Is the DCS354D1 the same tool as the DCS354B?

Yes. Both are the DCS354 brushless oscillating multi-tool with the same 18,000 OPM motor, 11.2 in length and 2.33 lb weight. The D1 adds a battery and charger.

Which is better if I already own DEWALT 20V batteries?

The DCS354B. You skip paying for a battery and charger you do not need, and it was $86.89 at eBay as of November 3, 2026.

How long does the 2 Ah battery last?

Expect short runtime under heavy load, such as long flush cuts in hardwood. A 2 Ah pack is best for trim work and short plunge cuts. Larger 20V MAX packs fit the same tool.

Is the kit worth the extra money?

Yes if you have no 20V MAX battery or charger, since buying those separately costs more than the roughly $13 gap. No if you already own the system.

Does either one take standard oscillating blades?

Yes. Both include a universal accessory adaptor, so most brands of oscillating blades fit, and the Quick-Change system swaps them without a wrench.

Which has better ratings?

The DCS354B shows 4.4 out of 5 from 120 ratings. The DCS354D1 shows 4.0 out of 5 from only 6 ratings, a much smaller sample.
