Description: |
| Abstract:
A cutting tool of the type having a recess or pocket at one axial end thereof in which a disposable cemented carbide cutting insert is held by an overhead clamp which also acts to pull the insert back into the pocket. A separate chip breaker plate is releasably attached to the clamp. The means for attachment of the chip breaker plate to the clamp extends through the chip breaker to the clamp and contains a projection below the chip breaker plate which fits within the hole in the insert, so that tightening of the clamp pulls the insert simultaneously toward the shoulder and the base of the recess to firmly clamp the insert in the recess of the shank. |
