COLLET AND LOCK NUT

摘要

An assembly generally comprises a collet (12) for receiving a cutting tool shank (34) and a lock nut (16) for creating a gripping force between the collet (12) and the cutting tool shank (34). The collet (12) has a nose (100) and the lock nut (16) has a front face (74) that is substantially flush with the nose (100). The lock nut (16) further has a fastening element that mates with a fastening element of a coolant sealing ring (18) for attaching the coolant sealing ring (18) to the lock nut (16) so that the coolant sealing ring (18) may be detached from the lock nut (16).
