In a cutting tool a retention pin (12) releasably holds an insert (10), or an insert and seat, in place in a recess (20) of a cutter body (13). The retention pin (12) is fabricated from a blank having a cylindrical body portion (34) with a first axis (40) concurrent with the axis of the cylindrical head thereof (32), the body portion thereafter being threaded on a second axis (46) angularly disposed with respect to the first axis (40) and intersecting the same at about midpoint (42) of the body portion (34). When the thus threaded pin is inserted into the bore, it rotates the head portion (32) about the second axis (46), thereby to force the cutter insert (10) against the supporting shoulders (22) while drawing the insert into engagement with the seat. |
