Nailers, or tools used to drive nails into wood or other materials, have a few different synonyms depending on the context. One common synonym is "nail guns," which specifically refers to tools that use compressed air or electricity to drive nails quickly and efficiently. Another term often used is "nailing machines," which can refer to larger, industrial-grade equipment used in construction or manufacturing. "Nail setters" are also an option, referring to tools designed specifically for countersinking or finishing nails. Finally, "nail punches" are used to manually drive nails into surfaces without causing damage, and can also be considered a type of nailer.
