摘要： A metal cutting tool comprising a cutting insert (1) having a cutting portion (7) and a tail portion (9) formed integrally therewith, a tool holder (2) having a holder head portion (18) formed with an insert retaining pocket (20) adapted to receive the insert tail portion (9) and a clamping screw (3). Upon the tail portion (9) being received in the pocket (20), a tail portion base (11) bears on a pocket base (22) and tail portion side walls (12) are disposed adjacent pocket side walls (23). Insertion of the clamping screw (3) into a through bore (15) of the tail portion aligned with a threaded pocket bore (26) and consequent screw coupling of a screw thread portion (6) in the threaded pocket bore (26) results in a clamping portion (4) of the screw bearing clampingly against a clamping engaging portion (17) of the tail portion through bore. As a consequence, the tail portion base (11) is biased against the pocket base (22) and a tail terminal portion (13) is biased towards an inner portion of the pocket (20) so as to ensure a contact between clamping surfaces of the side walls (12) of the tail portion and of the side walls (23) of the pocket (20).

摘要： A cutting insert having a cutting head (1) and a coupling shank (2) integral at one end thereof with the cutting head (1) and including a screw threaded portion (4). The cutting insert is formed by a powder metallurgy process of compacting and sintering and the screw threaded portion (4) is constituted by a substantially cylindrical body having a pair of diametrically opposed, longitudinally truncated planar portions (5) interposed between substantially curved cylindrical portions (6) having arcuate surfaces on which there are formed a non-continuous screw thread (7), the arcuate surfaces extending between 50 to 85% of the total peripheral extent of the cylindrical body of which they form part. There is also disclosed a powder metallurgy process for manufacturing the cutting insert.
