Nailers are tools used in construction and woodworking to drive nails into various materials, such as wood or drywall. They come in different types, including manual, pneumatic, and electric nailers, each designed for specific tasks. Nailers help speed up the nailing process, making it more efficient than using a hammer. Pneumatic nailers operate using compressed air, while electric nailers rely on electricity for power. Manual nailers, often called hand nailers, require physical force to drive the nail. Nailers are essential for tasks like framing, roofing, and furniture assembly, contributing to the overall quality and durability of the finished product.
