摘要: A reversible and indexable tangential milling insert includes two major surfaces a peripheral surface which extends therebetween. The mid-plane (M) located midway between the surfaces, an clamping bore with central axis (H). three side each of exactly cutting portions, relief portions minor abutment on opposite sides (M), continuously respective portion portion. Each edge, corner edge. In cross section along first imaginary plane perpendicular to (H), is concavely curved, surface, converge outwardly.
