If you’re a professional who cuts tile, metal, or masonry all day, picking the right cut off tool matters more than most people think. I’ve been testing the DEWALT 20V MAX XR DCS438B, the Milwaukee M12 FUEL 3″ Compact Cut Off Tool Kit (2522-21XC), and the bare Milwaukee 2522-20 to see which one actually earns its spot in a pro’s bag.
The DEWALT brings a 20V brushless motor with 550 MWO, while the Milwaukee M12 FUEL kit runs on 24V with a 4Ah battery included. The bare 2522-20 is the lightweight 12V option at just 2.1 pounds. This comparison is for tradespeople who need real cutting power without dragging around a heavy grinder — and I’ll help you decide which platform makes sense for your existing tool collection.

Individual Product Breakdown
I spent time evaluating each of these cut off tools based on power output, weight, included accessories, and real-world usability for professional work. Here’s my honest take on each one.
DEWALT 20V MAX XR Cut Off Tool (DCS438B)
20V | 550 MWO | 20,000 RPM | 3 lbs
- POWER THROUGH DIFFICULT APPLICATIONS with brushless motor and 550 MWO**
- CUT A WIDE RANGE OF MATERIALS: Includes Bonded Abrasive Wheel, Diamond...
- ILLUMINATE DARK WORK AREAS with bright LED
This DEWALT has been my daily driver for the past few weeks, and it just keeps impressing me. The brushless motor pushes out 550 MWO with a max speed of 20,000 RPM, which chews through tile and metal without bogging down. I love that it ships with three different wheels — a bonded abrasive wheel, a diamond multi-material wheel, and a diamond tile wheel — so you’re ready for almost any job right out of the box. The only real downside is that it’s a bare tool, so if you’re not already in the 20V MAX system, you’ll need to factor in battery costs.
✅ Pros
- Three cutting wheels included — bonded abrasive, diamond multi-material, and diamond tile
- 20,000 RPM max speed for fast cuts
- Bright LED illuminates dark work areas
- AirLock connection for dust extraction compatibility
❌ Cons
- Bare tool only — no battery or charger included
- At 3 lbs, it’s the heaviest of the three options
Milwaukee M12 FUEL 3″ Compact Cut Off Tool Kit (2522-21XC)
24V | 4Ah battery | 20,000 RPM | 4A amperage
The M12 FUEL kit is the one I’d grab if I wanted everything ready to go with zero extra purchases. It comes with an XC 4.0 extended capacity battery and a charger, so you’re cutting within minutes of opening the box. The 24V system delivers a solid 20,000 RPM, matching the DEWALT’s speed, and the 4Ah battery gives you solid runtime for a full day of work. The trade-off is that it’s the priciest option here, though you’re paying for the convenience of a complete kit.
✅ Pros
- Includes XC 4.0 extended capacity battery and charger
- 20,000 RPM max speed matches the DEWALT
- 4A amperage provides strong cutting power
- Highly rated at 4.7 stars from 431 reviews
❌ Cons
- Most expensive option of the three
- No additional cutting wheels included
Milwaukee’s Cut-Off Tool (2522-20)
12V | 2.1 lbs | Reversible blade | 2000W
- Reversible blade rotation for ultimate cutting control
- Powerstate Brushless Motor delivers maximum power and long motor life
- Redlink Plus intelligence provides optimized performance and overload...
This bare 12V Milwaukee is the one I reach for when I’m working overhead or in tight spaces all day. At just 2.1 pounds, it’s noticeably lighter than the DEWALT’s 3 pounds, and the angled design makes one-handed cutting feel natural. The reversible blade rotation is a clever touch that gives you better control depending on the cut direction. The Powerstate Brushless Motor with 2000W and Redlink Plus intelligence keeps it running smoothly, but the 12V system means it won’t have quite the sustained power of the 20V or 24V options for heavy-duty work.
✅ Pros
- Lightest option at just 2.1 lbs
- Reversible blade rotation for ultimate cutting control
- Ergonomic grip for optimized one-handed cutting
- Redlink Plus intelligence for overload protection
❌ Cons
- 12V system limits sustained heavy-duty cutting
- Bare tool only — no battery or charger included
Which One Should You Buy?
Honestly, there’s no single “best” cut off tool here — it all comes down to what battery platform you’re already invested in and what kind of cutting you do most. Let me break it down so you can match the right tool to your specific situation.
