Oscillating Multi-Tools: Milwaukee® vs DeWALT®
Cordless oscillating multi-tools from Milwaukee® and DeWALT® dominate professional jobsites for a reason: both platforms cover cutting, sanding, and grout removal in a single tool. The real difference between them sits in the motor technology: Milwaukee®'s M12 and M18 models run brushed motors with a wider 3.2°–3.4° oscillation arc for aggressive material removal, while DeWALT®'s ATOMIC and XR models use brushless motors with a tighter 1.6° arc built for controlled, precision cuts.
Across the four models worth considering, tool-only pricing starts under $75 and tops out at just under $140 for a complete kit with battery and charger. GenuineTools carries the full lineup at up to 60% off MSRP, making it straightforward to compare specs and pricing in one place before committing.

Milwaukee® Oscillating Multi-Tool Specs & Features
Milwaukee® offers two main cordless oscillating multi-tools worth considering: the compact M12 for lighter tasks and the powerhouse M18 for full jobsite demands.
Milwaukee® 2426-20 M12 Oscillating Multi-Tool
The Milwaukee® 2426-20 is the brand's 12-volt entry point into oscillating tools. It's designed for remodelers, flooring contractors, and maintenance techs who need a capable, lightweight option that doesn't sacrifice professional performance.

How Much Does It Cost?
The Milwaukee® 2426-20 M12 Oscillating Multi-Tool is priced at $73.99 at GenuineTools for the tool-only configuration. No battery or charger is included, so factor that in if you're not already running M12 batteries.
Milwaukee® 2626-20 M18 Oscillating Multi-Tool
The 2626-20 oscillating multi-tool runs on the Milwaukee® M18 ecosystem.
The Milwaukee® 2626-20 is one of the most versatile cordless jobsite tools available, built for sustained power through dense materials without voltage sag. What sets it apart from the M12 is Constant Power Technology, which maintains speed and output under load, so it won't bog down in hardwood or adhesive.
Key Specs
- Voltage: 18V
- Motor Type: Brushed
- OPM: 11,000–18,000 (variable)
- Oscillation Arc: 3.4°
- Weight: 3.38 lbs
- Battery Included: No (Tool Only)
- Power Features: Tool-Free Blade Change, Variable Speed, Constant Power Technology, Built-in LED Light
- Battery Platform: M18 (250+ compatible tools)
How Much Does It Cost?
The Milwaukee® 2626-20 M18 Oscillating Multi-Tool is available for $74.99 at GenuineTools for the tool-only version. Given the jump in power and the Constant Power Technology included at this price point, the M18 represents strong value for anyone already in the Milwaukee® M18 ecosystem.
DeWALT® Oscillating Multi-Tool Specs & Features
DeWALT's oscillating multi-tool lineup sits inside the 20V MAX platform, with two main options: the compact ATOMIC DCS354B and the premium XR DCS356C1. Each targets a different user with distinct priorities.
DeWALT® DCS354B ATOMIC 20V MAX Oscillating Multi-Tool
The DCS354B is a compact, lightweight tool that doesn't cut corners on performance. At 11.2 inches long, it's built for precision work in tight spaces where a bulkier tool would struggle. Its brushless motor delivers up to 57% more runtime than brushed alternatives per charge.
A built-in LED work light illuminates dark surfaces like cabinet interiors, and the Quick-Change system enables tool-free blade swaps with most universal accessory brands.
Key Specs
- Voltage: 20V MAX
- Motor Type: Brushless
- OPM: 18,000
- Oscillation Arc: 1.6°
- Weight: 2.33 lbs
- Length: 11.2 inches
- Battery Included: No (Tool-only)
- LED Work Light: Yes
The 1.6° arc is narrower than Milwaukee®'s M18 at 3.4°, which means less aggressive cutting but more controlled, precise movement. It is a real advantage for finishing work and detailed cuts.
How Much Does It Cost?
The DeWALT® DCS354B ATOMIC 20V MAX Oscillating Multi-Tool is priced at $83.99 for the tool-only version. That's a slight premium over the Milwaukee® M18 2626-20, but the brushless motor and LED light help justify the difference.
DeWALT® DCS356C1 20V MAX XR Oscillating Multi-Tool
The DCS356C1 is the only oscillating multi-tool that comes with batteries, charger, and a bag.
The DCS356C1 is DeWALT®'s premium oscillating multi-tool, sold as a complete kit with one 20V 1.5Ah battery, a charger, and a tool bag. The XR designation puts it at the top of DeWALT®'s performance tier, built for users who push their tools hard and need the reliability to match.
Key Specs
- Voltage: 20V MAX XR
- Motor Type: Brushless
- OPM: 20,000
- Oscillation Arc: 1.6°
- Weight: 2.33 lbs (tool); 5.7 lbs (full kit with battery, charger, and bag)
- Speed Settings: 3
- Included: Battery (1.5Ah), Charger, Tool Bag
- Power Features: LED Work Light, Variable Speed, 3-Speed Selector
How Much Does It Cost?
The DeWALT® DCS356C1 20V MAX XR kit is priced at $137.99, making it the most expensive option in this comparison. However, it's the only model here that includes a battery and charger. So, if you're starting fresh without any 20V MAX batteries, the effective cost difference shrinks considerably.
Milwaukee® vs DeWALT® Oscillating Multi-Tools: How Do They Compare?
With both lineups on the table, here's how they actually compare. Three areas matter most: raw speed, ergonomics, and whether your existing blades will fit.
Speed & Power Output
Milwaukee®’s M18 2626-20 runs 11,000–18,000 OPM with Constant Power Technology, holding speed when resistance climbs. That helps when cutting dense or layered materials.
DeWALT®'s DCS354B ATOMIC stays at 18,000 OPM, while the DCS356C1 XR hits 20,000 OPM across three speed settings. DeWALT® wins at peak speed, but Milwaukee® delivers steadier output under load. The M12 also hits 20,000 OPM, impressive for 12V but best for lighter tasks.
Weight, Size, & Ergonomics
The Milwaukee® M12 2426-20 is lightest at 2.05 lbs, with the DeWALT® DCS354B close behind at 2.33 lbs. Both stay comfortable overhead or in tight spaces. The Milwaukee® M18 weighs 3.38 lbs, manageable but noticeable on long sessions.
The DCS356C1 XR weighs 2.33 lbs (5.7 lbs as a full kit), comparable to the DCS354B. If ergonomics matter most, pick the DCS354B or M12.
Accessory Compatibility
Both use quick-change systems for tool-free blade swaps. DeWALT® advertises compatibility with most accessory brands, and Milwaukee®'s tool-free blade change with universal adapter accepts aftermarket and OEM blades. Both fit standard universal oscillating accessories, so your blade library shouldn't be a dealbreaker.

