The Kreg Jig is a woodworking tool designed to create strong, hidden joints in various materials, primarily wood. It uses a simple drilling system that allows users to make pocket holes, which are angled holes that enable screws to be driven in at an angle. This technique provides a clean finish and enhances the strength of the joint, making it popular among both DIY enthusiasts and professional woodworkers. The Kreg Jig is user-friendly and often comes with adjustable settings to accommodate different wood thicknesses. It typically includes a drill bit, a stop collar, and a clamp to hold the workpiece securely. This tool is ideal for building furniture, cabinets, and other woodworking projects where aesthetics and durability are important.
