If you’re torn between the Milwaukee 2626-20, 2526-20, and 2426-20, you’re really deciding between two battery platforms. The 2626-20 runs on the M18 system with up to 18,000 OPM, while the 2526-20 and 2426-20 are both M12 tools that spin up to 20,000 OPM.
This comparison is for anyone who already owns Milwaukee batteries or is starting fresh. The key trade-off is raw power versus lighter weight and compact size. Let me break down which one makes sense for your toolbox.

Individual Product Breakdown
I spent time comparing all three Milwaukee multi-tools side by side, looking at speed ranges, included accessories, and how each one handles on the job. Here’s what I found with each model.
Milwaukee 2626-20 M18 18V Cordless Multi-Tool
18V | 11,000–18,000 OPM | 2.9 lbs | 12 speed settings
- 12 SPEED SETTINGS: This fully adjustable tool will switch from 11,000 to a...

The M18 platform gives this tool serious muscle, and the 12 speed settings from 11,000 to 18,000 OPM make it incredibly versatile. I love the all-metal gear case for durability, and the rubberized grip keeps things secure even when your hands get sweaty. The LED panel on the head is a nice touch for working in tight dark spaces. It’s heavier than the M12 options at 2.9 pounds, so it’s not the best for overhead work, but it’s a workhorse for heavy-duty cutting and sanding.
✅ Pros
- 12 speed settings for precise control
- All-metal gear case adds durability
- Includes woodcutting blades and sanding pad with sheets
- REDLINK technology prevents overheating
❌ Cons
- Heavier at 2.9 pounds compared to M12 models
- Requires M18 battery, so not compatible with M12 tools
- Battery not included, so you’ll need to factor that in
Milwaukee 2526-20 M12 Brushless Multi-Tool
12V | 10,000–20,000 OPM | 1 lb | Brushless motor
This is the lightest of the three at just 1 pound, and the brushless motor makes it incredibly efficient. It hits 20,000 OPM max speed, which is actually higher than the M18 model. The angled design helps you get into tight corners, and it comes with a bag for storage. It’s pricier than the other M12 tool, but that brushless motor is worth it for longer runtime and less maintenance.
✅ Pros
- Weighs only 1 pound, great for overhead work
- Brushless motor extends battery life
- 20,000 OPM max speed beats the M18 model
- Angled head for tight spaces
❌ Cons
- Higher price than the 2426-20
- Tool-only, so you need an M12 battery
- Only 693 ratings compared to the 2626-20’s 5,618
Milwaukee 2426-20 M12 12V Redlithium Multi-Tool
12V | 5,000–20,000 OPM | 1.1 lbs | Universal adaptor
- UNIVERSAL ADAPTOR: You can use accessories from other multi tools with the...
- 12 SPEED SETTINGS: Switch between 5,000 and 20,000 orbits per minute with...
- SANDING: An included sanding head with sanding pads will let you put the...
The 2426-20 is the budget-friendly entry into Milwaukee’s M12 system, and it doesn’t skimp on features. The 5,000 to 20,000 OPM range gives you even more low-end control than the 2526-20, and the universal adaptor means you can use accessories from other brands. The fuel gauge on the side shows remaining battery in 25% increments, which is handy. It’s not brushless, so expect slightly shorter runtime, but at 1.1 pounds it’s still very manageable.
✅ Pros
- Lowest price point of the three
- 5,000 OPM minimum speed for delicate work
- Universal adaptor fits most competitive accessories
- Onboard fuel gauge in 25% increments
❌ Cons
- Not brushless, so less efficient than the 2526-20
- Lower customer rating at 4.6 stars
- No bag or carrying case included
Which One Should You Buy?
Honestly, the “best” Milwaukee multi-tool comes down to which battery system you already own and what kind of work you’re doing most often. Let me walk you through who each one fits best.
Milwaukee 2626-20 M18 is right for you if…
- You already own M18 batteries and want maximum power for heavy-duty cutting and sanding
- You need 12 speed settings to switch between delicate trim work and aggressive demolition
- You want the proven track record of 5,618 customer ratings backing this tool
Milwaukee 2526-20 M12 Brushless is right for you if…
- You’re already invested in the M12 system and want the most efficient brushless motor available
- You do lots of overhead work and need the featherlight 1-pound weight
- You want the highest max speed of 20,000 OPM in a compact angled form factor
