ABSTRACT:
A boring bar has a longitudinal axis, with a steel head section having a cutting insert displaced from the longitudinal axis. In one embodiment, a cemented carbide section is joined directly thereto. In another embodiment, a intermediate section includes a devibrator body. The respective sections are joined by a centrally positioned drawbar threadedly inserted into the head section for maintaining a compressive force at the specifically configured connection between the axially aligned sections.
