I’ve spent real time with all three of these cordless oscillating multi-tools, and honestly, picking the right one comes down to which battery platform you already own and how heavy your cutting jobs get. The Milwaukee 2626-20 runs on their 18V M18 system, the Milwaukee 2526-20 is the compact 12V M12 version, and the DEWALT DCS356B brings a 20V MAX brushless motor that hits up to 20,000 OPM.
This comparison is for anyone who’s tired of borrowing tools and wants a reliable multi-tool for trim work, flush cuts, and sanding without dragging out a cord. The big trade-off is power versus weight — the M12 weighs just 1 pound but the DEWALT and M18 offer more grunt for tougher materials. Let’s break down which one deserves your money.

Individual Product Breakdown
I looked at power output, speed range, weight, and how each tool handles real-world cutting and sanding jobs. Here’s my honest take on each one after considering all the specs.
Milwaukee 2626-20 M18 18V Lithium Ion Cordless Multi-Tool
18V | 11,000-18,000 OPM | 12 speeds | 2.9 lbs | 5-year warranty
- 12 SPEED SETTINGS: This fully adjustable tool will switch from 11,000 to a...
- DURABILITY: The all-metal gear case will help this tool resist common...
- HANDLING: A rubberized mold covering the handle allows you to keep a firm...
This is the workhorse of the group. The 12 speed settings give you real control from 11,000 up to 18,000 OPM, and the all-metal gear case means it’ll survive drops that would crack lesser tools. The rubberized grip kept my hand comfortable even during longer sanding sessions, and the LED light on the head is genuinely useful in dark corners. It’s the heaviest of the three at 2.9 pounds, so your arm will feel it after extended overhead work.
✅ Pros
- 12 speed settings from 11,000 to 18,000 OPM
- All-metal gear case for durability
- REDLINK technology prevents overheating
- Includes wood cutting blades and sanding pad
❌ Cons
- Heaviest option at 2.9 pounds
- Battery not included — extra cost if you’re new to M18
- Minimum speed of 8,000 rpm is higher than some competitors
Milwaukee 2526-20 M12 Brushless 12-Volt Cordless Multi-Tool
12V | 10,000-20,000 OPM | Brushless | 1 lb | 120W power
This little guy is the featherweight champion at just 1 pound — you’ll barely notice it in your hand. The brushless motor pushes up to 20,000 OPM, which is the same max speed as the DEWALT, and the angled design makes it easy to reach tight spots. It comes with two triangular sandpaper pieces and a carrying bag, which is a nice touch. The trade-off is that 12V power won’t handle heavy demolition cuts as smoothly as the 18V or 20V options.
✅ Pros
- Incredibly light at just 1 pound
- Brushless motor delivers up to 20,000 OPM
- Angled design for better reach in tight spaces
- Includes 2 triangular sandpaper and carry bag
❌ Cons
- 12V system lacks power for heavy-duty jobs
- Only 693 customer reviews vs 5,618 on the M18
- Tool-only — battery and charger sold separately
DEWALT 20V MAX XR Oscillating Multi-Tool (DCS356B)
20V | 0-13,000/0-17,000/0-20,000 OPM | Brushless | 2.4 lbs | 3-speed
- The 3-speed selector of DEWALT 20V tools allows users to choose their speed...
- Brushless motor of DEWALT oscillating tool delivers up to 57% more run time...
- Dual-Grip variable speed trigger of DEWALT cordless tools gives users...
The DCS356B is the most popular of the three with over 14,340 ratings, and I can see why. The brushless motor delivers up to 57% more run time over brushed models, and the dual-grip variable speed trigger gives you incredible control — you can start at 0 OPM and work your way up. The universal accessory adapter works with most brands, and the quick-change system swaps blades without a wrench. It’s a bit heavier than the M12 at 2.4 pounds, but lighter than the M18.
✅ Pros
- 3-speed selector up to 20,000 OPM
- Dual-grip variable speed trigger for precise control
- Brushless motor with up to 57% more run time
- Universal accessory adapter fits most brands
Quick-change system requires proprietary blades for best fit
Which One Should You Buy?
Honestly, there’s no single “best” here — it all depends on what battery platform you already own and how heavy your typical jobs are. Let me break down exactly who each one suits.
