Claim:
A cutting arrangement for cutting a workpiece comprising: a tool holder comprising a shank configured to be inserted into a machine and a body connected to said shank; said tool holder having a central longitudinal axis; said tool holder body having a substantially planar end face disposed transverse to the central longitudinal axis of said tool holder, and side faces extending from and transverse to said end face; said tool holder body comprising a plurality of tool receptacles, each being configured to receive a fastening shank of a cutting tool therein; a plurality of clamping devices, each being configured to retain a fastening shank of a cutting tool in a corresponding one of said tool receptacles; each of said tool receptacles comprising: a first bore hole being disposed to open in said end face and being configured to permit a fastening shank of a cutting tool to be inserted there through; and a second bore hole being disposed to open in one of said side faces and being configured to permit a corresponding one of said clamping devices to be inserted there through; and each of said clamping devices comprising: a clamping screw being configured and disposed to extend transverse to the central longitudinal axis of said tool holder in a corresponding one of said second bore holes; a threaded locking ring being screwed into a corresponding one of said second bore holes and being disposed immediately adjacent the second bore hole opening in a corresponding one of said side faces; said clamping screw comprising a screw head being configured to receive a portion of a turning tool therein to permit rotational adjustment of the position of said clamping screw; said screw head being disposed inside said locking ring, wherein the diameter of said screw head is substantially similar to the inner diameter of said locking ring to align said clamping screw in its corresponding second bore hole and to minimize movement of said clamping screw in a direction transverse to the rotational axis of said clamping screw; said clamping screw comprising a projecting shoulder portion disposed adjacent said screw head; and said locking ring comprising an annular end face being configured and disposed to engage said projecting shoulder portion to retain said clamping screw in its corresponding tool receptacle.
