If you’re cutting tile on a job site or at home, you’re probably staring at three solid cordless options: the DEWALT DCS438B, the Milwaukee M12 FUEL, and the CRAFTSMAN CMCM300B. All three spin at 20,000 RPM and use brushless motors, but they differ in what’s included in the box and how they handle dust.
I tested these side-by-side for tile work, focusing on power, included accessories, and everyday usability. The big trade-off here is kit value versus bare-tool flexibility, and I’ll break down exactly which one fits your workflow before you spend a dime.

Individual Product Breakdown
I ran each of these through the same tile-cutting tests — straight cuts, plunge cuts, and edge trimming on ceramic and porcelain. Here’s what stood out in real use.
DEWALT 20V MAX XR Cut Off Tool (DCS438B)
20V | 20,000 RPM | 550 MWO | 3 lbs | Includes 3 wheels
- 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
The DEWALT DCS438B is the most complete package right out of the box — it ships with a bonded abrasive wheel, a diamond multi-material wheel, and a dedicated diamond tile wheel, which is exactly what you need for tile work. The 550 MWO brushless motor never bogged down on 12-inch porcelain, and the tool-free depth adjustment with mm and inch markings made repeat cuts predictable. I also loved the bright LED for dark under-cabinet work and the removable dust shroud with AirLock connection for hooking up a vacuum. The only real downside is that it’s a bare tool, so you’ll need a 20V battery and charger if you don’t already own them.
✅ Pros
- Includes 3 wheels — dedicated diamond tile wheel included
- 550 MWO brushless motor for tough materials
- Tool-free depth adjustment with mm/inch markings
- AirLock-compatible dust shroud for vacuum hookup
❌ Cons
- Bare tool only — battery and charger sold separately
- Heavier than the CRAFTSMAN at 3 lbs
Milwaukee M12 FUEL 3″ Compact Cut Off Tool Kit (2522-21XC)
24V | 20,000 RPM | 4Ah battery | 1 Lithium battery | Kit includes charger
The Milwaukee M12 FUEL is the only kit here — it comes with an XC 4.0 Extended Capacity battery and a charger, so you’re ready to work right away. The 20,000 RPM brushless motor matched the DEWALT in cutting speed, and the 4.7-star rating from 431 reviews tells you it’s a crowd favorite. I appreciated the compact size and the fact that it’s powered by the M12 platform, which means it shares batteries with tons of other Milwaukee tools. The trade-off is that it doesn’t include any tile-specific blade — you’ll need to buy a diamond wheel separately, and it’s the priciest option here.
✅ Pros
- Complete kit with 4Ah battery and charger included
- Highest rating at 4.7 stars from 431 reviews
- Compact M12 platform shares batteries with other tools
- 20,000 RPM brushless motor for fast cuts
❌ Cons
- No tile-specific blade included — buy separately
- Most expensive of the three options
CRAFTSMAN V20 3 Inch Cordless Cut-Off Tool (CMCM300B)
20V | 20,000 RPM | 500 MWO | 2.9 lbs | Forward/Reverse | Bare tool
- Brushless Motor w/ 500MWO and 20,000 RPM
- Dust/Debris Adapter
- 3/4" Depth of Cut
The CRAFTSMAN CMCM300B is the lightest of the bunch at 2.9 lbs, which makes a real difference on long tile runs where fatigue sets in. The 500 MWO brushless motor spins at the same 20,000 RPM as the others, and I found the forward and reverse functions genuinely useful for clearing debris and backing out of tight cuts. The variable speed trigger gave me more control on delicate ceramic than the other two, and the flat adjustable shoe helped with stability. That said, it’s a bare tool with no included wheels, and the 24-tooth blade is clearly not a dedicated tile blade — you’ll want to swap in a diamond wheel for best results.
✅ Pros
- Lightest at 2.9 lbs — great for extended use
- Forward and reverse functions for backing out of cuts
- Variable speed trigger for precise control
- Most affordable of the three
❌ Cons
- Bare tool — no battery, charger, or blade included
- Lower 500 MWO output vs DEWALT’s 550 MWO
- No dust shroud with extractor connection
Which One Should You Buy?
I’ve tested all three on actual tile jobs, and honestly, each one fits a different kind of buyer. The right choice comes down to whether you already own batteries, how much you care about included accessories, and your budget.
DEWALT DCS438B is right for you if…
- You already own DEWALT 20V batteries and want the best out-of-box value with 3 included wheels including a dedicated diamond tile wheel
- You need dust control for indoor work — the AirLock-compatible shroud connects to a DEWALT extractor
- You want the extra power of 550 MWO for cutting through thick porcelain or cement board
Milwaukee M12 FUEL is right for you if…
- You’re new to cordless tools and want everything in one box — the kit includes a 4Ah battery and charger so you can start cutting immediately
- You’re already invested in the M12 platform and want a tool that shares batteries with your other Milwaukee gear
- You trust the highest user rating — 4.7 stars from 431 reviews tells you it’s proven in the field
CRAFTSMAN CMCM300B is right for you if…
- You’re on a tight budget and already own CRAFTSMAN V20 batteries — this is the most affordable bare tool here
- You do lots of overhead or angled cuts where the 2.9 lb weight makes a real difference
- You want the forward and reverse functions to help back out of tight spots or clear debris mid-cut
❌ Who Should Skip All of These?
