A cutting tool includes a cutting head including a rearward mounting portion and a head through hole. The mounting portion includes a male coupling member having a non-cylindrical, conically shaped head abutment surface, and at least two driven projections. The cutting tool includes a tool holder having a holder pocket which includes a female coupling member having a non-cylindrical, conically shaped forward holder abutment surface, at least two driving recesses and an internal threaded hole. In a locked position, the male coupling member is removably retained in the female coupling member by a fastening screw located in the head through hole and threadingly engaged with the holder internal threaded hole. The head abutment surface abuts the forward holder abutment surface thereby forming a secure coupling between the male and female coupling members. The driven projections are located in the driving recesses for providing torque transfer between the two parts.
A replaceable cutting head (22), for rotary cutting operations, having a head central axis (A), defining opposite forward and rearward directions (DF, DR), and opposite rotationally forward and rearward directions (RF, RR) with the rotationally forward direction (RF) being the cutting direction, the replaceable cutting head (22) comprising:
A tool holder (24), having a holder longitudinal axis (C) defining opposite forward and rearward directions (DF, DR), and opposite rotationally forward and rearward directions (RF, RR) with the rotationally forward direction (RF) being the cutting direction, the tool holder (24) comprising a holder pocket (79) extending rearwardly from a holder forward surface (70), the holder forward surface (70) extending transversely with respect to the holder longitudinal axis (C);
