Which is better for a first oscillating tool?

The kit (Product A). It includes a 4.0 Ah battery and charger, so you can use it the day it arrives. The ATOMIC is bare tool only, so you would need to buy a battery and charger separately.

Is the ATOMIC worth it if I already own DeWalt 20V batteries?

Yes. It has the same brushless motor and Quick-Change blade system, and at $85.00 at eBay as of November 4, 2026 it is the cheaper way in if you already have power.

Does the 3-speed selector matter?

It helps. Fixed settings make it easier to repeat a cut or sanding pass, while the ATOMIC relies on the variable speed trigger alone. For one-off cuts the difference is small.

Which one lasts longer?

Both use brushless motors rated for up to 57% more run time than brushed tools, so motor life should be similar. The kit's included 4.0 Ah battery adds a wear item the bare tool does not have.

How much cheaper is the ATOMIC?

$14 less as of November 4, 2026: $85.00 at eBay versus $99.00 at The Home Depot for the kit. Once you add a battery and charger, the kit is usually the better deal.

Do they use the same blades?

Yes. Both have the Quick-Change system and a universal adapter, so most oscillating tool blades fit either one.
