Does the multi-tool need a wrench to change blades?

No. The DCS356 uses a Quick-Change lever, so most blades and pads swap by hand. A universal adaptor is included for accessories that need it.

Can the grinder use the same battery as the multi-tool?

Yes. Both tools run on DeWalt 20V MAX batteries, and the kit includes one 2.0Ah pack and a charger.

What can the multi-tool cut?

With the included wood-with-nails and fast-cut wood blades it handles trim, drywall and wood with embedded nails. The sanding pad and 25 sheets cover finishing work.

Is the grinder powerful enough for heavy grinding?

It reaches up to 9,000 RPM and is fine for light to medium grinding, cutting and metal prep. For long, continuous heavy work, a corded grinder holds up better.

What comes in the box?

The DCS356 multi-tool, DCG407 grinder, one 2.0Ah battery, charger, two wood blades, universal adaptor, sanding pad, 25 sandpaper sheets, accessory box, tool bag, side handle, clip-on guard, flanges and hex wrench.

Should I buy this kit or the tools separately?

The kit bundles both tools with a battery, charger and accessories, which suits someone starting on the 20V MAX platform. If you already own batteries and only need one tool, buying that tool alone makes more sense.
