Question

When there is no hole in the component, what type of piloting is employed.
​

Answer 1

Answer:

A pilot hole is a small hole drilled into a piece of construction material. Its purpose is a) to guide a larger drill to the appropriate location and ease the job of the larger drill, b) to allow for the insertion of another hole-making tool, such as a knockout punch, that will produce the final-sized hole, or c) to locate, guide, and provide clearance for a self-threading screw in wood or plastic to prevent damaging the material or breaking the screw.
