ABSTRACT:
A turning tool for use in metal machining having a holder with a first recess for receiving an insert carrier therein. The insert carrier has a second recess for receiving a cutting insert therein. The insert carrier has a planar base face and a generally semicylindrical supporting surface engaging a corresponding semicylindrical support surface in the first recess on the holder. Holding screws are provided for securing the insert carrier to the holder and for securing the cutting insert to the insert carrier. The semicylindrical support surface on the insert carrier is continuous over the side edge thereof and the corresponding semicylindrical support surface in the recess on the holder are both continuous from a base surface to simplify the machining thereof. In addition, the support surfaces effect a good transmitting of forces between the respective components to enhance the durability of the tool.
