Milling cutter

A milling cutter, comprising:

• a cartridge to which a tip having a cutting edge is affixed,
• a body in which a pocket for insertion of the cartridge is formed,
• an affixation tool having an inclined surface and a vertical surface opposite of the inclined surface, and
• a shank connected to the body, wherein:
• the body has an affixation tool insertion hole formed radially inward from the pocket toward an axis of rotation of the milling cutter such that the affixation tool insertion hole is between the pocket and the rotation axis, and a partition wall is between the pocket and the affixation tool insertion hole,
• the affixation tool is inserted into the affixation tool insertion hole of the body with the vertical surface facing the partition wall, and the vertical surface of the affixation tool exerts a radially-outward force on the partition wall of the body in a radial direction opposite to the radially inward direction, thereby elastically deforming the partition wall,
• the pocket is formed so as to produce a counterforce countering a radially-outward force acting on the cartridge inserted in the pocket via the partition wall,
• the cartridge is affixed in the pocket based on the radially-outward force acting due to elastic deformation of the partition wall, and
• in a cross-section perpendicular to the rotation axis, one of the pocket and the cartridge has a non-circular cross-sectional shape and the other of the pocket and the cartridge has a circular cross-sectional shape such that the pocket provides contact portions engaging the cartridge alternating with non-contact portions spaced apart from the cartridge.
