External broaching tool device

摘要

In an external broaching tool device for producing half-bores with a broaching tool holder and a broaching tool secured thereto and having raker teeth with cutting edges, said cutting edges of the raker teeth are adjusted at an angle other than 90 DEG in the direction of extent and longitudinal direction of the broaching tool. This arrangement prevents vibrations in the tool-device-machine system and ensures a uniform cutting force. In particular, the broaching tool is designed having an circular cross-section and is provided with cutting edges running around helically in the manner of a tapering thread.