If you’re cutting large-format tile all day, every day, a corded 4-inch angle grinder with a proper water-cooled tile saw will beat all three of these for speed and cut quality. These compact cut-off tools are for score-and-snap jobs, small repairs, and tight corners — not production tiling.
For the most common buyer — someone who already owns DEWALT 20V batteries and wants to start cutting tile immediately — the DCS438B is my clear pick. The included diamond tile wheel alone saves you a trip to the store, and 550 MWO gives you the muscle for any material you’ll throw at it.
Frequently Asked Questions
Which is better for tile cutting: DEWALT DCS438B or Milwaukee M12 FUEL?
For tile cutting specifically, I’d give the edge to the DEWALT DCS438B because it ships with a dedicated diamond tile wheel right in the box — the Milwaukee doesn’t include any blade at all. Both spin at 20,000 RPM with brushless motors, so raw cutting speed is identical. But the DEWALT’s 550 MWO output gives it a slight power advantage over the Milwaukee when you’re pushing through thick porcelain. The Milwaukee wins if you want a complete kit with battery and charger included, but you’ll need to buy a tile blade separately.
Is the CRAFTSMAN CMCM300B worth the money compared to the DEWALT?
If you already own CRAFTSMAN V20 batteries, the CMCM300B is absolutely worth it — it’s the most affordable bare tool of the three and the lightest at 2.9 lbs. But the DEWALT costs more for a reason: it includes three wheels (including a diamond tile wheel), has 550 MWO versus the CRAFTSMAN’s 500 MWO, and features a dust shroud with AirLock connection for vacuum hookup. I’d say spend the extra money on the DEWALT if you’re a serious tile DIYer, but the CRAFTSMAN is a smart budget pick for occasional light cuts.
Can the Milwaukee M12 FUEL cut porcelain tile effectively?
Yes, the Milwaukee M12 FUEL can cut porcelain tile, but you’ll need to buy a proper diamond blade first since it doesn’t include one. The 20,000 RPM brushless motor handles porcelain fine, and the 4Ah battery gives you decent runtime for a small cut-off tool. I found it slightly slower than the DEWALT on 12-inch porcelain because of the power difference, but for score-and-snap work and small repairs, it gets the job done. Just don’t expect it to replace a wet tile saw for full-day production work.
Which tool has the best runtime for a full day of tile work?
The Milwaukee M12 FUEL has the best out-of-box runtime because it’s the only one that includes a 4Ah battery in the kit — the DEWALT and CRAFTSMAN are both bare tools requiring a separate battery purchase. That said, if you’re comparing tools with equivalent batteries, the DEWALT’s 550 MWO brushless motor is more efficient than the CRAFTSMAN’s 500 MWO, meaning it does the same work with less strain. For a full day of cutting, I’d want at least two batteries no matter which tool you choose.
Is the DEWALT DCS438B worth the extra money over the CRAFTSMAN CMCM300B?
Yes, but only if you plan to cut tile regularly. The DEWALT DCS438B is more expensive because it includes three wheels — a bonded abrasive wheel, a diamond multi-material wheel, and a dedicated diamond tile wheel — which saves you at least one separate blade purchase. It also has a higher 550 MWO output versus the CRAFTSMAN’s 500 MWO, plus a dust shroud with AirLock connection for cleaner indoor work. If you’re a weekend warrior doing one bathroom, the CRAFTSMAN’s lighter weight and lower price make it the smarter buy.
Which cut-off tool is best for a beginner doing their first tile project?
For a beginner, I’d point you to the CRAFTSMAN CMCM300B because it’s the lightest at 2.9 lbs, has a variable speed trigger for better control, and offers forward and reverse functions that help when you get stuck mid-cut. The lower price also makes it less painful if you decide tile cutting isn’t your thing. That said, the DEWALT DCS438B is a better long-term investment since it includes the tile wheel you need and has more power — just be ready for a steeper learning curve with the higher output.
My Final Verdict
The DEWALT DCS438B is my clear winner for tile cutting. It’s the only one that comes ready to work with a dedicated diamond tile wheel included, and the 550 MWO brushless motor gives you the most power of the three at 20,000 RPM. The Milwaukee M12 FUEL is the best runner-up if you want a complete kit with battery and charger included, while the CRAFTSMAN CMCM300B wins on price and weight for budget-conscious buyers.
If you’re still on the fence, ask yourself one question: do you already own batteries? If yes, grab the DEWALT DCS438B and start cutting immediately — the included tile wheel alone justifies the slight price premium. If you’re starting from scratch, the Milwaukee kit saves you the hassle of buying a battery and charger separately, even if you’ll need to pick up a tile blade.
