The DeWalt oscillating multi tool kit — most commonly sold as the DCS356D1 — bundles the brushless 20V MAX tool with a compact battery, charger, a two-blade starter set, a sanding pad, and a soft bag, and in use it delivers near-corded cutting speed with the obvious runtime trade-off of a battery pack. Below is exactly what comes in the box, what the three speed settings actually map to, and where the brushless cordless motor matches or trails the corded alternatives.

What’s in the box
Contents vary slightly by SKU and production year, but the standard retail kit includes:
- DCS356 oscillating multi-tool (no blade installed)
- One compact 20V MAX battery — historically a 2.0Ah pack, with some newer kits substituting a PowerStack pouch cell
- 20V MAX charger (refills the 2.0Ah pack in roughly 30–45 minutes)
- Universal accessory adapter
- Two starter blades — typically a wood-with-nails bi-metal and a fast wood-cutting blade
- Hook-and-loop sanding pad with assorted-grit sheets
- Soft contractor bag
Two practical notes: the included compact battery keeps the tool light but limits heavy cutting sessions, and the starter blades handle drywall and pine — not grout or hardened screws. If grout removal is your job, budget for a carbide-grit blade immediately. And if a listing shows no battery, you’re looking at the bare tool (DCS356B), not the kit.
Speed settings: what each position is for
The DCS356 pairs a three-position speed selector with a variable-speed dual-grip trigger, so the trigger feathers output inside the cap set by the selector. Matching the cap to the task is the single biggest factor in blade and pad life:
| Selector | OPM range | Best for | Why |
|---|---|---|---|
| 1 | 0–13,000 | Sanding, scraping, grout, metal | Low OPM keeps sanding pad hooks from melting and stops carbide teeth overheating on metal |
| 2 | 0–17,000 | General plunge cuts in wood and drywall, flush-cut trim | Best balance of cut speed and control for typical DIY work |
| 3 | 0–20,000 | Fast cuts in soft lumber, PVC, door jambs | Maximum strokes per second; only earns its keep in soft, non-abrasive material |
A common beginner mistake is leaving the selector on 3 for everything. On sanding pads and on blades that clip drywall screws, full speed roughly halves consumable life for no real gain.
The Quick-Change blade system in practice
DeWalt’s lever-operated Quick-Change mount needs no hex key: flip the lever up, pull the blade off the locating pins, press the new blade on at any of several clock positions, and snap the lever shut. The included universal adapter lets the tool run most open-back/OIS-style third-party blades — which matters because that’s where the real running cost lives. Bulk third-party wood blades run roughly $2–$3 each versus $10–$15 for a single premium bi-metal blade.
Ownership tip: the locating pins and adapter slot collect fine dust, especially after drywall work. If the lever turns gritty or a blade sits slightly skewed, blow the head out with compressed air and add one drop of light oil to the pin. A sticky Quick-Change is almost always contamination, not a worn part.
Brushless motor on plunge cuts and sanding — vs corded
The brushless motor’s real advantage isn’t peak speed — a 3-amp corded tool still spins faster on paper — it’s that the electronics hold OPM steadier when the blade bites and ease off under light loads to stretch runtime. In 3/4-inch oak door-jamb plunge cuts the tool keeps pace without the bogging you feel on brushed budget tools, and on sanding at speed 1–2 the finish quality is indistinguishable from a corded unit.
| DeWalt DCS356 kit (cordless) | DeWalt DWE315K (corded) | Bosch GOP40-30C (corded benchmark) | |
|---|---|---|---|
| Power source | 20V MAX battery (2.0Ah in most kits) | 3.0-amp cord | 4.0-amp cord |
| Max OPM | 20,000 (3 selectable caps) | ~22,000 (dial) | 20,000 (dial) |
| Working weight | ~2.4 lb bare / ~3.2 lb with compact pack | ~3.0 lb plus cord drag | ~3.3 lb plus cord drag |
| Blade system | Quick-Change lever + universal adapter | Quick-Change lever + adapter | StarlockPlus snap-in |
| Continuous runtime | ~25–45 min heavy cutting; ~60–80 min sanding per 2.0Ah | Unlimited | Unlimited |
| Typical street price | Kit ~$160–$200; bare ~$110–$130 | ~$100–$140 with accessory set | ~$180–$220 |
Translation: for punch-list work — cutting an outlet box, undercutting one jamb, sanding a patch — the cordless kit is faster in total time because there’s no cord to run. For a full afternoon of grout removal or a whole-house baseboard undercut, the corded DeWalt wins on runtime and price while the Bosch wins on vibration control. Neither touches the DCS356’s mobility.
