A finish nailer is a type of power tool used in woodworking and construction to drive small nails, known as finish nails, into wood. It is designed for tasks that require a clean and precise finish, such as attaching trim, molding, or cabinetry. Unlike larger nail guns, a finish nailer uses smaller nails, typically ranging from 15 to 18 gauge, which leave minimal visible holes. These tools can be powered by electricity, batteries, or compressed air, making them versatile for various projects. Using a finish nailer helps speed up the installation process while ensuring a professional appearance. Proper safety precautions should be taken when operating a finish nailer to prevent accidents.
