What is a drill gauge?

A drill gauge is a tool used to measure the diameter of drill bits and holes. It typically features a series of slots or holes of varying sizes, allowing users to quickly identify the size of a drill bit by inserting it into the appropriate slot. Drill gauges are commonly made from metal or plastic and are essential for ensuring accurate drilling and matching drill bits to screws or other fasteners. They are widely used in woodworking, metalworking, and various manufacturing processes.
