Abstract:
A cutting tool which includes a mounting shaft and a chip breaker positioned on the mounting shaft. A cutting plate is supported between the mounting shaft and the chip breaker, with a clamping jaw being positioned on the chip breaker. A clamping screw is releasably held in the cutting tool mounting shaft for holding the clamping jaw and the chip breaker against the tool mounting shaft. The clamping screw has a longitudinal axis and an outer portion which is situated externally of the clamping jaw. A spring is provided for urging the chip breaker against the clamping jaw. The clamping jaw and the chip breaker have inter-engaging teeth on their surfaces which are oriented towards one another. The chip breaker further includes a through-going aperture through which the clamping screw passes. The through-going aperture is enlarged to form an elongated opening for permitting lateral movement of the chip breaker transversely to the longitudinal axis of the clamping screw. |
