Intended use
Core hole drills are used to produce holes with a defined diameter, which are required as a basis for subsequent thread cutting. They produce a dimensionally accurate core hole that corresponds to the required thread type and size. This enables a precise, resilient internal thread and reduces tool wear during thread cutting.
