    摘要： A cutting tool having a tool holder assembly for removably securing a plurality of cutting inserts. The tool holder assembly includes a tool holder body with an insert receiving pocket formed in a front end portion thereof, and a multi-insert tool clamp connected to the tool holder body. The clamp has a tool holder connecting portion and an insert clamping portion spaced apart therefrom, the insert clamping portion including a clamping protrusion and a plurality of clamping fingers. A clamping passage separates the plurality of clamping fingers from the clamping protrusion. At least one clamping slot separates the plurality of clamping fingers, and a slot plane longitudinally bisects each clamping slot. The clamping protrusion laterally extends along a clamping axis transverse to the at least one slot plane, and the at least one slot plane intersects the clamping protrusion.

    摘要： A cutting insert has a cutting portion corner formed at the intersection of a rake surface, a forward cutting portion surface and a relief surface. A cutting edge is formed at an intersection of the rake surface and the relief surface with a land that is located on the rake surface and that extends along, and negatively away from, the cutting edge. A chip-control arrangement is located at the rake surface and includes an elongated projection and plurality of spaced apart elongated protuberances that extend from the projection to the cutting edge, so that the land has a plurality of spaced apart bulging land portions. A non-rotary cutting tool has an insert holder having an insert pocket and the cutting insert releasably retained therein.
