Center Drill

Center drills, also known as spotting drills or centering drills, are specialized tools used in machining operations to create an initial hole or indentation at the precise center of a workpiece. These drills have a unique design with a short, rigid body and a pointed tip, which enables them to accurately mark the center point for subsequent drilling operations. Center drills are commonly used in metalworking applications, particularly in tasks such as drilling accurate holes for lathe centers or starting holes for larger twist drills.

The primary purpose of center drills is to provide a starting point for other drilling operations while ensuring precision and accuracy. By creating a small, shallow hole at the center of the workpiece, center drills help prevent larger drill bits from wandering or drifting off-center during drilling. This initial indentation also acts as a guide for the drill bit, minimizing the risk of it slipping or skidding on the surface of the material. Additionally, center drills aid in achieving concentricity and alignment in machined components, which is crucial for applications where precision is paramount, such as in aerospace or automotive manufacturing.
