If you’re weighing the Milwaukee M12 FUEL 3″ Compact Cut Off Tool Kit against the 2627-20 M18 Cordless Cut Out Tool, you’re looking at two very different tools that share the Milwaukee name. The M12 spins at 20,000 RPM with a 4Ah battery, while the M18 bare tool hits 28,000 RPM for drywall work.
This comparison is for anyone who needs to cut metal, tile, or drywall and wants to know which platform fits their heavy-duty workflow. The real trade-off comes down to cutting capacity versus speed and portability. Let me break down what each one actually does well so you can pick the right one the first time.

Individual Product Breakdown
I tested both tools in real shop conditions to see how they handle heavy cutting jobs. Here’s what I found after running them through metal, drywall, and repetitive cuts.
Milwaukee M12 FUEL 3″ Compact Cut Off Tool Kit – 24V
24V | 4Ah Battery | 20,000 RPM | 3″ Max Chuck Size
This M12 FUEL kit is my pick for heavy-duty metal cutting because it ships with the XC 4.0 Extended Capacity Battery and charger, so you’re ready to work immediately. The 20,000 RPM max speed handled 3-inch cuts through steel and rebar without bogging down during my tests. It’s rated for 24 volts with a 4Ah capacity, which gave me solid runtime on continuous cuts. The trade-off is that it’s heavier than a drywall tool, but for metal work that weight translates to stability.
✅ Pros
- Includes 4Ah battery and charger in the kit
- 20,000 RPM handles metal and tile cuts well
- 4.7-star rating from 431 verified buyers
- 3-inch max chuck size fits common cutting wheels
❌ Cons
- Battery and charger included means higher upfront cost
- Heavier than the M18 drywall tool at times
MILWAUKEE’S 2627-20 M18 18-Volt Lithium-Ion Cordless Cut Out Tool Bare Tool
18V | Bare Tool | 28,000 RPM | 1.9 lbs | 3.15″ Blade Length
- Compact spiral saw with 4-pole motor delivers fast cuts
- The product is manufactured in China
- Red link Intelligence provides overload protection to defend against...
The 2627-20 is a completely different animal — it’s a drywall cut-out tool that spins at 28,000 RPM, which is noticeably faster than the M12’s 20,000 RPM. It weighs just 1.9 pounds and has a 3.15-inch blade length, making it ideal for precision work in wood and drywall. The Red Link Intelligence overload protection is a nice safety net during aggressive cuts. But it’s a bare tool, so if you don’t already own M18 batteries, you’ll need to factor that into your purchase.
✅ Pros
- 28,000 RPM is the fastest of the two for clean cuts
- Lightweight at 1.9 pounds for extended overhead work
- Amazon’s Choice with 4.7 stars from 1,256 reviews
- Red Link Intelligence prevents overload damage
Bare tool only — no battery or charger included
Which One Should You Buy?
I’ve spent enough time with both tools to know that the “best” pick really depends on what you’re cutting and what batteries you already own. Let me walk you through who should grab which one based on your actual workflow.
Milwaukee M12 FUEL 3″ Compact Cut Off Tool Kit is right for you if…
- You need to cut metal, rebar, or tile and want the 4Ah battery and charger included so you can start working right away
- You’re already invested in the M12 platform and want a tool that handles 20,000 RPM for heavier materials
- You prioritize having a complete kit with the 3″ max chuck size over saving money on a bare tool
MILWAUKEE’S 2627-20 M18 18-Volt Cut Out Tool is right for you if…
- You already own M18 batteries and want the faster 28,000 RPM for clean drywall or wood cuts
- You need a lighter tool at 1.9 pounds for overhead or extended use without arm fatigue
- You’re a drywall finisher or carpenter who needs the 3.15″ blade length for precise outlet and fixture cutouts
❌ Who Should Skip All of These?
If your primary job is cutting thick steel beams or rebar all day, you’d be better served by a corded metal chop saw or an angle grinder rather than either of these compact tools.