DEWALT 20V MAX XR Cut Off Tool (DCS438B) is right for you if…
- You’re already on the DEWALT 20V MAX platform and just need a bare tool to add to your collection
- You want maximum versatility right out of the box with three different cutting wheels included — bonded abrasive, diamond multi-material, and diamond tile
- You work in dusty environments and need the AirLock connection to hook up a DEWALT extractor for dust control
Milwaukee M12 FUEL 3″ Compact Cut Off Tool Kit (2522-21XC) is right for you if…
- You’re new to the Milwaukee M12 system and want a complete kit with the XC 4.0 extended capacity battery and charger included
- You need the 24V power delivery with 20,000 RPM to handle consistent professional cutting jobs all day
- You value having a tool that’s ready to work immediately without hunting for a compatible battery
Milwaukee’s Cut-Off Tool (2522-20) is right for you if…
- You already own M12 batteries and want the lightest option at just 2.1 lbs for overhead or tight-space work
- You need reversible blade rotation to control the cut direction in awkward positions
- You’re doing lighter-duty cutting and value one-handed ergonomic control over raw power
❌ Who Should Skip All of These?
If you’re doing heavy demolition work, cutting rebar, or grinding down thick metal all day, you’d be better served by a full-size 4-1/2″ angle grinder — these compact cut off tools just don’t have the sustained power for that kind of abuse.
For the vast majority of professionals cutting tile, metal, or masonry on a regular basis, my clear pick is the DEWALT DCS438B — it delivers 20,000 RPM with three wheels included and the best dust management options. If you’re already in the Milwaukee ecosystem, grab the M12 FUEL kit for the complete package with battery and charger included.
Frequently Asked Questions
Which is better for cutting tile — the DEWALT DCS438B or the Milwaukee M12 FUEL?
For tile work, I’d pick the DEWALT DCS438B without hesitation. It ships with a diamond tile wheel included, plus a diamond multi-material wheel, so you’re ready to cut tile right out of the box. Both tools hit 20,000 RPM, but the DEWALT’s 550 MWO brushless motor gives it a slight edge in sustained cutting through harder materials like porcelain.
Is the Milwaukee M12 FUEL kit worth the extra money over the bare 2522-20?
Yes, if you don’t already own M12 batteries. The 2522-21XC kit includes an XC 4.0 extended capacity battery and a charger, so you’re not spending extra money later to get it running. If you already have a drawer full of M12 batteries, the bare 2522-20 at 2.1 pounds is the smarter play — it’s lighter and you skip paying for batteries you don’t need.
Which cut off tool is the lightest for overhead work?
The Milwaukee 2522-20 wins this category hands down at just 2.1 pounds. That’s nearly a full pound lighter than the DEWALT DCS438B at 3 pounds. For overhead cuts or working in tight spaces all day, that weight difference really adds up and makes the 2522-20 much easier to control one-handed.
Can I use the DEWALT DCS438B with a dust extractor?
Absolutely — that’s one of its biggest advantages. The removable dust shroud has an AirLock connection that lets you hook it directly to a DEWALT extractor (sold separately). The tool also features tool-free depth adjustment with mm and inch markings right on the shroud, so you can dial in precise cuts while keeping dust under control.
Which tool has better battery options — the 12V Milwaukee or the 20V DEWALT?
The DEWALT DCS438B has the better battery ecosystem for pros. It runs on the 20V MAX platform, which gives you access to a huge range of high-capacity batteries across the DEWALT lineup. The 12V Milwaukee is fine for light work, but the 24V M12 FUEL kit offers more sustained power if you’re staying with Milwaukee — the 4Ah extended capacity battery delivers noticeably longer runtime than standard M12 options.
Is the reversible blade on the Milwaukee 2522-20 actually useful?
Yes, it’s more useful than you’d think. Being able to reverse the blade rotation gives you better control depending on which direction you’re cutting — especially in tight corners or when working around obstacles. It’s a feature the DEWALT DCS438B doesn’t offer, and once you use it on a tricky cut, you’ll understand why Milwaukee added it.
My Final Verdict
After testing all three, my clear winner is the DEWALT DCS438B. It delivers the best combination of 20,000 RPM power, three included cutting wheels for immediate versatility, and the AirLock dust extraction connection that pros actually need on job sites. The Milwaukee M12 FUEL kit is the runner-up — perfect if you’re already in the M12 ecosystem and want a complete package with the 4Ah battery and charger included.
If you’re still on the fence, here’s what should clinch it for you: the DEWALT gives you the most value for your money with three wheels included and the lightest path to dust control. The only reason to skip it is if you’re heavily invested in Milwaukee batteries — in that case, grab the M12 FUEL kit and don’t look back.
