A center drill bit is a type of drill bit that is specifically designed for drilling starter holes in a workpiece before using a larger drill bit. It is also commonly referred to as a center drill or combined drill and countersink. The main purpose of a center drill bit is to create a precise starting point for a drill to prevent it from wandering or slipping off center. This is particularly important when working with metal or other hard materials where accuracy is crucial. Center drill bits typically have a 60-degree angle at the tip, which helps to guide the drill into the material and create a clean and accurate hole. They are available in various sizes to accommodate different drilling needs. When using a center drill bit, it is important to ensure that the workpiece is securely clamped down to prevent any movement during drilling. The drill should be held straight and steady to maintain accuracy and avoid any damage to the drill bit or workpiece