Kit vs bare tool: the math
If you already own 20V MAX batteries, the bare DCS356B at roughly $110–$130 is the obvious buy. If this is your first tool on the platform, the kit math looks like this: bare tool ~$120 + 2.0Ah battery ~$70–$90 + charger ~$40–$60 + blade/sanding starter set ~$20 comes to roughly $250 assembled piecemeal, versus ~$170–$190 for the kit. The kit effectively discounts the battery and charger by 40–50%.
On cost per use: a DIYer running 30–40 oscillating-tool tasks a year pays roughly $4–$6 per use in year one at kit pricing, dropping under $1 by year three. Blades and sanding sheets — about $20–$40 a year for typical use — become the dominant cost long before the tool shows wear.
Which version fits your situation
| Your situation | Buy | Reason |
|---|---|---|
| Already own 20V MAX batteries | Bare DCS356B | Identical tool; the kit battery adds cost you don’t need |
| First cordless tool, mixed home projects | DCS356 kit (2.0Ah) | Cheapest way onto the platform; compact pack keeps it light |
| Remodeler cutting all day off-grid | Kit plus one 5.0Ah spare | A 5.0Ah pack roughly triples cutting runtime over the compact pack |
| Mostly bench/garage work near outlets, tight budget | Corded DWE315K | Unlimited runtime and lower entry price; no battery to age |
| Hours of grout removal or sanding in one session | Corded (DeWalt or Bosch) | Sustained load and runtime favor a cord |
| Tight cabinetry or installer work | Atomic DCS354 compact cordless | Shorter body reaches into carcasses the full-size head can’t |
What wears first: ownership realities
- Sanding pad hooks. The hook layer dies long before the tool, especially above speed 2. Replacement pads are cheap; buy paper in bulk assortments.
- Bi-metal blade teeth. One drywall screw at speed 3 can strip a wood blade — keep a carbide-grit or carbide-tooth blade for anything that isn’t clean lumber.
- Quick-Change pins. They rarely break, but dust makes blades sit crooked. Clean the head rather than forcing the lever.
- The compact battery. It’s the limiting component on cutting-heavy days, and cells age regardless — a weekend-use kit feels the same in five years, while a daily-use pack may need replacing around year three.
- The universal adapter. If you swap between DeWalt and third-party blades constantly, check it hasn’t crept loose — a rattling adapter is the most common “my tool got louder” complaint.
FAQ
Does the DeWalt oscillating multi tool kit accept other brands’ blades?
Yes. The Quick-Change mount plus included universal adapter runs most open-back/OIS-style blades, including inexpensive third-party multi-packs.
Is the kit worth it over the corded DWE315K?
If you value grab-and-go mobility or already own 20V MAX batteries, yes. If most of your work is long sessions near an outlet, the corded kit cuts similarly for less money and zero battery management.
Can it handle grout and thinset?
Yes, with a carbide-grit blade on speed 1–2. Grout is the heaviest consumable drain this tool has — budget blades and time accordingly.
Which batteries work in it?
Any DeWalt 20V MAX or FlexVolt pack. The bundled compact pack favors weight; a 5.0Ah favors runtime.
Bottom line: the DeWalt oscillating multi tool kit is the right buy for first-time 20V MAX users and anyone prioritizing mobility — the Quick-Change head and three-speed selector genuinely extend consumable life — while committed bench users and all-day grout jobs are still better served by a corded alternative.
