These drills are designed to create a conical hole in a workpiece, providing a starting point for a standard twist drill. The conical shape helps to guide the twist drill accurately into the workpiece, ensuring that the hole is centered.</span></p>

The primary purpose of center drills is to create a starting point for the subsequent drilling operation. They help prevent the twist drill from wandering and ensure that the hole is accurately centered.
