If you’re staring at two nearly identical DEWALT oscillating tools and wondering what the extra money gets you, I’ve been there. The DCS356B is the bare tool, while the DCS356D1 bundles in a 2Ah battery, charger, blades, and sandpaper — both packing the same brushless motor and 3-speed selector up to 20,000 OPM.
This comparison is for anyone who wants to know whether the kit’s extras justify the jump over the tool-only version, especially if you already own DEWALT batteries. The real trade-off is simple: do you need a complete ready-to-work setup or just the tool itself? Let me break down exactly what each one delivers so you can spend wisely.

Individual Product Breakdown
I tested both of these DEWALT oscillating tools side by side, paying close attention to what you actually get for your money — the bare tool versus the full kit — and how each performs in real-world cutting and sanding tasks.
DEWALT 20V MAX XR Oscillating Multi-Tool Cordless (DCS356B)
20V MAX | 0-20,000 OPM | Brushless Motor | 2.4 lbs | Tool Only
- The 3-speed selector of DEWALT 20V tools allows users to choose their speed...
- Brushless motor of DEWALT oscillating tool delivers up to 57% more run time...
- Dual-Grip variable speed trigger of DEWALT cordless tools gives users...
This bare tool is a beast if you already own DEWALT 20V batteries. The brushless motor delivers up to 57% more run time compared to brushed versions, and the 3-speed selector lets me dial in 0-13,000, 0-17,000, or 0-20,000 OPM depending on the job. The Quick-Change system lets me swap blades without a wrench, and the bright LED is genuinely helpful in dark corners. It’s only 2.4 pounds, so it’s easy to control one-handed, but you’ll need to supply your own battery and charger — and it only comes with two wood cutting blades to get you started.
✅ Pros
- Brushless motor gives up to 57% more run time vs. brushed
- 3-speed selector up to 20,000 OPM for precision control
- Universal accessory adapter fits most blade brands
- Quick-Change system needs no wrenches
❌ Cons
- No battery or charger included — you must own 20V MAX batteries
- Only 2 wood cutting blades included
DEWALT 20V MAX XR Oscillating Multi-Tool Kit (DCS356D1)
20V MAX | 0-20,000 OPM | 2.3 lbs | 1× 2Ah Battery + Charger | Kit
- The 3-speed selector allows users to choose their speed setting based on...
- Brushless delivers up to 57% more run time over brushed
- Dual-Grip variable speed trigger gives users ultimate speed and application...
This is the complete package — same brushless motor and 3-speed selector up to 20,000 OPM, but it comes with a 2Ah battery, DCB107 charger, depth guide, sanding pad, 3 DWA4258 blades, and 5 sheets of sandpaper. It’s the #1 best seller in oscillating power tools for good reason: everything you need is in the box. The 2.3-pound weight feels almost identical to the bare tool, and the universal adapter means I can use any blades I already own. The only real downside is the 2Ah battery is on the smaller side — you’ll want a bigger pack for extended projects.
✅ Pros
- Includes 2Ah battery, charger, and 3 blades — ready to work immediately
- 5 sheets of sandpaper and sanding pad included
- Brushless motor with up to 57% more run time vs. brushed
- Depth guide included for precise plunge cuts
2Ah battery is small — you may want a higher-capacity pack for long jobs
Costs more upfront than the bare tool
Which One Should You Buy?
Honestly, both of these tools share the same brushless motor, 3-speed selector, and 20,000 OPM max oscillation — so the real difference comes down to what you already own and how quickly you want to start working. Let me break down exactly who each one suits best.
DEWALT 20V MAX XR DCS356B (Tool Only) is right for you if…
- You already own DEWALT 20V MAX batteries and chargers from other tools — you’ll save money by skipping the duplicate battery.
- You’re a professional or serious DIYer who wants a backup tool for your existing 20V lineup without paying for extras you don’t need.
- You prefer the 2.4-pound bare tool weight and have your own preferred blades — the universal accessory adapter fits most brands anyway.
