Patent ID: 7905688

Claim:
A milling tool, comprising: a tool shank defining an axis of rotation D; a cutter region formed as a cutting head consisting of wear-resistant material and having at least one planar cutting edge running approximately perpendicularly with respect to the axis of rotation D; said planar cutting edge merging peripherally into a main cutting edge and merging centrally into a secondary cutting edge, and each of the planar, main, and secondary cutting edges being contemporaneously effective for cutting during an operation of the milling tool; said secondary cutting edge being offset rearwardly with respect to said planar cutting edge in a direction of the axis of rotation D; a transitional zone between said planar cutting edge and said secondary cutting edge having at least one notch formed therein, produced as a cutting edge portion and having a rearmost point, as seen in an end view in the direction of the axis of rotation D, lying behind a forward-most point of said secondary cutting edge; said planar cutting edge and an adjoining portion of said notch enclosing an angle α in a range of 90°-175°; said planar cutting edge and a portion of said notch adjoining said secondary cutting edge enclosing an angle β in a range of 3°-90°; said secondary cutting edge and a portion of said notch adjoining said secondary cutting edge enclosing an angle γ in a range of 90°-177°.
