ABSTRACT:
A cutting tool holder includes an elongated holder body having a first end face through which passes a shaft receiving bore which extends longitudinally through the holder body to receive an elongated tool mounting shaft therein. The tool mounting shaft has an end collar at one end and is threaded at its opposite end to be releasably fastened to the holder body with the shaft extending through the holder body, and the tool mounting portion of the shaft protruding therefrom. A plurality of substantially disc-shaped shaft mounted members, including cutting tools and spacers, have opposite faces and are received in face-to-face relationship on the tool mounting portion of the shaft, between the end collar and the holder body end face. The end collar and each shaft-mounted member is provided with locator means comprising complementary-shaped recesses (holes or grooves) and protrusions (pins or bars) formed, respectively, on the adjacent faces thereof. With the shaft-mounted members properly positioned on the shaft, facing locator means interlock with each other and with the end collar to form a rigid, interlocked assembly of shaft-mounted members on the shaft. The shaft and associated shaft mounted members are tightened against the holder body in any selected rotational orientation thereto by a threaded shaft-engaging unit.
