If you’re cutting tile, you’re probably staring at two solid options: the DEWALT 20V MAX XR Cut Off Tool (DCS438B) and the CRAFTSMAN V20 3 Inch Cordless Cut-Off Tool (CMCM300B). Both are bare tools that run on 20V batteries, and both spin at 20,000 RPM.
I’ve dug through the specs on both of these to help you decide which one fits your tile work best. The DEWALT brings more included wheels and a stronger 550 MWO motor, while the CRAFTSMAN adds a handy reverse function — let’s see which matters more for you.

Individual Product Breakdown
I spent time comparing these two cut-off tools spec by spec, focusing on what actually matters when you’re cutting tile all day. Here’s my honest take on each one after digging through the numbers.
DEWALT 20V MAX XR Cut Off Tool (DCS438B)
550 MWO Brushless | 20,000 RPM | 3 lbs | 3 included 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 more complete package right out of the box. It packs a 550 MWO brushless motor that spins at 20,000 RPM, and it comes with three wheels including a dedicated Diamond Tile Wheel, a Diamond Multi-Material Wheel, and a Bonded Abrasive Wheel. I really like the tool-free depth adjustment with mm and inch markings on the dust shroud, plus the AirLock connection for hooking up a DEWALT extractor. The LED light is a nice touch for dark work areas, though at 3 pounds it’s slightly heavier than the Craftsman. If you want one tool that’s ready for tile, masonry, and metal without buying extra accessories, this is the one.
✅ Pros
- 3 wheels included — tile, multi-material, and bonded abrasive
- Stronger 550 MWO brushless motor
- Tool-free depth adjustment with mm and inch markings
- Airlock connection for dust extractor compatibility
❌ Cons
- Slightly heavier at 3 lbs
- No forward/reverse function
- Higher price point than the Craftsman
CRAFTSMAN V20 3 Inch Cordless Cut-Off Tool (CMCM300B)
500 MWO Brushless | 20,000 RPM | 2.9 lbs | 3/4″ depth of cut
- Brushless Motor w/ 500MWO and 20,000 RPM
- Dust/Debris Adapter
- 3/4" Depth of Cut
The CRAFTSMAN CMCM300B is a solid lighter alternative at 2.9 pounds, and it brings a couple of unique tricks to the table. The forward and reverse functions are genuinely handy for clearing debris or working in tight spots, and the 3/4-inch depth of cut handles most tile jobs fine. It also has a variable speed trigger and an LED light with a dust port adapter, plus it’s Craftsman Versatrack compatible for easy wall storage. The 500 MWO brushless motor is slightly less powerful than the DEWALT’s 550 MWO, and it only comes as a bare tool with no included wheels. For someone who already owns Craftsman V20 batteries and wants a lighter tool with reverse capability, this is a smart pick.
✅ Pros
- Forward and reverse functions for better control
- Lighter at 2.9 lbs
- Variable speed trigger
- Craftsman Versatrack compatible
❌ Cons
- No included wheels — bare tool only
- Less powerful 500 MWO motor
- Only 129 customer reviews vs DEWALT’s 3,241
Which One Should You Buy?
Both of these cut-off tools will get the job done on tile, but the right pick really depends on what you already own and how you work. Let me break down who each one suits best.
DEWALT DCS438B is right for you if…
- You want to start cutting immediately — the 3 included wheels (including the Diamond Tile Wheel) mean you don’t need to buy anything extra
- You need maximum power for dense materials like porcelain or stone — the 550 MWO brushless motor is the stronger of the two
- You already own DEWALT 20V MAX batteries and want the AirLock dust extraction connection for cleaner indoor work
CRAFTSMAN CMCM300B is right for you if…
- You want the forward and reverse functions to help clear dust from the cut line or back out of a stuck kerf
- You’re already invested in the Craftsman V20 battery platform and want to save money on the bare tool
- You prefer a lighter tool at 2.9 lbs and want a variable speed trigger for more control on delicate tile surfaces
❌ Who Should Skip All of These?
If you’re cutting large format tile or doing heavy production work all day, a 3-inch cut-off tool might feel underpowered — you’d be better served by a larger 4-1/2 inch angle grinder with a tile blade. Also, if you don’t already own a compatible 20V battery, remember both of these are bare tools, so you’ll need to factor in battery costs.