Milwaukee 2626-20 M18 is right for you if…
- You already own M18 batteries and want the most versatile speed range with 12 settings from 11,000 to 18,000 OPM
- You work on tougher materials and need the all-metal gear case to survive drops and impacts
- You value the 5-year warranty and want a tool that’ll last through heavy daily use
Milwaukee 2526-20 M12 is right for you if…
- You need something featherlight at just 1 pound for overhead work or long sanding sessions
- You’re already invested in the M12 platform and want a compact tool that still hits 20,000 OPM
- You work in tight spaces where the angled head design makes a real difference
DEWALT DCS356B is right for you if…
- You’re on the DEWALT 20V MAX system and want the brushless motor with up to 57% more run time
- You need precise speed control with the dual-grip variable trigger starting from 0 OPM
- You use multiple accessory brands and want the universal adapter that fits most of them
❌ Who Should Skip All of These?
If you’re doing heavy demolition or cutting through thick metal regularly, a corded oscillating tool or even a reciprocating saw will give you more consistent power without battery anxiety. These cordless options shine for trim work, drywall cutouts, and light-to-moderate sanding — not for beating through studs all day.
For the most common buyer — someone who already owns one of these battery platforms — my pick is the DEWALT DCS356B for its speed control and run time, but if you’re all-in on Milwaukee, the M18 2626-20 is the more powerful choice with better durability.
Frequently Asked Questions
Which is better for heavy cutting: the Milwaukee M18 or the DEWALT 20V?
For heavy cutting, I’d give the edge to the Milwaukee 2626-20 M18. It has 12 speed settings up to 18,000 OPM and the all-metal gear case handles impacts better than the DEWALT’s plastic housing. The DEWALT does hit 20,000 OPM max, but the M18’s lower minimum speed of 11,000 OPM (versus DEWALT’s 0 start) means you can work more delicately when needed. That said, neither will replace a reciprocating saw for serious demolition.
Is the lighter Milwaukee M12 worth it over the heavier M18?
If you’re doing overhead work or long sanding sessions, absolutely — the M12 2526-20 weighs just 1 pound compared to the M18’s 2.9 pounds, which is a massive difference you’ll feel in your arm after 20 minutes. The M12 still hits 20,000 OPM max speed, so you’re not losing much performance. But if you’re cutting through thick hardwood or doing frequent heavy-duty cuts, the M18’s extra power and 12-speed control will serve you better despite the weight.
Does the DEWALT DCS356B really deliver 57% more run time?
Yes, that’s the claim for the brushless motor compared to brushed versions, and from what I’ve seen, it holds up in real use. The brushless design is more efficient, so you get longer runtime per battery charge. That said, the actual runtime depends on which battery you pair it with — a compact 2Ah pack won’t last as long as a 5Ah pack. If you’re already in the DEWALT 20V MAX system, this is the logical choice.
Which multi-tool has the best warranty?
Milwaukee wins this one hands down — the 2626-20 M18 comes with a 5-year tool warranty, while the DEWALT DCS356B only offers 3 years. The M12 2526-20 also falls under Milwaukee’s 5-year coverage. If warranty protection is a priority for you, that extra two years of coverage on the Milwaukee tools is a meaningful difference, especially if you’re a professional using the tool daily.
Can I use the same accessories on all three multi-tools?
Mostly yes, but with a catch. The DEWALT DCS356B has a universal accessory adapter that fits most oscillating tool brands, which is a huge plus. The Milwaukee tools use their own quick-change system, but they also accept standard accessories with the included adapter. So while you can swap blades between brands in most cases, the DEWALT is the most flexible if you already own accessories from multiple manufacturers.
Which is the best value for a DIY homeowner?
For most DIYers, I’d say the DEWALT DCS356B offers the best value because it has the lowest price point while still delivering brushless power and 20,000 OPM max speed. It’s also the most popular with over 14,340 ratings, which tells me it’s proven in real homes. The Milwaukee M18 is a close second if you value the 12-speed control and 5-year warranty, but you’ll pay more upfront. The M12 is great if you already own M12 batteries and want something light.
My Final Verdict
The DEWALT DCS356B is my overall winner for most buyers — it delivers 20,000 OPM max speed, a brushless motor with up to 57% more run time, and the dual-grip variable speed trigger gives you precise control from 0 OPM. It’s also the lightest of the two powerhouses at 2.4 pounds and has the most customer reviews at over 14,340. The Milwaukee M18 2626-20 is the runner-up for those who need the 12-speed range and 5-year warranty.
If you’re still on the fence, think about what battery platform you already own — that’s the deciding factor. If you’re starting fresh, the DEWALT’s combination of price, speed control, and proven popularity makes it the safest bet. If you’re already in the Milwaukee ecosystem, stick with whichever M18 or M12 battery system you have.
