A finish nailer is a type of power tool used for driving nails into wood and other materials. It is commonly used in woodworking projects, such as installing trim, molding, and cabinetry. Finish nailers typically use smaller nails, known as finish nails, which create a less visible hole compared to larger nails or screws. These tools can be powered by electricity, batteries, or compressed air. Electric and battery-powered finish nailers offer portability and ease of use, while pneumatic models require an air compressor. Finish nailers are popular among both professional carpenters and DIY enthusiasts for their efficiency and precision.
