ABSTRACT:
A cutting tool (10) comprises a shank (12) for receiving a cutting insert (14) and a block (16) for delivering a flow of fluid to the cutting insert (14). Fluid is delivered to the cutting insert (14) through a fluid passageway (18) that extends through the shank (12) and the block (16). The block (16) is pivotable mounted on the shank (12). The block (16) pivots about screw (22) between a first and a second position. In the first position the block (16) is held in sealing arrangement with the shank (12) to allow the passage of a coolant through the fluid passage (18) to the cutting insert (14). In the second position the block (16) has moved to allow removal of the cutting insert (14) from the shank (12).
