ABSTRACT:
An adjustable boring bar is disclosed having a hollow case with an integral shank and a tool supporting nose receivable in the case. An adjusting pin is mounted on the case and threadably received in the nose such that it can be pivoted between adjusted positions, and precisely moved between lateral positions in the case. A draw pin in the case passes through a lateral opening in the nose for preventing removal of the nose from the case. A collar locks the draw pin in a locking position. The position of the tool can be adjusted longitudinally, transversely, and pivotally with respect to the shank.