For most DIYers and tile installers, I’d point you to the DEWALT DCS438B — the included wheel selection and stronger 550 MWO motor make it the better value right out of the box. But if you’re already on the Craftsman platform and want reverse functionality, the CMCM300B is a perfectly capable budget-friendly choice.
Frequently Asked Questions
Which is better for tile cutting: the DEWALT DCS438B or the CRAFTSMAN CMCM300B?
For tile cutting specifically, I’d give the edge to the DEWALT DCS438B. It comes with a dedicated Diamond Tile Wheel included in the box, plus a Diamond Multi-Material Wheel, so you’re ready to cut ceramic and porcelain immediately. The Craftsman CMCM300B is a bare tool only, meaning you’ll need to buy a tile blade separately. The DEWALT’s 550 MWO brushless motor also gives it a bit more cutting power than the Craftsman’s 500 MWO motor.
Is the DEWALT DCS438B worth the extra money over the CRAFTSMAN CMCM300B?
In my opinion, yes — but it depends on your situation. The DEWALT costs more upfront, but you’re getting three wheels (bonded abrasive, diamond multi-material, and diamond tile) plus a tool-free depth adjustment with mm and inch markings. If you’re starting from scratch, those included accessories easily justify the price difference. However, if you already own Craftsman V20 batteries and need to save money, the CMCM300B at its lower price point is still a capable tool for lighter tile work.
Does the CRAFTSMAN CMCM300B have any features the DEWALT DCS438B doesn’t?
Yes, the Craftsman has two notable features the DEWALT lacks. First, it offers forward and reverse functions, which is genuinely useful for clearing debris from the cut line or backing out of a tight spot. Second, it has a variable speed trigger for more control on delicate surfaces. The DEWALT does have an LED light and AirLock dust extraction connection, but it runs at a fixed 20,000 RPM with no reverse option.
Which tool is lighter and easier to handle for extended tile work?
The CRAFTSMAN CMCM300B is slightly lighter at 2.9 pounds compared to the DEWALT’s 3 pounds. That difference is small on paper, but over a full day of cutting tile, it can add up. The Craftsman also has a more compact profile at 5.55″L x 5.04″W x 10.04″H, which makes it a bit easier to maneuver in tight spaces. That said, the DEWALT’s better dust shroud with AirLock connection might be worth the extra weight if you’re working indoors.
Are both tools compatible with 20V batteries from their respective brands?
Yes, both are bare tools that run on their brand’s 20V battery platform. The DEWALT DCS438B works with DEWALT 20V MAX batteries, while the CRAFTSMAN CMCM300B uses Craftsman V20 batteries. Neither includes a battery or charger in the box, so you’ll need to factor that into your purchase if you’re not already invested in one of these platforms. The DEWALT has a 1-year manufacturer warranty, while the Craftsman includes a limited warranty.
Which tool has better dust management for indoor tile cutting?
The DEWALT DCS438B clearly wins on dust management. It comes with a removable dust shroud featuring an AirLock connection, which lets you hook it up to a DEWALT extractor (sold separately) for near-dust-free cutting. The Craftsman has a dust port adapter and LED light, but it doesn’t offer the same integrated extraction system. If you’re cutting tile inside a finished space, the DEWALT’s dust control is a significant advantage.
My Final Verdict
The DEWALT DCS438B is my clear winner for tile cutting. Its 550 MWO brushless motor delivers more cutting power than the Craftsman’s 500 MWO, and the three included wheels — including a dedicated Diamond Tile Wheel — mean you’re ready to work immediately without buying extra accessories. The AirLock dust extraction connection is another major advantage for indoor projects.
If you’re on the fence, think about this: the DEWALT’s included wheel selection alone bridges the price gap with the Craftsman. But if you already own Craftsman V20 batteries and want the reverse function for tight spots, the CMCM300B is still a solid, lighter alternative at 2.9 pounds.
Winner: DEWALT DCS438B
- 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
Best for anyone who wants a complete tile-cutting setup out of the box. The 550 MWO motor and three included wheels make it the better value overall.
Runner-Up: CRAFTSMAN CMCM300B
- Brushless Motor w/ 500MWO and 20,000 RPM
- Dust/Debris Adapter
- 3/4" Depth of Cut
Best for Craftsman V20 battery owners who want a lighter tool with forward/reverse functions and a variable speed trigger. Just budget for a tile blade.
