Jig drilling is a technique used to drill holes in a workpiece with accuracy and repeatability. A jig is a device that holds the workpiece in a fixed position and guides the drill bit. This ensures that the holes are drilled in the correct location and at the correct depth.

Jig drilling is often used in manufacturing to drill holes in large numbers of identical parts. It can also be used in woodworking and other DIY projects.

There are many different types of jigs for drilling, each designed for a specific purpose. Some common types of jigs include:

Centering jigs: These jigs hold the workpiece in a central position and prevent it from rotating. This is important for drilling holes that are perfectly centered.Angle jigs: These jigs allow you to drill holes at a specific angle. This is useful for drilling holes for hinges, screws, and other fasteners.Depth stop jigs: These jigs limit the depth of the hole that is drilled. This is important for preventing the drill bit from going too deep and damaging the workpiece.Template jigs: These jigs are used to drill holes that are located according to a template. This is useful for drilling holes for patterns and designs
