A Brad Nailer is a type of power tool used for fastening thin pieces of wood or trim. It uses small, thin nails called brads, which are typically 18-gauge, to create a strong hold without splitting the wood. This tool is commonly used in woodworking, cabinetry, and home improvement projects. Brad nailers can be powered by electricity, batteries, or compressed air. They are favored for their precision and ease of use, allowing for quick assembly of furniture or installation of moldings. Many professionals and DIY enthusiasts rely on brad nailers for their efficiency and clean finish.