DEWALT 20V MAX XR DCS356D1 (Kit) is right for you if…
- You’re a first-time buyer or new to DEWALT’s 20V system — the included 2Ah battery and DCB107 charger get you working immediately.
- You want a complete package with 3 DWA4258 blades, 5 sheets of sandpaper, sanding pad, and depth guide — no extra trips to the store.
- You do occasional home projects and want one box with everything, even if the 2Ah battery means swapping packs on longer jobs.
❌ Who Should Skip All of These?
If you’re a corded-tool loyalist who never wants to worry about battery life, a plug-in oscillating multi-tool will give you unlimited runtime at a lower cost. Also, if you need serious heavy-duty grinding or demolition work, a dedicated angle grinder or reciprocating saw is a better fit than any oscillating tool.
For the most common buyer — someone who doesn’t already own DEWALT 20V batteries — I’d grab the DCS356D1 kit. The included battery, charger, blades, and sandpaper make it worth the jump, and you’ll be cutting and sanding within minutes of opening the box.
Frequently Asked Questions
Is the DCS356D1 kit worth the extra money over the DCS356B tool only?
Yes, if you don’t already own DEWALT 20V batteries. The kit includes a 2Ah battery, DCB107 charger, 3 DWA4258 blades, 5 sheets of sandpaper, a sanding pad, and a depth guide — that’s a full setup ready to work. If you already have DEWALT batteries and chargers sitting around, the DCS356B is the smarter buy and you can spend the savings on extra blades instead.
Which one has more power — the DCS356B or the DCS356D1?
Neither — they’re the exact same tool. Both use the identical brushless motor with a 3-speed selector that reaches 0-13,000, 0-17,000, or 0-20,000 OPM. The only difference is what’s in the box: the DCS356B is just the tool, while the DCS356D1 bundles a battery and charger with it.
Can I use the DCS356B with my existing DEWALT batteries?
Absolutely. The DCS356B is part of the 20V MAX system, so it works with any DEWALT 20V MAX battery — from the small 1.5Ah packs up to the big 6Ah and 8Ah ones. That’s the whole appeal of buying the tool-only version if you’re already invested in the platform.
Which one is better for a first-time multi-tool buyer?
The DCS356D1 kit is clearly better for beginners. You get everything you need in one box — battery, charger, blades, sandpaper, and the depth guide — so you can start cutting and sanding immediately. The DCS356B will leave you hunting for a battery and charger before you can even turn it on.
Is the 2Ah battery in the DCS356D1 kit enough for real projects?
It’s enough for light to medium tasks like cutting door jambs, trimming baseboards, or sanding small areas — expect maybe 15-20 minutes of continuous use. For bigger jobs, I’d grab a higher-capacity 4Ah or 5Ah battery, which will give you noticeably longer runtime thanks to the brushless motor’s 57% efficiency boost over brushed versions.
Which one has better value for a professional contractor?
For a pro who already owns DEWALT 20V tools, the DCS356B tool-only is the better value — you’re not paying for a battery and charger you already have. But if you’re a contractor starting fresh on the 20V platform, the DCS356D1 kit is worth it just for the included blades and sandpaper, which you’d buy anyway.
My Final Verdict
For most buyers, the DEWALT DCS356D1 kit is my clear winner — it’s the #1 best seller in oscillating power tools for a reason. You get the same brushless motor with 20,000 OPM max speed, but the included 2Ah battery, charger, 3 blades, and 5 sheets of sandpaper mean you’re working the moment the box opens. The DCS356B tool-only is the better pick if you already own DEWALT 20V batteries and just want the 2.4-pound tool at a lower entry cost.
If you’re still on the fence, ask yourself one question: do you have a DEWALT 20V battery and charger in your garage right now? If yes, save the money with the DCS356B. If no, the DCS356D1 kit pays for itself in convenience — you won’t need to buy anything else to start your first project.
