Is this drill good for concrete?

It handles light masonry such as brick and block. For repeated drilling into hard concrete, a corded hammer drill or a more powerful rotary hammer is the better tool.

Does it come with a battery and charger?

The 3602-20 is sold as a bare tool. Batteries and a charger are sold separately, so check whether you already own M18 packs.

How does it compare with Milwaukee's Fuel hammer drill?

The Fuel version has more torque and a more refined chuck and electronics. This model is lighter and simpler, and is enough for most drilling and driving around the house.

What can it drill through?

Wood, metal, plastic and light masonry with the right bits. The clutch and multiple gears help with driving screws and running holesaws.

Does it have a light?

Yes, a built-in LED illuminates the work area. It helps in cabinets and dim spaces but is not a substitute for a work light.

Is it worth it over a cheaper brushed drill?

The brushless motor gives longer runtime and less maintenance, and the M18 platform shares batteries with other Milwaukee tools. If you rarely drill, a cheaper brushed drill may be enough.
