Air-powered brad nailers drive 18 ga. brads in lightweight finishing applications in cabinetry, construction, and woodworking where the appearance of nail heads should be minimized. Brad nailers drive smaller nails than finish nailers and larger nails than pin nailers. Air-powered nailers are typically lighter than cordless tools to help reduce operator fatigue during extended use. They also have fewer moving parts, so they tend to run cooler and have a longer lifespan.
