A pocket hole jig is a woodworking tool designed to create angled holes for screws, allowing for strong and hidden joints between pieces of wood. It consists of a guide that holds the drill bit at a specific angle, ensuring precise and consistent holes. This technique is popular for furniture making and cabinetry, as it provides a clean finish without visible fasteners. Using a pocket hole jig simplifies the assembly process, making it easier for both beginners and experienced woodworkers. The jigs come in various sizes and styles, with some featuring adjustable settings for different wood thicknesses, enhancing versatility in woodworking projects.
