Sumitomo SEET13T3AGSN-G ACZ350 Square Carbide Milling Insert (10 pcs)

The Sumitomo Electric SEET13T3AGSN-G is a new, square-shaped (S) double-sided positive-geometry carbide milling insert in the ACZ350 grade, packaged in a standard 10-piece tray. Decoded per ISO 1832: S = square shape, E = 20° clearance angle, E = close tolerance (±0.025 mm on thickness/inscribed circle), T = clamping hole with chipbreaker on both faces, 13T3 = 13 mm inscribed circle / 4.76 mm thickness, A = 0.4 mm nose radius (or chipbreaker variant), GSN = Sumitomo proprietary chipbreaker designation for general-purpose negative/positive milling, G suffix = ground peripheral edge. ACZ350 is a PVD-coated (TiAlN-based bronze/copper-colored finish) cemented carbide grade rated for P, M, K, H, N, and S workpiece material groups as confirmed by the package label, making it suitable for milling steel, stainless, cast iron, hardened materials, non-ferrous alloys, and heat-resistant superalloys. The insert's double-sided geometry delivers up to eight usable cutting edges, and the ground peripheral edge provides enhanced dimensional accuracy; compatible toolholders accepting SEET13T3 square milling inserts from Sumitomo's SE-style face mill and shoulder mill bodies (e.g., ASX445 and similar platforms).
