Side milling cutter

A side milling cutter, comprising:

• a main body extending along a predefined rotational axis from a first end having an interface for connection to a rotational drive to a free second end having a bearing face;
• a disc-shaped cutter holder fastened to said second end and having a first main surface facing said main body and being supported on said bearing face, said disc-shaped cutter holder having a second main surface lying opposite said first main surface, said disc-shaped cutter holder having an outer circumference projecting radially from said main body, and said disc-shaped cutter holder having a central through opening penetrating said disc-shaped cutter holder axially;
• a plurality of coolant feed channels configured in said main body for feeding coolant to said second end of said main body;
• a plurality of coolant distributing channels configured in said disc-shaped cutter holder for feeding coolant to said outer circumference of said disc-shaped cutter holder, said coolant distributing channels having a closed configuration toward said first main surface and toward said second main surface, and said coolant distributing channels each having:
• a first channel portion running in an interior of said disc-shaped cutter holder,
• at least one outlet opening on said outer circumference of said disc- shaped cutter holder, and
• an inlet portion being open towards said through opening and towards said first main surface and extending only over a part of a thickness of said disc-shaped cutter holder in a region of said through opening;
• and
• a common coolant distributing chamber configured between said main body and said disc-shaped cutter holder, at least two of said plurality of coolant distributing channels branching off from said common coolant distributing chamber, and at least two of said plurality of coolant feed channels opening into said common coolant distributing chamber.
