The design of a center drill allows it to provide a stable starting point for drilling, preventing the drill bit from wandering or drifting off-center. This is particularly important in applications where high accuracy and concentricity are required, such as in the production of precision parts for machinery and tools. Center drills come in various sizes and configurations to accommodate different workpiece materials and drilling requirements. They are often used in combination with other cutting tools, such as twist drills, to achieve efficient and accurate hole drilling processes.
