§ FAQ

What batteries come with the DCG400S2?

The DCG400S2 includes two DCBP320 20V MAX* XR® 3.5 Ah batteries and a DCB118 charger, giving extended runtime for sustained grinding without stopping to recharge.

What disc size does the DCG400S2 use?

The DCG400S2 uses 4-in. wheels, the same compact disc format as the DCG400B bare tool. This allows grinding in tight spaces where larger 4.5-in. grinders cannot reach.

Is the grinder in the DCG400S2 kit the same as the DCG400B?

Yes. The DCG400S2 kit contains the same DCG400 grinder as the DCG400B bare tool. The kit simply adds batteries, charger, flanges, and a storage bag.

Does the DCG400S2 include anti-kickback protection?

Yes. The DCG400 grinder included in the kit has DEWALT's ANTI-ROTATION System, which detects bind-up events and stops the wheel to reduce reactionary torque.

Can I use 20V MAX* XR® batteries from other DEWALT tools with the DCG400S2?

Yes. The DCG400 grinder is compatible with the full DEWALT 20V MAX* battery ecosystem, including all XR® and standard 20V MAX* batteries.

What is the warranty on the DCG400S2?

The DCG400S2 tool carries DEWALT's 3-year limited warranty. Batteries and charger are covered under DEWALT's standard battery warranty.
