Patent ID: 8388272

Claim:
A milling cutter, comprising: a shank and an upper portion having an insert pocket, the insert pocket including a bottom surface with a threaded bore, a radial support wall and an axial support wall, the upper portion further including a pin hole; a cutting insert capable of being mounted in the insert pocket by a threaded fastener passing through a countersunk bore of the cutting insert, the cutting insert having a top surface, a bottom surface, and a plurality of side surfaces extending from the bottom surface to the top surface, the cutting insert further including a hole having a center axis that extends from the bottom surface of the cutting insert; and a tapered pin having a tapered upper portion with a center axis and a lower portion, at least a portion of the upper portion capable of being received in the hole of the cutting insert when the cutting insert is mounted in the insert pocket, at least a portion of the lower portion capable of being received in the pin hole when the cutting insert is mounted in the insert pocket, the center axis of the tapered pin being offset by a distance with respect to the center axis of the hole when the cutting insert is mounted in the insert pocket, wherein the cutting insert is mounted in the insert pocket by inserting the threaded fastener through the countersunk bore and threading the threaded fastener into the threaded bore, and wherein rotation of the threaded fastener when mounting the cutting insert in the insert pocket causes the upper portion of the tapered pin to exert pressure against the hole of the cutting insert, thereby causing one of the side walls of the cutting insert to be forced against the radial support wall of the insert pocket.
