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.

Abstract: A unique boring bar is disclosed which comprises a body having a generally radially extending formed through it at one end. A slide member is axially slidably positioned within the body throughbore and a standard cutting tool is secured to the slide member. In addition, one end of the slide member is externally threaded and threadably cooperates with an annular dial. The dial is locked against axial movement with respect to the body so that rotation of the dial axially displaces the slide member with its attached cutting tool.

Abstract: A bottom face mill having an elongated body that has a pair of clamping jaws formed on the front end thereof. The clamping jaws are spaced apart by a V-shaped notch which terminates at its inner end at the front end of a transverse, longitudinally extended slot. A triangular cutting tool is held in the V-shaped notch by a pair of retaining pins and a clamping screw which forces the clamping jaws into a releasable clamping engagement with the triangular cutting tool.
