    摘要： A toolholder (25; 25') includes a bottom abutment surface (27; 27'), a projection (29; 29') extending upwardly from the bottom abutment surface (27; 27'), the projection (29; 29') including an internally threaded opening (31; 31'), the internally threaded opening (31; 31') having a central axis that is offset from a central axis of the projection (29; 29') in a first direction, and a clamping screw (33; 33') having external threads (35) for mating with internal threads of the internally threaded opening (31; 31') and a head (37; 37') having a bottom clamping surface (39; 39') shaped as a truncated cone for contacting an insert clamping surface (41; 41') and urging an insert (23; 23') substantially in a first direction (D1; D1') when the clamping screw (33; 33') is tightened relative to the toolholder (25; 25') and the insert (23; 23'). The toolholder (25; 25') also includes at least one abutment member (43; 43'), particularly a replaceable circularly cylindrical pin, extending from a side wall (45; 45') of the projection (29; 29') in a radial direction, each abutment member having an abutment point, at least the abutment point of the at least one abutment member (43; 43') being closer to the central axis (C3; C3') of the projection (29; 29') than to the central axis (C1; C1') of the internally threaded opening (31; 31').

    摘要： A polygonal cutting insert for right angle machining has opposed upper and lower surfaces, a peripheral side surface interconnecting the upper and lower surfaces and having curved first and fourth side surfaces and plane second and third side surfaces, and main and secondary cutting edges alternately formed along the outer peripheries of the upper and lower surfaces. The adjacent main and secondary cutting edges form a right angle therebetween. The first side surface adjoins the main cutting edge of the upper surface. The second side surface adjoins the secondary cutting edge of the lower surface. The third side surface adjoins the secondary cutting edge of the upper surface. The fourth side surface adjoins the main cutting edge of the lower surface. The cutting insert is mounted on a milling cutter at a positive axial rake angle.