How Should You Choose an Oscillating Multi-Tool?
The right oscillating multi-tool comes down to four honest questions:
- What voltage system are you already running? If you own Milwaukee® M18 batteries, the 2626-20 is a no-brainer: you're not buying a new battery ecosystem. Same logic applies if you're already in the DeWALT® 20V MAX family.
- How important is runtime to you? If you're doing long sessions without access to a charger, the brushless DeWALT® models will outlast the brushed Milwaukee® options by a meaningful margin.
- Do you need precision or speed? DeWALT®'s tighter oscillation arc is purpose-built for controlled, detailed cuts. Milwaukee®'s wider 3.2°–3.4° arc on the M18 is built for fast, aggressive material removal.
- Are you buying a tool only, or do you need a complete kit? If you're starting from zero, the DeWALT® DCS356C1 kit at $137.99 (which includes everything you need) may actually save you money compared to buying the tool and battery separately.

Frequently Asked Questions (FAQs)
Is Milwaukee® or DeWALT® better for oscillating multi-tools?
Neither brand is universally better. It depends on your use case.
Milwaukee®'s M18 2626-20 wins for sustained power under load thanks to Constant Power Technology, making it stronger for heavy cutting. DeWALT®'s brushless motors in the DCS354B and DCS356C1 XR deliver better efficiency and longer runtime.

Can I use Milwaukee® blades on a DeWALT® oscillating tool?
Yes, in most cases. Both brands use accessory systems compatible with universal-fit blades. DeWALT® advertises compatibility with most accessory brands, and Milwaukee®'s tool-free blade change with universal adapter accepts aftermarket and OEM blades.
What is a good OPM range for an oscillating multi-tool?
Between 11,000 and 20,000 OPM covers most tasks. For finish work like sanding corners or cutting caulk, 11,000–14,000 OPM gives control. For aggressive cutting through wood, drywall, or adhesive, 18,000–20,000 OPM works faster.
