Patent ID: 8556551

Claim:
A cutting tool ( 10 ) comprising: a shank ( 16 ) having a circumferential groove ( 26 ); an adjustment ring ( 22 ) releasably secured to the shank ( 16 ) at the groove ( 26 ), the adjustment ring ( 22 ) comprising: a threaded through bore ( 40 ) in which a screw ( 24 ) is screw mounted, the screw ( 24 ) projecting inwardly of the adjustment ring ( 22 ) for engaging the groove ( 26 ); an adjustment member ( 44 ) for engaging the groove ( 26 ), the adjustment member ( 44 ) being positioned diametrically opposite the threaded through bore ( 40 ) and projecting inwardly of the adjustment ring ( 22 ); wherein the screw ( 24 ) is rotatable in the threaded through bore ( 40 ) to exert a purely radially directed force on the groove ( 26 ), thereby inducing displacement of the adjustment member ( 44 ) radially inwardly, whereby the adjustment member ( 44 ) exerts non-radially directed forces on the groove ( 26 ), thereby inducing a bending moment on the shank ( 16 ).
