Hole-making tool

A hole-making tool comprising:

• a basic body having a seat, the seat being delimited by a tangential support surface, an axial support surface, and a radial support surface that is situated closest to a center axis of the tool;
• and
• a replaceable cutting insert removably disposed on the basic body, the cutting insert having an upper side, an underside and a plurality of side contact surfaces, the cutting insert being fixed in the seat by a tightening member that holds the underside of the cutting insert pressed against the tangential support surface of the seat, and two of the side contact surfaces against the axial and radial support surfaces of the seat, wherein an interface between the tangential support surface of the seat and the underside of the cutting insert includes at least one pair of male- and female-like securing means, the female-like-securing means including an elongate guide surface that extends at an acute angle in relation to the radial support surface of the basic body from the direction of the axial support surface, the male-like securing means being spaced apart from the guide surface and wherein a gap is formed between the pair of securing means as long as the cutting insert is kept pressed against the axial and radial support surfaces by cutting forces.
