Abstract:
1. A machining tool, comprising: a cutting plate having a cutting edge projecting radially from a central body thereof; a shaft-like holder having a longitudinal axis and a seat on a frontal surface of said holder receiving said cutting plate, said seat having grooves with side walls forming driving surfaces and support surfaces; a bore in said central body coaxial with said longitudinal axis to receive a fastening screw for securing said cutting plate axially on said seat of said holder; a coupling component on said central body for mounting said central body on said seat, said coupling component having three ribs projecting from an end surface of said central body and extending radially, said ribs having flanks with coordinated surfaces and being complementarily shaped to said grooves for transfer of operating torque and securing axial positioning; and limited component surfaces formed on said driving surfaces and said support surfaces of said side walls of said grooves, remaining portions of said driving surfaces and said support surfaces being retracted from said component surfaces providing a space between said ribs and said remaining portions of said driving surfaces and said support surfaces, said component surfaces being projecting wall components aligned opposite one another on both of said side walls of said grooves.
