What is the purpose of a drill centering tool and how does it aid in precision drilling?

A drill centering tool is used to accurately position a drill bit at the center of a workpiece before drilling. This tool helps ensure that the hole is drilled in the correct location and at the desired angle, resulting in precise and accurate drilling. By guiding the drill bit to the center of the workpiece, the centering tool helps prevent errors and improves the overall quality of the drilling process.
