An air-powered nail gun, also known as a nailer to some tradesmen, drives nails into wood or other types of material through the use of compressed air. While hammers were the preferred tool for centuries, the modern era has capitalized on advances in technology. You can use a nail gun in a wide range of projects, whether you are using finishing nails for installing baseboard or roofing nails to install plywood, for example.
Craftsmen use air guns for applying paint to materials. They can range in size from spray guns used in commercial applications such as when a painter is spraying a base coat throughout an entire house. Also use small enough tools like a pen for detail painting in art projects. Porter Cable air guns are the type used in construction. They're appropriate for residential or commercial applications.
Power sanders are a common tool among tradesmen, and air-powered sanders are just another type relying upon air rather than electricity to operate. Craftsmen use them to sand down wood, metal or other types of materials with varying grades of sandpaper. Depending on the project at hand, you can use a large or a small air sander attached to an air compressor.
Otherwise known as a torque gun or an impactor, impact wrenches are air-powered socket wrench tools that deliver an optimal amount of torque for loosening and tightening bolts and screws. They are most commonly used in the automotive industry, but they are also useful in major construction where high-rise buildings are held together by steel beams that need to be held together through bolts that are impossible to tighten sufficiently by hand.
