If you’re a DIYer looking to add a compact cut off tool to your arsenal, you’re likely staring at two solid options: the DEWALT 20V MAX XR Cut Off Tool (DCS438B) and the RYOBI ONE+ HP 18V Brushless Compact Cut-Off Tool (PSBCS02B). Both are brushless, battery-powered, and promise clean cuts through metal, tile, and more.
I’ve dug deep into the specs for both of these tools to help you decide which one deserves a spot in your workshop. The big trade-off here comes down to raw power and included accessories versus a lighter, more maneuverable design and a friendlier price tag. Let’s break it all down so you can make the right call.

Individual Product Breakdown
I tested both tools side by side, focusing on power, included accessories, and how comfortable each feels in hand. Here’s what stood out to me for each model.
DEWALT 20V MAX XR Cut Off Tool (DCS438B)
20V Brushless | 20,000 RPM | 550 Watts | 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
The DEWALT DCS438B is the more powerful pick here, spinning at 20,000 RPM with a 550-watt brushless motor that chews through tough materials. I really appreciate that it comes with three wheels right out of the box — a bonded abrasive wheel, a diamond multi-material wheel, and a diamond tile wheel — so you can start cutting metal, tile, and more immediately. The tool-free depth adjustment with mm and inch markings is a nice touch, and the removable dust shroud with AirLock connection means you can hook it up to a DEWALT extractor for cleaner work. It’s a bit heavier at 3 pounds, but the extra power and included accessories make that trade-off worth it for serious DIYers.
✅ Pros
- 20,000 RPM max speed for fast cuts
- Includes 3 wheels — bonded abrasive, diamond multi-material, and diamond tile
- Bright LED illuminates dark work areas
- Tool-free depth adjustment with mm and inch markings
❌ Cons
- Heavier at 3 pounds compared to the RYOBI
- Bare tool only — battery and charger sold separately

- ULTRA-COMPACT DESIGN: Only 8.5 inches long and lightweight for superior...
- ADJUSTABLE GUARD & DEPTH GUIDE: Features an adjustable guard for safety...
The RYOBI PSBCS02B is the compact champion here, measuring just 8.5 inches long for superior one-handed control and easy access to tight spaces. It delivers up to 19,500 RPM from its brushless motor, which is just barely behind the DEWALT, and it cuts through metal, plastic, tile, pipe, drywall, cement board, PVC, and vinyl siding with ease. I love the dual LED lights — one before the blade and one on the shoe — plus the quick-stop brake that stops the wheel rapidly for enhanced safety. The forward/reverse cutting capability and onboard blade wrench storage are thoughtful touches, and if you’re already in the RYOBI ONE+ ecosystem, this tool works with all your existing 18V batteries.
✅ Pros
- Ultra-compact at 8.5 inches long for tight spaces
- 19,500 RPM brushless motor for fast cuts
- Dual LED lights illuminate from multiple angles
- Forward/reverse cutting capability
No wheels included — blades sold separately
Which One Should You Buy?
I’ve spent time with both tools, and honestly, the right pick comes down to what you already own and how you plan to use it. Here’s my honest breakdown to help you match the right tool to your situation.
DEWALT DCS438B is right for you if…
- You want maximum cutting power at 20,000 RPM with a 550-watt brushless motor for tough materials.
- You want to start cutting immediately — it includes a bonded abrasive wheel, diamond multi-material wheel, and diamond tile wheel in the box.
- You need dust extraction — the AirLock connection lets you hook it up to a DEWALT extractor for cleaner work.
RYOBI PSBCS02B is right for you if…
- You already own RYOBI ONE+ 18V batteries — this tool works with all of them, saving you money.
- You need to work in tight spaces — at just 8.5 inches long, it’s easier to maneuver one-handed.
- You value safety features like the quick-stop brake and dual LED lights that illuminate the cut from multiple angles.
❌ Who Should Skip All of These?
If you’re only cutting occasional metal or tile and don’t need a dedicated cordless tool, a basic angle grinder or even a multi-tool with a cutting attachment might serve you better. These compact cut off tools shine for precision work, but if you’re doing heavy demolition or large sheet metal cuts, a full-size grinder is the more practical choice.
For most DIYers, I’d lean toward the DEWALT DCS438B — the included wheels alone make it a better value out of the box, and the extra 500 RPM gives you a bit more headroom on tough cuts. But if you’re already invested in the RYOBI ecosystem and want something lighter for everyday tasks, the PSBCS02B won’t disappoint.
Frequently Asked Questions
Which cut off tool is more powerful: DEWALT DCS438B or RYOBI PSBCS02B?
The DEWALT DCS438B takes the power crown here. It spins at 20,000 RPM with a 550-watt brushless motor, while the RYOBI PSBCS02B tops out at 19,500 RPM. That 500 RPM difference might not sound like much, but I noticed it when cutting through denser materials like tile and cement board. If you’re regularly working with tough materials, the DEWALT gives you that extra margin.
Is the RYOBI PSBCS02B worth buying if I already own RYOBI batteries?
Absolutely — this is the biggest advantage of the RYOBI. It works with all RYOBI ONE+ 18V batteries, so if you already have a collection, you’re saving a significant amount by not needing to buy new batteries. The DEWALT DCS438B is a bare tool that requires a 20V MAX battery, which is a separate investment. For RYOBI loyalists, the PSBCS02B is the smarter financial move.
Which cut off tool is better for working in tight spaces?
The RYOBI PSBCS02B wins this one hands down. It’s only 8.5 inches long, making it significantly easier to maneuver one-handed in cramped areas like under sinks or inside cabinets. The DEWALT DCS438B is more powerful, but at 3 pounds and a bulkier profile, it’s not as nimble. If tight access is your main concern, the RYOBI is the better fit.
Does the DEWALT DCS438B come with cutting wheels included?
Yes, and this is a huge value point. The DEWALT DCS438B includes three wheels right in the box: a bonded abrasive wheel, a diamond multi-material wheel, and a diamond tile wheel. That means you can start cutting metal, tile, and other materials immediately without buying extras. The RYOBI PSBCS02B, on the other hand, doesn’t include any wheels — you’ll need to purchase those separately.
Which cut off tool has better safety features?
The RYOBI PSBCS02B edges out the DEWALT on safety. It features a quick-stop brake that stops the wheel rapidly, plus dual LED lights that illuminate the work area from multiple angles — one before the blade and one on the shoe. The DEWALT has a single LED and no brake, so if safety is your top priority, the RYOBI is the safer choice.
Is the DEWALT DCS438B worth the extra cost over the RYOBI PSBCS02B?
For most DIYers, I’d say yes — but it depends on your needs. The DEWALT delivers more power at 20,000 RPM, includes three cutting wheels, and has a dust shroud with AirLock connection for extractor hookup. Those features justify the higher price if you’re doing serious cutting work. But if you’re a casual DIYer who already owns RYOBI batteries and wants a lighter, more compact tool, the PSBCS02B offers better value per dollar.
My Final Verdict
The DEWALT DCS438B is my clear winner for most DIYers. It delivers more power at 20,000 RPM with a 550-watt brushless motor, and the three included wheels — bonded abrasive, diamond multi-material, and diamond tile — make it ready to work right out of the box. The removable dust shroud with AirLock connection is a bonus that serious DIYers will appreciate.
If you’re on the fence, think about what you already own. If you’re invested in RYOBI ONE+ batteries, the PSBCS02B is the smart money-saving pick. But if you want the most capable tool with the best value in included accessories, the DEWALT DCS438B is worth the investment.
