Claim:
A cutting tool ( 12 ), comprising: a tool body ( 11 ) having at least one insert pocket ( 16 ) provided with a generally planar base surface ( 17 ); a cutting insert ( 18 ) releasably retained in the insert pocket ( 16 ) and supported by the generally planar base surface ( 17 ), the cutting insert ( 16 ) comprising a peripheral side surface ( 14 ), the peripheral side surface ( 14 ) comprising a minor side surface ( 22 ); an adjustment screw ( 26 ) positioned in a cavity ( 28 ) formed adjacent the insert pocket ( 16 ), the adjustment screw ( 26 ) capable of rotating about an adjustment screw rotation axis (R) thereof; an adjustment wedge ( 24 ), accommodated in the cavity ( 28 ), the adjustment wedge ( 24 ) comprising a female threaded section ( 48 ) configured to threadingly engage a male threaded section ( 30 ) of the adjustment screw ( 26 ); wherein rotation of the adjustment screw ( 26 ) in a given direction results in an inclined sliding motion of the adjustment wedge ( 24 ) relative to the minor side surface ( 22 ) of the cutting insert ( 18 ); wherein by virtue of the sliding motion, the adjustment wedge ( 24 ) is capable of displacing the cutting insert ( 18 ) along an adjustment axis (A) parallel to the base surface ( 17 ); wherein the adjustment screw ( 26 ) is constrained to maintain its position in the cavity ( 28 ); and wherein the adjustment screw ( 26 ) includes a screw head ( 32 ) supported by a lower surface ( 27 ) of the cavity ( 28 ) and partially accommodated in a lower groove ( 44 ) in a front wall ( 40 ) of the cavity ( 28 ) adjacent the lower surface ( 27 ).
