A screw gun is a power tool designed specifically for driving screws quickly and efficiently. It typically features a rotating bit that can be adjusted for different screw sizes and types. Screw guns are commonly used in construction and woodworking, making tasks like installing drywall or assembling furniture much easier. Unlike a standard drill, a screw gun often has a depth adjustment feature that allows users to control how deep the screw is driven. This ensures consistent results and prevents damage to the material being worked on. Many screw guns are compatible with various attachments, enhancing their versatility for different projects.
