Intended use
Core drill bits are used to create holes of a specific diameter, which serve as the basis for subsequent thread cutting. They create a dimensionally accurate pilot hole that corresponds to the required thread type and size. This enables a precise, high-strength internal thread and reduces tool wear during thread cutting.
