A replaceable cutting head includes a forward cutting portion and a rearward mounting portion. The mounting portion includes a male coupling member that protrudes rearwardly from a base surface. The male coupling member includes three circumferentially spaced apart head fixation members, where each head fixation member has a head peripheral surface that spirals inwardly in a direction against the direction of rotation and diverges. A tool holder includes a female coupling member extends rearwardly from a holder forward surface. The female coupling member includes three circumferentially spaced apart holder fixation members, where each holder fixation member has a holder peripheral surface that diverges rearwardly. When a cutting tool, which includes said cutting head and tool holder, is in a locked position, the male coupling member of the replaceable cutting head is removably retained within the female coupling member of the tool holder by means of a self-lock mechanism. |

1. A replaceable cutting head (22), for rotary cutting operations, having a head longitudinal axis (A) around which the replaceable cutting head (22) rotates in a direction of rotation (R), the head longitudinal axis (A) extending in a forward (DF) to rearward direction (DR), comprising:
a forward portion forming a cutting portion (26) and a rearward portion forming a mounting portion (28); the cutting portion (26) comprising:
a plurality of cutting members (30) extending radially with respect to the head longitudinal axis (A); and the mounting portion (28) comprising a male coupling member (40) protruding rearwardly from a base surface (42), the base surface (42) extending transversely with respect to the head longitudinal axis (A), and defining a boundary between the cutting portion (26) and the mounting portion (28), the male coupling member (40) comprising:
three circumferentially spaced apart head fixation members (44), each head fixation member (44) comprising a head peripheral surface (46) spiraling inwardly in a direction against the direction of rotation (R) and diverging rearwardly with respect to the head longitudinal axis (A).
