- Research in Institut fuer Produktionstechnik und Spanende Werkzeugmaschinen (Institute of Production Engineering and Machine Tools) at Technische Hochschule Darmstadt (Germany) and also other institutes show that by drilling is recognized a development potential in increasing of process precision and reducing of cutting time. With key word complete machining with high speed cutting and at the same time with high precision, this research is conducted to obtain accurate data and to find the possible potential occurred in this process. HSC-Drilling is machining process, that is different to HSC-turning or milling. By HSC-Drilling the chip removal is more difficult than the others, especially at sack hole. For effective HSC-Drilling, tools with inner coolants are required. This tools need minimal pressure 50 bars, a lot of coolants, and fine filters. Therefore the experiments are carried out at two type of steels 42CrMo4V and 58CrMoV4 with carbide tools coated with diverse tools coating such as TiAlN, TiN, etc. As the conclusion resulting from these experiments is the tools coated with TiN (both as a single layer substrate and as multi layers substrate ) show the best performance.
