Abstract: A cutting tool includes a chuck, a compressible conical collet and a lock nut for locking the collet. The cutting tool lock nut has a nut portion with a threaded portion for threading with the chuck, and a locking portion with a collet-locking surface formed with angled coolant grooves thereon. The collet-locking surface presses on the collet head, thereby compressing it to grip a tool shank in a collet bore thereof. As the locking portion presses only against a peripheral surface of the collet head, the lock nut is suitable for locking collets with different bore diameters. When the chuck is provided with a coolant fluid, the coolant fluid flows through the chuck and through the collet towards the locking portion, passing through the coolant notches between the locking portion and the collet head, and sprayed towards a location along the tool shank.
