A finish nailer is a type of power tool used in woodworking and construction to drive small nails, known as finish nails, into wood and other materials. It is designed for tasks that require a clean and precise finish, such as installing trim, molding, or cabinetry. Finish nailers can be powered by electricity, batteries, or compressed air, making them versatile for various projects. These tools typically have a magazine that holds multiple nails, allowing for quick and efficient work. Unlike larger nail guns, finish nailers use smaller gauge nails, which leave less visible holes, making them ideal for detailed work where appearance matters.
