Air nailers, also known as pneumatic nail guns, are tools that use compressed air to drive nails into various materials like wood and drywall. They are commonly used in construction and woodworking projects, providing a faster and more efficient alternative to manual nailing. Air nailers come in different types, including framing nailers, finish nailers, and brad nailers, each designed for specific tasks. To operate an air nailer, it requires a compatible air compressor that supplies the necessary pressure. Users can adjust the depth of the nail penetration for precision work. Safety features, such as a trigger lock, help prevent accidental firing, making air nailers a popular choice among both professionals and DIY enthusiasts.
