A finish nailer is a type of power tool used for driving nails into wood and other materials. It is commonly used in woodworking and construction projects, particularly for attaching trim, molding, and cabinetry. Finish nailers typically use smaller nails, which leave less visible holes, making them ideal for detailed work. These tools can be powered by electricity, batteries, or compressed air. A pneumatic finish nailer uses air pressure to drive nails, while a cordless finish nailer operates on battery power for greater mobility. Finish nailers help speed up the nailing process and provide a cleaner finish compared to traditional hammers.
