Does this come with a battery and charger?

The unit ships as the drill body only. Battery and charger are sold separately to give you flexibility on voltage compatibility across your existing tool ecosystem.

What size bits does this accept?

Standard ½-inch chuck — fits all common drill bits, screwdriver bits, and spade bits. Tighten by hand or use a chuck key if included with your specific unit.

Can I use this for sustained work like metal drilling?

Built for light to medium tasks — fastening, basic drilling, and assembly. Heavy production work or continuous metal boring will drain the battery quickly. Runtime depends on battery capacity, which you'll select separately.
