ABSTRACT:
A cutting tool in which a retention pin releasably holds an insert, or an insert and seat, in place in a recess of a cutter body. The retention pin is fabricated from a blank having a cylindrical body portion with a first axis concurrent with the axis of the cylindrical head thereof, the body portion thereafter being threaded on a second axis angularly disposed with respect to the first axis and intercepting the same at about the mid-point thereof. When the thus threaded pin is inserted into the bore, it rotates the head portion about the second axis, thereby to force the cutter insert against a supporting shoulder while drawing the insert into engagement with the seat. A retaining lip is provided on the shoulder to prevent tipping of the insert when such is forced into operating position.
