摘要： A locking structure for locking a cutting insert to a tool holder, the insert having a generally hour-glass shaped lockscrew receiving aperture therethrough. The lock-screw is provided with a head having a lower section which flares outwardly from the shank, a central cylindrical section and an upper section which converges in generally frusto-conical fashion. The axis of the lock-screw receiving aperture in the tool holder is slanted toward the plane or planes of one or more locating abutments on the holder. The components, when assembled, provide a positive lockdown for the insert in the tool holder, force the insert positively against the locating abutment or abutments and, yet, permit the insert to be removed without complete removal of the lock-screw.
