Abstract: A cutting tool has a recess for receiving a cutting insert having a clamping depression on the rake face. The cutting insert is held in the carrier tool by a clamping finger having a lug. The clamping finger being secured on the carrier tool via a clamping bolt so that when tightening the clamping bolt, the clamping finger pulls the cutting insert into the recess. A sickle-shaped engagement element engages into the clamping depression of the cutting insert being arranged on the lug. The clamping bolt has a clamping head overhanging its shank. The clamping head is seated on an angled locating surface of the clamping finger with respect to the axis of the clamping bolt, wherein said surface is arranged so compression force of the clamping finger on the cutting insert is enhanced. The lug has a clamping surface for bearing on the rake face of the cutting insert.

Abstract: A cutting insert includes a body that forms top and bottom surfaces, and a center hole intersecting at least the top surface (e.g., a through-hole). A portion of the top surface which extends around the center hole includes an array of projections radiating laterally outwardly around the center hole. A distal end of each projection disposed farthest from the center hole defines a tip of the projection. The projections form at least six tips spaced circumferentially apart. Each tip has a planar top face. A clamp has flat contact surfaces which press downwardly against the planar top faces of respective projections simultaneously as the clamp pulls the insert against an upstanding support surface.

Abstract: A cutting insert is clamped in a pocket of a holder by a top clamp assembly which includes a clamp arm screwed to the holder, and a clamp plate interposed between the insert and a front part of the clamp arm. The clamp plate is formed of a harder and more wear-resistant material than the clamp arm and transmits clamping forces from the clamp arm to the cutting insert. The hard clamp plate shields the clamp arm from being impacted by chips generated during a machining operation, thereby minimizing wearing of the clamp arm.

Abstract: The clamping mechanism and companion cutting insert disclosed are designed for use in a milling cutter intended to be ganged with other like cutters on a common rotational axis for the simultaneous milling of multiple slots or grooves. The axially movable clamp for the on-edge inserts employed in the cutter is operated indirectly by an adjusting screw accessible radially from the outside of the ganged cutter bodies without requiring disassembly of the individual cutters to index or replace the cutting inserts. In each of several clamping mechanisms disclosed, the ultimate clamping element or detent takes the form of an arm which is rocked into engagement with the insert at the site of a blind depression in the face of the insert, being drawn in the axial direction by inward adjustment of a radially accessible adjusting screw, and rockable in the reverse direction by a return spring to release the insert as the adjusting screw is backed off.The relatively thin inserts for the described service do not have the usual through hole typically found in on-edge inserts, but are provided instead with blind depressions in their major surfaces while the clamping arm is formed cooperatively with the insert depression to provide axial clamping force with a radially inwardly directed component.
