Tungaloy DNMG150608-SF AH630 Carbide Turning Insert (10pc)

This is a factory-new, sealed box of 10 Tungaloy DNMG150608-SF AH630 carbide turning inserts (also designated DNMG 442 SF AH630 in inch notation), made in Japan. Decoding the ISO designation: D = 55° diamond shape, N = 0° clearance angle, M = tolerance class M, G = cylindrical hole with chip grooves on both faces, 15 = 15.875 mm inscribed circle, 06 = 6.35 mm thickness, 08 = 0.8 mm nose radius; the SF chipbreaker geometry is a positive-rake, low-cutting-force design optimized for stainless steel (ISO M materials). The AH630 grade is a PVD-coated (TiAlN-based multilayer) submicron carbide substrate engineered by Tungaloy for superior toughness and wear resistance in stainless steel and difficult-to-cut materials, with a characteristic dark black/violet PVD appearance visible in the photos. Recommended cutting data per label: feed 0.1–0.4 mm/rev (0.004–0.016 ipr), cutting speed 90–190 m/min (300–620 sfm); applicable ISO material groups are P, M, K, N, S, and H per the label's color-coded chart, with M (stainless) as the primary target. These inserts are compatible with standard DDJNR/DDJNL and equivalent toolholders accepting DNMG 55° diamond inserts.
