Abstract

A cutting insert (1) of a hard material comprising a generally conical tip portion (6) which includes a tip and a base; a first tapered conical portion (7) having first and second ends, with the first end adjacent the base of the tip portion (6) and the second end having a greater diameter than that of the first end; a transition portion (8) having first and second ends and defining a radius of curvature therebetween, with the first end adjacent the second end of the first tapered conical portion (7), a second tapered conical portion (9) having first and second ends with the first end adjacent the second end of the transition portion (8) and the second end having a greater diameter than the first end; a shoulder portion (10) having first and second ends with the first end adjacent the second end of the second tapered conical portion (9) and having a greater diameter thereto. Also, an extracting tool comprising an elongated tool body (2, 4) having an end which is configured and dimensioned to provide a support surface for a cutting insert (1) as described above.
