Abstract
A milling tool for thread-milling and boring has a milling region with thread-milling cutters disposed on thread-milling teeth, and bore-milling cutters disposed on an end face. The tool regions where the milling cutters are disposed are made of hard materials. The thread-milling cutters have a rake angle. The tool is successfully used to mill high-strength materials. The rake angle of the thread-milling cutters is zero or negative, and a coating of hard material is present in the region of the milling cutters. The combination of features including the use of hard material in the cutting region of the tool, the provision of a coating of hard material in the cutting region, and a zero or negative rake angle, enables use of the milling tool for thread-milling and boring with high-strength workpieces without problems and without experiencing high wear.
