- Milwaukee®'s M18 platform covers 275+ solutions, offering one of the broadest cordless ecosystems available to professionals.
- DeWALT®'s 20V MAX XR line delivers strong performance at a generally lower price point, making it a solid pick for budget-conscious pros.
- Milwaukee® and DeWALT® batteries are not interchangeable, so your first choice locks you into an ecosystem.
- GenuineTools carries both brands at up to 60% off MSRP, so you can compare and commit without overpaying.
Which Performs Better: Milwaukee® 18V or DeWALT® 20V Tools?
Milwaukee® and DeWALT® make genuinely excellent tools that professionals stake their livelihoods on every day. As to which one is better, the honest answer is: it depends on the tool category.
Milwaukee® consistently edges out DeWALT® in raw power output and advanced motor technology, particularly in their FUEL line. DeWALT® counters with competitive performance in their XR brushless range, often at a lower price point. Neither brand is universally superior, but understanding where each excels helps you make a smarter investment, especially when you're building out a full platform over time.

Milwaukee® M18 Tools
Milwaukee®'s M18 platform is among the most expansive cordless ecosystems ever built, with compatibility across 275+ solutions. The FUEL sub-line represents Milwaukee®'s premium tier, featuring three proprietary technologies that work together to deliver professional-grade performance:
- POWERSTATE™ Brushless Motor delivers consistent power under load without the heat and wear of brushed motors
- REDLINK PLUS™ Intelligence onboards electronics that protect against overload, overheating, and over-discharge
- REDLITHIUM™ Battery Technology, including the FORGE HD12.0, which pushes runtime and power delivery to new levels
These translate directly into measurable results across Milwaukee®'s tool lineup, from their M18 FUEL Circular Saw to their Random Orbital Sander.
Performance
The Milwaukee® M18 FUEL 2834-20 Circular Saw is a prime example of what this platform can do. Paired with an M18 REDLITHIUM FORGE HD12.0 battery, it delivers up to 750 cuts per charge. It features a 57° bevel capacity, right-blade configuration, and positive bevel and depth detents for faster setup on the job.
The Milwaukee® 2834-20 Circular Saw lets you cut 750 times on a single charge.
The Milwaukee® M18 FUEL 2737B-20 Barrel Grip Jig Saw, which is another good example, runs at 0–3,500 strokes per minute across 6 speed settings, giving users precise control through hardwoods and metals alike. Similarly, the M18 FUEL 2837-20 Random Orbital Sander (2837-20) hits 12,000 OPM and delivers the lowest cordless vibration in its class, achieving up to 95% dust collection efficiency when paired with the M18 FUEL PACKOUT Dust Extractor, while the included dust bag also provides meaningful dust capture for jobsite cleanup. That's a meaningful spec for anyone doing interior finish work.
Price
Milwaukee®'s M18 FUEL tools sit at the premium end of the market, and the pricing reflects that positioning:
- M18 FUEL Barrel Grip Jig Saw (2737B-20): $159.99 at GenuineTools (Tool Only)
- M18 FUEL 7-1/4" Circular Saw (2834-20): $229.99 at GenuineTools (Tool Only)
- M18 FUEL 5" Random Orbital Sander (2837-20): $149.99 at GenuineTools (Tool Only)
As these are tool-only prices, batteries and chargers are sold separately. If you're already invested in the M18 ecosystem, that's a non-issue. If you're starting fresh, factor in the cost of at least one REDLITHIUM battery.
DeWALT® 20V MAX Tools
DeWALT®'s 20V MAX platform is the brand's answer to professional-grade cordless performance, and the XR (eXtreme Runtime) brushless sub-line is where the serious tools live.
Like Milwaukee®'s M18 FUEL lineup, DeWALT® XR tools use brushless motor technology. However, DeWALT®'s approach emphasizes durability engineering and jobsite versatility, with protection systems built into each tool.
Performance
The DeWALT® 20V MAX XR DCS382B Brushless Cordless Reciprocating Saw is a strong performer in DeWALT®'s lineup. It's engineered for everything from light construction framing to heavy demolition, powered by a high-efficiency brushless motor that maintains consistent speed under load. The tool features a durable, high-impact housing engineered to handle jobsite abuse.
