Classic center drill with center point. Ground with 2 pre-cutters and a bit shaft E 6.3. For drilling in softwood without special quality and accuracy of the hole. However, significantly better results than with conventional designs due to the pre-cutters. Flat center drills are in our opinion not professional tools in principle and unsuitable for hardwood. It is better to use FAMAG cylinder head drills, especially the Bormax® WS/HM.
