Tooling insert with mating surface

A tool holding system, comprising:

• a tool holder including a seat and a clamping device having a clamping end aligned with a surface of the seat;
• a shim mounted in the seat of the tool holder, the shim including a receiving surface oriented to open toward the clamping end of the clamping device;
• and
• a monolithic cutting insert mounted in contact with the receiving surface, the cutting insert including one or more cutting edges at an intersection of a first face and a clearance surface, the first face in contact with the clamping end of the clamping device, and a plurality of radially oriented features on a mating face in contact with the receiving surface, wherein the receiving surface has corresponding features to that of the mating face of the cutting insert and wherein a radius containing one of the plurality of radially oriented features forms an acute angle, an obtuse angle or a right angle to a radius containing a second of the plurality of radially oriented features,
• wherein the plurality of radially oriented features includes at least two adjacent ridges including V-shaped peaks separated by a groove including a V-shaped base, and
• wherein the plurality of radially oriented features includes alternating ridges and grooves, wherein a ridgeline of each ridge is oriented to intersect at a common point.
