FIELD: manufacturing technology.
SUBSTANCE: cutting plate (12) for tool (10) is intended for machining part and comprises first cutting edge (22) and first hole (32), has elongated shape and extends substantially in lengthwise direction (18). Cutting plate first hole (32) extends along axis (36) extending perpendicular to lengthwise direction (18) of cutting plate. Cutting plate (12) comprises crosswise protrusion (30), which is located on side (28) which is oriented perpendicular to axis (36) of first hole. At that, on ledge (30) there are first side surface (40a) of contact with holder, axial surface (42) of contact with holder and first horizontal surface (44a) of contact with holder for working contact of cutting plate (12) with tool holder (14), wherein first side surface (40a) extends substantially perpendicular to axis (36) of first opening, and wherein axial surface (42) of contact with holder and first horizontal surface (44a) extend perpendicular to first side surface (40a) of contact with holder and across each other friend.
EFFECT: higher resistance and accuracy of cutting tool.
