FIELD: machine building.
SUBSTANCE: invention relates to machine building and can be used for machining small parts from hard-to-machine materials using end mills. Cutter comprises cutting part in form of truncated cone, changing into cylindrical shank end, and comprises two cutting teeth, each of which is located along screw spiral, with lifting angle 30° and has front and rear surfaces made at inclination angle of 30° and 60° respectively to form a rhomb shape cutting part. End face of cutting part is made with a spacing, crossing said front and rear surfaces with formation of cutting edge.
