CUTTER TIP Russian patent published in 2012 - IPC B23C5/20 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and be used in cutters. Square indexing tip has four side surfaces to connect tip end surfaces. Main cutting edge is located on intersection of each side surface with end surface to pass from tip angle along first side surface downward toward central surface. Fanning edge extends from the same angle of tip along appropriate side surface upward from central surface and is located above appropriate thrust surface of end surface. Geometry of tip and its seat is selected to impart main cutting edge a negative axial inclination. Note here that tip features, in fact, negative axial angle of location to allow axial rear angle and, generally, negative radial location angle and, generally, negative radial location angle to provide for radial rear angle.

EFFECT: improved machining conditions, higher efficiency.