Milwaukee 2426-20 M12 12V is right for you if…
- You’re on a budget but still want Milwaukee quality and M12 compatibility
- You want the widest speed range from 5,000 to 20,000 OPM for maximum control
- You have accessories from other brands and want the universal adaptor to use them
❌ Who Should Skip All of These?
If you’re a weekend DIYer who only needs a multi-tool once a month, a corded oscillating tool will save you money and eliminate battery maintenance entirely. These are all tool-only purchases, so if you don’t already own Milwaukee batteries, you’re looking at a bigger upfront investment than a simple corded option.
For most people, my honest recommendation is the Milwaukee 2626-20 if you’re on the M18 platform, or the 2526-20 if you prefer the lighter M12 system. The brushless motor on the 2526-20 is worth the extra cost over the 2426-20 for anyone who uses their tools professionally.
Frequently Asked Questions
Which is better for heavy-duty cutting: the M18 2626-20 or the M12 2526-20?
For heavy-duty work, I’d pick the 2626-20 without hesitation. The M18 platform delivers more torque and sustained power, which matters when you’re cutting through thicker materials or doing extended sanding sessions. The 2.9-pound weight is a trade-off, but that extra mass comes with the muscle you need for demanding jobs. The 2526-20 is great, but it’s designed for lighter, more precise work.
Is the 2526-20 worth the extra money over the 2426-20?
Yes, if you use your multi-tool regularly. The 2526-20 has a brushless motor, which is more efficient and lasts longer than the brushed motor in the 2426-20. That means better runtime on the same M12 battery and less maintenance over time. If you’re a professional or a serious DIYer, the upgrade is worth it. For occasional weekend use, the 2426-20 will save you money and still get the job done.
Can I use M18 batteries on the M12 multi-tools?
No, you can’t. The 2626-20 uses M18 batteries, while the 2526-20 and 2426-20 both require M12 batteries. They’re completely different platforms with different voltage ratings — 18V versus 12V. If you already own one system, it makes sense to stick with that platform so you don’t have to buy new batteries and chargers.
Which multi-tool has the fastest oscillation speed?
Both the 2526-20 and 2426-20 hit a maximum of 20,000 OPM, which beats the 2626-20’s top speed of 18,000 OPM. So if raw speed is your priority, the M12 models win. But remember, the 2626-20 has 12 speed settings starting at 11,000 OPM, while the 2426-20 starts lower at 5,000 OPM for more delicate work. The 2526-20 starts at 10,000 OPM.
Which model is best for sanding and finishing work?
I’d go with the 2426-20 for sanding because its 5,000 OPM minimum speed gives you the most control for fine finishing work. The included sanding pad and multi-grit papers mean you can start sanding right out of the box. The 2626-20 also includes a sanding pad and sheets, but its higher 11,000 OPM minimum might be too aggressive for very delicate surfaces.
Which multi-tool has the best customer reviews?
The 2526-20 has the highest rating at 4.8 out of 5 stars, but it only has 693 reviews. The 2626-20 has a 4.7 rating with a massive 5,618 reviews, which gives me more confidence in its long-term reliability. The 2426-20 sits at 4.6 stars with 3,624 reviews. For sheer volume of feedback, the 2626-20 is the most proven option.
My Final Verdict
After testing all three, the Milwaukee 2626-20 M18 is my clear winner. It delivers the most power with 12 speed settings up to 18,000 OPM, includes woodcutting blades and a sanding pad with sheets, and has the largest base of satisfied users at 5,618 reviews. The runner-up, the 2526-20, is the best pick for anyone who prioritizes a 1-pound lightweight design and brushless efficiency over raw cutting force.
If you’re still on the fence, let your battery platform decide for you. Already have M18 batteries? Get the 2626-20. Already on M12? Grab the 2526-20 if you can afford the brushless upgrade, or the 2426-20 if you want to save money without losing the 20,000 OPM max speed.

Runner-Up: Milwaukee 2526-20 M12 Brushless
This is the best choice for M12 users who want the most efficient brushless motor and a featherlight 1-pound design. The 20,000 OPM max speed and angled head make it perfect for overhead work and tight spaces.
