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).
Claims10
A cutting tool comprising:
- a cutting insert;
- a shank for receiving said cutting insert;
- and
- a block mounted on the shank adjacent to the cutting insert, the block having at least one fluid passage for delivering a flow of fluid to the cutting insert, the block extending over at least a portion of the cutting insert, the fluid passage extending through both said shank and said block, wherein the block is pivotably mounted on the shank so that the block can move between a first position in which said fluid passage in the shank and the block are in fluid communication so that in operation a flow of fluid passes through the fluid passage to the cutting insert and a second position in which the fluid passage in the shank and the block are not in fluid communication and to allow removal of the cutting insert.
(canceled)
A cutting tool comprising:
- a cutting insert;
- a shank for receiving said cutting insert;
- and
- a block mounted on the shank adjacent to the cutting insert, the block having at least one fluid passage for delivering a flow of fluid to the cutting insert, the block extending over at least a portion of the cutting insert, the block is pivotably mounted on the shank so that the block can move between a first position whereby in operation a flow of fluid passes through the fluid passage to the cutting insert and a second position to allow removal of the cutting insert, wherein a locking mechanism is provided to hold said block in sealing relationship with said shank, and wherein said locking mechanism comprises a pivotal member mounted on the shank that engages with a recess in the block.
