What voltage drill do I need?

12V drills are compact and light — best for tight spaces and light tasks. 18V/20V drills are the standard — they handle everything from drywall to deck screws. Higher voltage does not always mean more power — motor efficiency and torque ratings matter more than voltage alone.

Do I need a hammer drill?

Only if you drill into concrete or masonry. Hammer drills combine rotation with a percussive hammering action that chips through concrete. For wood, metal, and drywall, a standard drill/driver is sufficient and lighter. Many hammer drills let you disable the hammer function for normal drilling.