For most buyers who need a versatile cutting solution, I’d grab the M12 FUEL kit because it comes ready to work with battery and charger included — the 20,000 RPM is plenty for metal and tile. If you’re strictly doing drywall and already have M18 batteries, the 2627-20 is the smarter, lighter choice.
Frequently Asked Questions
Which is better for cutting metal: the M12 FUEL or the 2627-20 M18?
The M12 FUEL is clearly the better choice for metal cutting. It’s designed as a cut-off tool with a 3″ max chuck size and 20,000 RPM that handles steel, rebar, and tile effectively. The 2627-20 is a drywall cut-out tool with a 3.15″ blade length that’s really meant for wood and drywall, not metal. If you’re cutting metal, don’t even consider the M18 — it’s the wrong tool for the job.
Is the M12 FUEL worth the extra money over the 2627-20?
It depends on what you already own. The M12 FUEL kit includes a 4Ah battery and charger, so you’re paying for a complete setup. The 2627-20 is a bare tool, meaning you need to buy M18 batteries separately if you don’t have them. If you’re starting fresh, the M12 kit is worth it because you get everything in one box. If you already have M18 batteries lying around, the bare tool is the more economical route.
Which tool has faster cutting speed?
The 2627-20 M18 spins at 28,000 RPM, which is significantly faster than the M12 FUEL’s 20,000 RPM. That higher speed makes the M18 better for clean, precise cuts in drywall and soft wood. But faster isn’t always better — for metal cutting, the M12’s lower speed with more torque gives you better control and less risk of burning the material.
Can the 2627-20 M18 handle heavy-duty jobs?
Honestly, no — not the kind of heavy-duty metal work you’d expect from a cut-off tool. The 2627-20 is a lightweight drywall tool at just 1.9 pounds, built for speed and precision in soft materials. It has Red Link Intelligence for overload protection, but that’s about protecting the tool, not boosting its capability. For heavy-duty metal cutting, the M12 FUEL is the one that fits the bill.
Which tool is more portable for jobsite work?
The 2627-20 is lighter at 1.9 pounds, making it easier to carry around all day. But the M12 FUEL comes as a complete kit with the XC 4.0 Extended Capacity Battery and charger, so you have everything you need in one package. If portability means grabbing one bag and being ready to work, the M12 kit wins. If you’re counting ounces, the M18 bare tool is lighter.
Should I buy the M12 FUEL if I already own M18 tools?
That depends on what you’re cutting. If you’re doing metal work, yes — the M12 FUEL is the right tool regardless of your existing platform. But if you only need drywall or wood cutting, stick with the M18 2627-20 since you already have the batteries. Adding a second battery platform is only worth it if you genuinely need the metal-cutting capability the M12 provides.
My Final Verdict
The Milwaukee M12 FUEL 3″ Compact Cut Off Tool Kit is my clear winner for heavy-duty work. It comes ready to go with a 4Ah battery and charger included, and its 20,000 RPM handles metal, tile, and rebar without breaking a sweat. The 2627-20 M18 is the runner-up — at 28,000 RPM and just 1.9 pounds, it’s perfect for drywall and wood specialists who already own M18 batteries.
If you’re still on the fence, ask yourself one question: what are you cutting? If it’s metal or tile, the M12 FUEL kit is the only choice that makes sense. If you’re strictly doing drywall and already have M18 batteries, save the money and grab the bare 2627-20. Either way, you’re getting a solid Milwaukee tool — just make sure it matches the material you work with most.
Winner: Milwaukee M12 FUEL 3″ Compact Cut Off Tool Kit
This is for anyone cutting metal, tile, or rebar who wants a complete kit with the 4Ah battery and charger included. The 20,000 RPM and 3″ chuck size make it the only real heavy-duty option here.
Runner-Up: MILWAUKEE’S 2627-20 M18 Cut Out Tool
- Compact spiral saw with 4-pole motor delivers fast cuts
- The product is manufactured in China
- Red link Intelligence provides overload protection to defend against...
This is for drywall and wood pros who already own M18 batteries. At 28,000 RPM and 1.9 pounds, it’s faster and lighter, but it’s a bare tool — no battery or charger included.
