Are these the same tool?

Yes. Both are the DEWALT DCS356 20V MAX brushless oscillating multi-tool with a 3-speed selector and Quick-Change accessory system. The difference is what comes in the box.

Which is the better deal at $99.00?

The A kit. It adds a 4.0 Ah battery and charger for the same $99.00 at The Home Depot as of November 4, 2026, and that battery alone costs more than the difference.

Do I need the kit if I already own DEWALT 20V tools?

No. If you have 20V MAX batteries and a charger, B gives you the same tool with two blades and a bag. Check that the listing really includes those before you buy.

Which is better for cutting drywall and trim?

Both cut the same. The 3-speed selector and variable-speed trigger let you slow down for drywall and trim, and the LED light helps in dark cabinets. Blade choice matters more than the kit.

How long does the battery last?

DEWALT rates the brushless motor at up to 57% more runtime than a brushed tool. Expect the 4.0 Ah pack to cover most trim and cutout jobs on one charge, with spare packs for heavy sanding.

Is the tool-only version worth the extra?

It is not extra at the moment. Both are $99.00 as of November 4, 2026, so the kit is the better value unless you specifically want the two blades and bag.

DEWALT 20V MAX 3-Speed Oscillating Tool Kit vs DEWALT 20V MAX XR Brushless Cordless Oscillating Multi-Tool (Tool Only)

Both listings are the same DEWALT DCS356 oscillating multi-tool, and both hit $99.00 at The Home Depot as of November 4, 2026. Buy the A kit if you need a battery and charger, since the 4.0 Ah pack alone is worth more than the price gap. Buy B only if you already own 20V MAX batteries and want the tool with two blades and a bag.