The DeWALT® 20V MAX XR DCS382B cordless reciprocating saw sustains its speed even under loads.
DeWALT®'s electronics package mirrors Milwaukee®'s protective approach. Every XR tool works with the XR battery system to protect against:
- Overloads: prevents motor burnout during heavy cuts
- Overheating: thermal management keeps performance consistent in sustained use
- Over-discharge: protects battery cell integrity to extend overall pack life
DeWALT® also integrates jobsite dust-control features directly into compatible tools, which speeds cleanup and keeps work areas safer during finish applications.
Price
DeWALT® generally positions its tools at a more accessible price point than Milwaukee®'s FUEL line. The DeWALT® 20V MAX Brushless Reciprocating Saw (DCS382B) is available for $107.99 at GenuineTools (Tool Only), offering significant savings compared to comparable Milwaukee® FUEL options. This pricing makes DeWALT® especially attractive for contractors who need to outfit a crew without blowing their tool budget in a single purchase.
DeWALT®'s 20V MAX batteries are priced competitively as well, and the platform spans a wide enough tool range that most trades professionals can build a complete kit within the ecosystem. Just like Milwaukee®, DeWALT® tools are sold tool-only in most cases, so battery investment is a separate line item to plan for.
Various DeWALT® 20V MAX XR tools are available at GenuineTools.

Frequently Asked Questions (FAQs)
Are DeWALT® 20V and 18V the same?
Yes, DeWALT® 20V MAX and 18V are essentially the same in terms of real-world operating voltage. The 20V MAX rating refers to the peak open-circuit voltage of the battery, the voltage measured when no current is flowing. The "20V" label is largely a marketing distinction, not a performance one.
Under load, which is the only condition that actually matters when you're using the tool, DeWALT®'s 20V MAX batteries operate at the same 18V nominal voltage as Milwaukee®'s M18 batteries.
Are DeWALT® and Milwaukee® 18V batteries the same?
No, DeWALT® and Milwaukee® batteries are not interchangeable. While both operate at 18V nominal voltage under load, the physical connectors, internal cell configurations, and battery management systems are completely different. A Milwaukee® REDLITHIUM™ battery will not fit into a DeWALT® tool, and vice versa.
Why does Milwaukee® use 18V instead of 20V?
Milwaukee® uses the 18V designation because it reflects the actual nominal voltage (the real operating voltage under load) rather than the peak open-circuit voltage. This is the more technically accurate way to rate a battery, and Milwaukee® has consistently chosen transparency in its voltage labeling.
Can I use my DeWALT® 18V battery in a 20V tool?
No. DeWALT® transitioned from its older 18V NiCad system to the current 20V MAX lithium-ion platform, and there is no official adapter that allows older 18V NiCad batteries to be used in newer 20V MAX tools. The migration path works the other way: DeWALT®'s DCA1820 adapter lets you use new 20V MAX batteries in most older 18V tools, so you can upgrade your batteries without replacing your entire 18V tool collection. If you're looking to move to 20V MAX tools, you'll need 20V MAX batteries to go with them.
What Milwaukee® and DeWALT® tools are available at GenuineTools?
GenuineTools carries a strong selection from both brands, covering the most in-demand professional tool categories. On the Milwaukee® side, you'll find M18 FUEL lineup staples including the Milwaukee® M18 FUEL 7-1/4" Circular Saw (2834-20) at $229.99, the Milwaukee® M18 FUEL Barrel Grip Jig Saw (2737B-20) at $159.99, and the Milwaukee® M18 FUEL 5" Random Orbital Sander (2837-20) at $149.99, all available as tool-only options for those already invested in the M18 platform.
For DeWALT®, the inventory includes the DeWALT® 20V MAX XR Brushless Cordless Reciprocating Saw (DCS382B) at $107.99, one of the best entry points into the 20V MAX XR ecosystem for contractors who need reliable demo and cutting performance without the premium price tag of Milwaukee®'s FUEL equivalents.
