, and slightly lighter weight make it well-suited for intermittent intensive use.
Best for Professionals
Professionals who use their circular saw daily for finish work, cabinet installation, cutting dimensional lumber and engineered materials will generally find the Milwaukee® 2830-20 better suited to their high-demand applications. Its 15A corded equivalent power, more aggressive cutting character, and superior runtime with the HD12.0 battery (up to 570 cuts per charge) make it the better choice for professionals who put their tools through punishing daily use.

Frequently Asked Questions
Which circular saw is better for professional framing work?
The Milwaukee® M18 FUEL (2830-20) is generally better suited for professional framing contractors who make hundreds of cuts daily through dimensional lumber. Its 5,800 RPM motor, 15A corded equivalent power, and superior runtime with the HD12.0 battery (up to 570 cuts per charge) make it ideal for demanding applications like cutting engineered I-joists, LVL beams, and pressure-treated lumber where maximum power consistency and extended runtime matter most. The rear handle worm drive design also provides excellent control for framing applications.
Is the DeWALT® DCS590 worth buying if I already own Milwaukee® batteries?
If you're already invested in Milwaukee's M18 battery platform, it rarely makes financial sense to switch to DeWALT® solely for the circular saw, despite its comparable price point. The cost of purchasing new batteries and chargers typically outweighs any price difference between the saws.
Can both saws cut through engineered lumber like LVL beams?
Yes, both the DeWALT® DCS590 and Milwaukee® 2830-20 handle engineered lumber including LVL beams, laminated joists, and pressure-treated dimensional lumber effectively. The Milwaukee® demonstrates slightly better performance consistency when making repeated cuts through these dense materials, maintaining more consistent blade speed under heavy load.
